A moist and easy sweet potato cake, baked in a 13×9 inch pan, then covered in delicious cream cheese buttercream frosting.
This cake recipe is perfect for fall. If you love spice cake or pumpkin cake, you’re going to love this one.
The great thing about this cake is that it’s also great to bring to any fall gatherings…something that everyone will love.
This cake takes a little preparation. You’ll need to have cooked the sweet potatoes ahead of time, but you can do that quickly in the microwave.
Once you’ve got that done, everything else comes together really quickly.
Hey there! Before you scroll, there’s lot’s of important stuff in the post!…including the FAQ section, which may answer any questions you might have about this recipe. Enjoy!
Now, let’s talk a little bit about just some of the ingredients for this recipe. (The entire ingredient list is in the recipe card lower in this post.)
All-purpose flour: There’s no special flour needed for this one…just use all-purpose flour.
Cinnamon, Ginger & Nutmeg: These are the spices that will give your cake that fall taste.
Light brown sugar: I love using brown sugar, especially in fall cakes as they really give a depth of flavor to your cake. Make sure to pack the sugar into your measuring cup.
Cooked, mashed sweet potatoes: I used real sweet potatoes (not canned) for this recipe. It’s easy to just cook these ahead of time (you can do it in the microwave) and then let them cool.
Unsalted butter & cream cheese: You’ll use these for the cream cheese buttercream. I’ve found that the name-brand cream cheese is the best and you’ll want both to be close to room temperature, but don’t microwave them.
*The recipe card close to the end of this post will go into all the ingredients and amounts.
Let’s talk a little about the mixing method for this cake.
The mixing method for this cake is insanely easy. You’ll just mix the dry ingredients together in one bowl, the liquid in another bowl, then pour the liquid into the dry mixture and mix.
You can use an electric mixer, or you could even use a wooden spoon.
When mixing the cream cheese buttercream, make sure to use an electric mixer as you’ll want to get it super creamy.
*All of the steps will be in the recipe card below.
Tips & FAQs:
Yes, you’ll need to make sure the sweet potatoes are cooked, mashed and cooled before adding to the cake batter. You can cook them in the microwave for about five minutes. Make sure to puncture them with a fork a few times before cooking.
Maybe, but I haven’t tested that out. If you want to experiment and that’s all you have, I’d say go for it.
Probably. I’ve only officially tested this one out as a 13×9 cake, but I see no reason that it wouldn’t work in two, 8 inch round cake pans. Just start checking for doneness about 5-10 minutes before the time listed on the recipe card.
You can, but you’ll want to omit the salt called for in the buttercream recipe.
You want to mix the cake batter until it’s well combined, but you want to be careful not to mix too long. Stop mixing as soon as the cake ingredients are well incorporated, but don’t mix for several minutes or until everything is perfectly smooth…that will produce a dense cake.
Yes, the batter for this cake is thick. You don’t want to add any extra liquid. Just try your best to spread it evenly into the pan.
If you add buttercream to the cake when it’s even a little warm, the buttercream will warm up too much and pool around the sides of the cake along the edges of your pan.
You’ll want to store this cake, well covered in the fridge as it’s topped with cream cheese frosting.
This cake is best served at room temperature. If the cake has been chilled, let it sit out of the fridge for about 20 minutes before serving so it can come closer to room temperature and soften.

Note About How I Write Recipes: I write recipes using volume (cups) measurements because here in the U.S., this is what people are more familiar with and I don’t want anyone to feel intimidated when baking. For metric measurements, click the ‘metric’ button under the ingredients in the recipe card below. The weights are converted by a program, not me, and it’s just a best guess. Please note that because I develop recipes using volume measurements, I can’t guarantee that weighing the ingredients will produce the exact same results.
