How to Make Sweet Potato Butter Cake
-
Preheat Oven: Start by setting your oven to 350°F (175°C) to ensure it’s hot and ready for baking.
-
Prep Pan: Grease a 9×13-inch pan or a bundt pan with butter or non-stick spray, so your cake slides out effortlessly after baking.
-
Mix Wet Ingredients: In a large mixing bowl, combine the mashed sweet potatoes, softened butter, granulated sugar, and sour cream. Stir until everything is well blended and creamy.
-
Incorporate Eggs: Beat in the eggs one at a time until fully incorporated, ensuring your batter has a smooth consistency and a light, airy texture.
-
Combine Dry Ingredients: In another bowl, whisk together the all-purpose flour, baking powder, baking soda, warm spices, and salt. This step helps evenly distribute the leavening agents and spices.
-
Blend Mixtures: Gradually add the dry mixture to the wet ingredients, mixing until just combined. Be careful not to overmix; a few lumps are perfectly fine!
-
Bake: Pour the batter into your prepared pan and bake for 45-60 minutes. Check for doneness by inserting a toothpick—it should come out clean when the cake is ready.

Grandma’s Famous Sweet Potato Butter Cake Recipe FAQs
How do I choose the best sweet potatoes for this cake?
Absolutely! When selecting sweet potatoes, look for firm, smooth-skinned ones without dark spots or bruises. Fresh sweet potatoes with bright orange flesh are ideal as they provide the best flavor and moisture. I recommend baking them whole at 400°F for about 45-60 minutes to enhance their natural sweetness before mashing.
How should I store my Sweet Potato Butter Cake?
To keep your cake fresh, store it covered at room temperature for up to 3 days. If you want to keep it longer, wrap it tightly in plastic wrap and refrigerate it in an airtight container for up to a week. Remember, bringing it back to room temperature before serving enhances the flavor and texture!
Can I freeze Sweet Potato Butter Cake?
Absolutely! You can freeze the unglazed cake for up to 3 months. Wrap it tightly in plastic wrap, then cover with aluminum foil to prevent freezer burn. When you’re ready to enjoy it, let it thaw in the refrigerator overnight, then bring it to room temperature before serving.
What should I do if my cake turns out dry?
To ensure a moist cake, it’s essential to measure your flour correctly—always spoon it into the measuring cup rather than scooping directly, which can compact the flour. Additionally, avoid overmixing the batter; a few lumps are okay. If you find your cake is already dry, a drizzle of warm glaze or a scoop of whipped cream can help bring back some moisture.
Is this cake suitable for people with gluten allergies?
Yes, indeed! You can easily make this Sweet Potato Butter Cake gluten-free by substituting the all-purpose flour with a 1:1 gluten-free flour blend. Just ensure that all other ingredients, especially baking powder, are also certified gluten-free. Enjoy baking without worry!
