Preparation Steps: How to Make It

Creating this sweet potato cinnamon roll cake is an enjoyable process. Let’s take it step-by-step!

Step 1: Prepping the Sweet Potatoes

The first thing ya wanna do is cook your sweet potatoes. You can steam them or bake them until they’re tender. Once they’re cool enough to handle, mash ‘em up real good. You need about one cup of mashed sweet potatoes for this recipe, so make sure you measure it out.

Step 2: Making the Cake Batter

In a large bowl, mix together the mashed sweet potatoes, granulated sugar, brown sugar, vegetable oil, eggs, and vanilla extract. Whisk until everything is well blended and smooth.

In a separate bowl, whisk together your dry ingredients: flour, baking powder, baking soda, cinnamon, and salt. Gradually add the dry mixture to the wet mixture until just combined. Avoid overmixing; we want it light and fluffy!

Step 3: Preparing the Cinnamon Filling

In a small bowl, combine the brown sugar and ground cinnamon. Pour in the melted butter, stirring until it resembles a slurry. This mixture is what’ll give your cake those delicious swirls of cinnamon goodness.

Step 4: Assembling the Cake

Grease a 9×13 inch baking pan. Pour half of the cake batter into the prepared pan. Then, drizzle half of the cinnamon filling over the top. Use a knife to swirl it gently into the batter.

Pour the remaining cake batter on top and then drizzle the rest of that cinnamon filling. Again, swirl it lightly with a knife. Don’t go too deep; you want swirls, not a mixed-up mess!

Step 5: Baking

Bake the cake in a preheated oven at 350°F (175°C) for 30–35 minutes. The cake is done when a toothpick inserted in the center comes out clean.

Step 6: Make the Frosting

While the cake’s baking, whip up that delightful cream cheese frosting. In a bowl, beat the softened cream cheese and butter until smooth. Add in the vanilla extract and mix again. Gradually introduce powdered sugar, adding milk as necessary to achieve your desired consistency.

Step 7: Frosting the Cake

Once the cake has cooled for about 10 minutes, spread the cream cheese frosting over the top. Allow it to cool completely before cutting into squares. Serve, and enjoy every bite as the flavors dance on your palate!
