Let me set the scene for you. It’s Christmas Eve. Midday. I’m getting ready to head to the elliptical before finishing wrapping presents. Mom’s wrapping presents much better than I do (on the ironing board, which is a pretty genius way to do it). Dad’s about to vacuum. Then it happens.
The power goes out. On Christmas Eve. Pretty much my worst nightmare. Okay, so the power going out is always among my worst nightmares.
After a moment . . . or more of panic, I reported the outage. The restoration estimate was two hours away. I did take a bit of a sigh of relief, but estimates are just that . . . estimates.
Dad coolly read a book and divided up some of my old toys to give to friends. Mom went on with wrapping presents. And I panicked and exercised while I wore out my laptop battery playing iTunes. For the record, “Shake it Off” didn’t really help me shake my anxiety, but it did make my workout go fast.
Nearly exactly two hours later, the power came back on. With winds expected that night, my anxiety didn’t vanish, but I was definitely happy. The power company saved Christmas. The house didn’t get too cold. The food in the refrigerator and freezer was fine. The lights could go on.
I later Googled the incident. The power company said in a newspaper article they didn’t know the cause. So that’s . . . comforting.
Regardless, the high winds died down, so there were no further incidents and we had a lovely Christmas. Plus, I’ll never forget the Christmas Eve the power went out and we had a thunderstorm. Yep, a thunderstorm.
Mostly, I was worried about the freezer because my last few pieces of this Sweet Potato Sheet Cake are stashed there. I would have been sad to see any of this amazing treat go to waste. The original recipe calls for pumpkin, but sweet potato is pumpkin’s more flavorful cousin. It provided great flavor and moisture to these cake, and complemented the warming spices perfectly.
Then there’s the silky smooth, just sweet enough cream cheese frosting. I could eat it with a spoon, but it’s definitely better with the cake. Pecans decorated the top, adding another dimension of flavor and texture. You could also put a cup of pecans in the cake if you wish.
Just make this cake. You’ll be as thankful as I was when the power came back on.
PrintSweet Potato Sheet Cake
- Total Time: 55 minutes
- Yield: 12 generous servings 1x
Ingredients
Cake
- 1 cup vegetable oil
- 2 cups granulated sugar
- 4 large eggs
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- ½ teaspoon kosher salt
- 2 teaspoons ground cinnamon
- 1 teaspoon ground ginger
- ½ teaspoon ground cloves
- 2 cups mashed sweet potatoes
Frosting
- 1 stick unsalted butter, room temperature
- 8 ounces cream cheese, room temperature
- 1 cup packed light brown sugar
- 1 ½ cups confectioners’ sugar

Instructions
- Make the cake. Preheat oven to 350 degrees F. Oil a 9 by 13 inch pan and set aside.

Those pictures are so beautiful! I love sheet cakes, and sweet potato cake (or pie) is such a fave.
If it’s any consolation, the day before Christmas Eve this year the pipes under my kitchen sink burst. Not fun…
Laura says
OMG, Julie, that would be horrible! I hope it was fixed quickly and you had a nice Christmas 🙂
