Step‑by‑Step Instructions for Sweet Potato Upside Down Cake
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While the oven heats up, generously grease a 9-inch round cake pan with 2 tablespoons of softened butter. For easy cake removal, line the bottom with parchment paper. This initial preparation sets the stage for a beautifully baked Sweet Potato Upside Down Cake.
Step 2: Cream Butter and Sugar
In a large mixing bowl, cream together 3/4 cup of softened butter and 3/4 cup of granulated sugar until the mixture is light and fluffy—around 4–5 minutes using an electric mixer. The fluffy texture indicates you’re on the right path for the cake batter. This step ensures richness and sweetness throughout your delicious cake.
Step 3: Incorporate Oil
Slowly add in 1/4 cup of vegetable oil to the creamed mixture, blending well until fully incorporated. This addition will enhance the moistness of your Sweet Potato Upside Down Cake. Mix for an additional minute until you notice a smooth, creamy consistency—perfect for a tender cake crumb.
Step 4: Whisk Dry Ingredients
In a separate bowl, whisk together the dry ingredients: 2 cups of all-purpose flour, 1 teaspoon baking powder, 1/2 teaspoon baking soda, 1/4 teaspoon salt, 1 teaspoon allspice, 1 teaspoon ginger, and 1 tablespoon chopped rosemary. This step locks in the warm spices that beautifully complement the sweet potatoes, providing a flavorful base for your batter.
Step 5: Prepare Wet Ingredients
In another medium bowl, combine 2 large eggs, 1 cup of buttermilk, 1/4 cup of molasses, and 1 teaspoon of vanilla extract. Whisk until the mixture is uniformly combined. Adding these wet ingredients creates a liquid blend that will contribute to the moistness and flavor depth of your Sweet Potato Upside Down Cake.
Step 6: Combine Mixtures
Gradually add the dry ingredients to the creamed butter mixture, alternating with the wet ingredients, starting and ending with the dry. Mix just until combined to avoid overmixing, which could result in a dense cake. The batter should be thick yet smooth, signaling it’s ready to be poured into the pan.
Step 7: Prepare Sweet Potatoes
Peel and slice 2 cups of sweet potatoes thinly (no more than 1/4 inch thick). Arrange the slices evenly across the bottom of the prepared cake pan. This creates a stunning and caramelized topping that will shine through once the cake is flipped—an essential step for your Sweet Potato Upside Down Cake.
Step 8: Pour Batter and Bake
Gently pour the prepared batter over the arranged sweet potatoes in the cake pan. Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. This visual cue is key to achieving a perfectly baked dessert.
Step 9: Cool and Flip the Cake
Once out of the oven, let your Sweet Potato Upside Down Cake cool in the pan for about 10 minutes. This resting time is crucial for preventing breakage. After cooling, carefully invert the cake onto a serving plate, allowing the caramelized sweet potatoes to be the masterpiece of your baking effort.

Make Ahead Options
These Sweet Potato Upside Down Cakes are perfect for busy home cooks who love a tasty treat without the last-minute rush! You can prepare the cake batter up to 24 hours in advance and store it in the refrigerator; just be sure to cover it tightly to maintain its freshness. Additionally, slice and arrange your sweet potatoes in the pan, then refrigerate them overnight to keep them from browning. When you’re ready to bake, simply pour the chilled batter over the sweet potatoes and bake as directed. This way, you’ll enjoy a warm, comforting dessert that tastes just as delicious as if you made it fresh that same day!
