Recipe Ingredients

Here are the amazing ingredients that make our Sweet Potato Cake with Cinnamon Frosting so special.

Sweet Potatoes: These vibrant orange beauties are the heart of our sweet potato cake recipe! They provide natural sweetness, incredible moisture, and that signature earthy flavor.

How to Make Sweet Potato Cake with Cinnamon Frosting

To make sure your Sweet Potato Cake with Cinnamon Frosting turns out perfectly every time, here are some key tips. See the full recipe below for all the details.

1. Prepare Your Batter

After combining all the cake batter ingredients, mix only for the recommended 2 minutes. Overmixing can develop the gluten too much, leading to a tougher, less tender cake. When adding the mashed sweet potato to the batter, make sure to use exactly 1 1/2 cups. Too much or too little can affect the cake's texture and moisture.

2. Bake and Cool

Allow the cake to cool for the full 1 hour 30 minutes (or until completely cool to the touch) before applying the frosting. If the cake is warm, the frosting will melt and slide off, making a mess.

3. Frost and Decorate

For a smooth and even layer of frosting, an offset spatula is your best friend. It helps you spread the frosting easily across the top of the cake. Drizzle with caramel and sprinkle with pecans to finish.

How to Store Sweet Potato Cake with Cinnamon Frosting

Store the finished cake loosely covered in the refrigerator. This helps keep it fresh and moist, especially with the creamy frosting. Store for up to 4 days.
