Momofuku Confetti Cookies

Confetti Cookie

Baking isn’t an exact science.  For some reason, people love to say that, but it just isn’t true.  Adding or taking away spices, sugar, fillings such as fruits or nuts, and even sometimes minor changes in flour or butter won’t give you a disaster as an end product.  Don’t get me wrong, 2 cups of flour instead of 1 is not going to end well, but 2 teaspoons of ground cinnamon instead of 1 most likely will.  Beyond that, if baking were an exact science, all recipes, if followed exactly, would turn out perfectly.  And I know from experience, and I’m betting a lot of you do to, that is not true.

There are variables in baking such as quality of ingredients and oven temperatures that the recipe author cannot predict or control, so it is up to us as bakers to not rely on that old adage, but instead use our instincts and unfortunately a little bit of trial and error.

I was reminded once again while making Confetti Cookies from the Momofuku Milk Bar Cookbook about that whole baking not being a science thing.  I followed the recipe word for word.  The first step, which I like doing the day before making the actual cookies, though this is not necessary, is making the Birthday Cake Crumb.  It’s super easy to make; I didn’t even use a mixer.  I baked them for the full time and they came out really crunchy.  Still yummy, but really crunchy.

Then it came time to make the cookies.  Everything went well, they looked good, were a little crumbly and I had to mash them together, but all in all, I felt confident I would end up with a quality final product.  I checked the cookies after 10 minutes of baking and found they were starting to brown on the bottom, but looked pretty raw on top.  After a couple more, they looked done enough to remove from the oven to save.  After they cooled for a few minutes, picking up these cookies while warm cannot be done without the cookie breaking into a bunch of pieces, my fears proved to be true: they were brown on the bottom, not quite burnt, just really, really brown.  Too brown for me.  They still tasted good, but failed to live up to my cookie and Momofuku expectations.  I resolved to make them again.

I am going to blame this on my new oven and the way it bakes, which I’m not a huge fan of.  I think there’s probably nothing wrong with the recipe, as I kind of think Christina Tosi from Momofuku is a genius and I don’t think she’d steer me wrong.  So, a lot less time, a lower oven temperature (325 degrees F instead of 350 degrees F), and higher oven racks later, I baked the cookies I was dreaming about.

There are a few steps to make these cookies, but they’re pretty easy to make, and they are definitely worth it.  Seriously, don’t be afraid of the process, these are fantastic.  The second batch tasted like I imagine they taste at Momofuku, as I’ve had, and loved, both the peanut butter and corn cookies straight from the source, and they have that same perfect flavor and kind of raw sugar/cookie dough flavor that is unparalleled in elsewhere in the cookie universe.

The Birthday Cake Crumb should be very moist when it comes out of the oven.  Most of it will harden, some of it won’t, it’s all amazing.  You only need half of the recipe for the cookies, but make the whole thing.  It’s great for snacking and I definitely think ¾ of it can make it into the cookie dough without a problem.  Eating one is perfection with the sweet flavor and the slightly crunchy, slightly crumbly, slightly soft texture.

Then there are the cookies.  They are barely crunchy, and instead chewy around the edges, while super soft with that scrumptious cookie dough thing in the center.  The bites with crumb have a little more crunch to them. Every bite is awesome, really, really awesome.  The flavor is very reminiscent of the boxed Funfetti cakes they’re inspired by, only way better.

This is one recipe where I would highly recommend using Davidson Pasteurized Eggs because the cookie batter is the best I’ve ever had.  If you make one less cookie so you can just eat the batter, I won’t tell.  It also killed me a little to use imitation clear vanilla extract, but Christina told me through Twitter (yes, I Tweeted with her!) it was important.  I used it; it’s good, but leaves a little aftertaste.  When I make them again, I just might try my pure vanilla extract.

You won’t regret making these cookies, but when you do watch them like crazy while they are baking.  Even with the reduced time and temperature, they were about a minute away from being too brown on the bottom.  While you make these, which you should really do, you’ll have to excuse me while I head to the freezer for one.

Momofuku Confetti Cookies
Prep time: 
Cook time: 
Total time: 
Serves: 15
Birthday Cake Crumb
  • ½ cup granulated sugar
  • 1 ½ tablespoons packed light brown sugar
  • ¾ cup cake flour
  • ½ teaspoon baking powder
  • ½ teaspoon kosher salt
  • 2 tablespoons rainbow sprinkles (I used Betty Crocker)
  • ¼ cup grapeseed oil
  • 1 tablespoon clear vanilla extract
Confetti Cookies
  • 2 sticks unsalted butter, room temperature
  • 1 ½ cups granulated sugar
  • 2 tablespoons glucose, or 1 tablespoon light corn syrup (I used the corn syrup)
  • 2 large eggs (the place to use pasteurized for sure)
  • 2 teaspoons clear vanilla extract
  • 2 ½ cups all-purpose flour
  • ⅔ cup milk powder (I used Carnation Instant Milk)
  • 2 teaspoons cream of tartar
  • 1 teaspoon baking soda
  • 1 ¼ teaspoons kosher salt
  • ¼ cup rainbow sprinkles
  • ½ recipe Birthday Cake Crumb (or a little more)
  1. Make the crumb. Preheat oven to 300 degrees F. In a medium bowl, mix together sugars, flour, baking powder, salt, and rainbow sprinkles until fully combined. Add the oil and vanilla. Stir until the addition of the wet ingredients causes clumps to form. All of the dry ingredients should be coated with the wet and clumps of various sizes should be present.
  2. Pour the clusters onto a parchment lined baking sheet. Spread them out so they are in roughly one thick layer. Do not spread them out thinly, leaving spaces between them, or they will overbake.
  3. Bake for 10 minutes. Stir and break them up slightly. Bake for a couple more minutes until they are starting to harden around the edges but are still very soft moving toward the center. Allow to cool completely on the baking sheet. They should harden, though some will be firmer than others, and some will be larger than others. This is perfect.
  4. Once cooled, they may be immediately used or eaten (they’re pretty delicious warm too), or stored in an airtight container at room temperature for up to 1 week or in the refrigerator or freezer for up to 1 month. They will continue to harden slightly the longer they sit.
  5. Make the cookies. Place the butter, sugar, and glucose or corn syrup in the bowl of a stand mixer fitted with the paddle attachment. Mix on medium-high for 2 to 3 minutes. Scrape down the sides of the bowl before adding the eggs and vanilla. Continue mixing on medium-high speed for 7 to 8 minutes, scraping down the bowl as necessary. A stand mixer is key, as it is vital to mix for the proper amount of time and on a pretty high speed. Add additional time for that missed while scraping down the bowl.
  6. Stop the mixer. Pour in the flour mixture, then mix on low speed, just until the flour is incorporated, no longer than 1 minute. Remove the bowl from the mixer and stir very briefly just to make sure all the flour is incorporated, as some may linger on the bottom of the bowl. Quickly stir in the crumbs until just combined.
  7. Using a regular sized ice cream scoop, scoop 15 mounds of dough onto 1 parchment lined baking sheet, 5 rows of 3. If the cookies need to be formed slightly, do so, then gently flatten the tops of the cookies slightly with fingers. Wrap the sheet tightly with plastic wrap before placing in the refrigerator for at least 30 minutes to chill. Do not skip this step or the cookies will not bake properly.
  8. Preheat the oven to 325 degrees F while the cookies are chilling. After the cookies have chilled, place them on three parchment lined baking sheets. The sheet used to chill the cookies may be used, however, use a new piece of parchment. Place 5 cookies on each sheet, about 4 inches apart, as far apart as possible. I highly recommend baking only one sheet of cookies per oven at a time. Otherwise they may burn on the bottom. Stash extra trays of cookies in the refrigerator while waiting to bake them.
  9. Bake the cookies for 10 minutes. After this time, look at the cookies, rotate if necessary, and make a rough estimation of how much more time they need to bake, probably 3 to 5 minutes. Use extreme caution if baking more than 5 additional minutes. The cookies may be lightly golden on the edges, but will be very pale and very soft in the center, looking underbaked, but they are not. Allow to cool completely on sheets; they will firm up.
  10. May be stored at room temperature in an airtight container for up to 5 days or in the freezer, wrapped in parchment and foil and placed in a zipper bag for up to 3 months. Enjoy!

  1. These are 5 star all the way. The texture is crispy to the touch but once you bite into it, it has a soft center. These are awesome a great suprise with the first bite. I asked for more samples when they came in to no avail they were gone.

    Great job on these cookies…

  2. Those cookies were very good! Alot of people (Me) that make homemade cookies somehow have a burned bottom from the baking sheet. Those were perfect with no burned taste. Eric, I believe I ate the last one! 🙂

    Thank you,

    Hey! Wait a minute, I didn’t get any of these, where was I? Darn they sure look good, I love those little candies in a cookie. If you ever do a do-over, send me some please.

  4. jackie jay says:

    These look fantastic! I am so disappointed that I couldn’t try them :(. Maybe I should actually try to make them myself? Hmmm….

    Thank you for all of your delicious recipes!!

  5. Arturo Spaccarotelli says:

    These are more like it. A sugar cookie with a crunchy sugar mixed in. My ideal as been met. Thank you for the sample, Aria’s disappointment when we told her we had no more is the highest praise I can give. No other treat would do the trick for this two year old. We look forward to the next round of taste testing.

  6. Jessica says:

    These cookies were fantastic Laura, great job! The recipe is a bit intimidating for someone who does not bake often, but Aria and I so loved these that I am likely going to have to give it a shot. They had such a great texture and the taste was exceptional – thank you again for such a delicious treat!

    • Hi Jessica, I’m so glad you liked the cookies. You really should give them a try. They aren’t that hard to make at all. My only advice is to make sure to mix the butter and sugar for the stated time and watch them very carefully while baking. Other than that I know you’ll have great success. Please let me know if you make them and how they come out! You can always send me an email with any questions too.

  7. cookies were very tasty enjoyed it,the only thing i thought it was a little to sweet,but still very good.

  8. stan the man says:

    The cookies are very good, kind of sweet. I think they would really be good for kids! Thank you for the treat, really good with coffee in the morning. I just have to convince my wife to try making them… maybe when our grandson comes to visit. Looking forward to trying your next fabulous recipe!

  9. These are one of my favorites.

  10. Oh my gosh. These look so incredibly chunky and crumbly and incredible and GOOD!

    • Thanks, Erica! These are the best cookies I’ve ever had! And for a Momofuku recipe, it wasn’t that hard. I made them twice because the first batch wasn’t perfect and felt like a pro by round 2 🙂

      • Oh man. I’m revisiting these because I was thinking about making them tonight. But 2 STICK OF BUTTER FOR 15 COOKIES?! That is a little insane. Maybe someday. I just wanted to drop you another comment to say that I am so in awe that you tweeted with Christina haha 🙂 That is awesome!

        • Erika, you could totally make the cookies smaller. I like big cookies and the recipe called for about 15 of them, but they are HUGE. I bet you could get 30 smaller but still super yummy cookies. You’ll just have to watch the bake time very closely. I love tweeting with Christina. She’s so cool! If you follow her on Twitter, she typically answers Tweet questions every Friday for awhile.

  11. Of all the C Tosi recipes Ive made, her cookies never really pan out for me. I feel like the butter ratio to the other ingredients is so high that they just spread and get too thin. Ive been tempted to make these and your post has me wanting to try them…but of all the cookies on your blog, would love to hear your faves! Your giant ginger cookies look amazing to me!

    • These are by far my favorite cookies. I have made these a couple times along with another Tosi cookie that I’m sharing right before Halloween, and I’ve never had an issue with them spreading too much. I find I sometimes have to push them down in the middle of baking. Mine are hard as rocks when I take them out of the refrigerator. I keep my refrigerator on the chilly side, so if yours aren’t really hard, I’d chill them in the freezer. I also turned down the oven temperature quite a bit on this recipe and a little on the other. That probably makes a big difference in how fast the butter melts. I hope you’ll give this recipe a try, but I also love my Vanilla Reese’s Pieces Cookies and Oatmeal Raisin Coconut Cookies. I liked the Giant Ginger Cookies, but they weren’t my favorite. I have another ginger cookie recipe that I’m going to try soon.
