Step-by-Step Instructions for Sweet Potato Butter Cake
Step 1: Preheat Oven and Prepare Pan
Begin by preheating your oven to 350°F (175°C). While the oven heats up, generously grease and flour a Bundt pan or baking dish to ensure your Sweet Potato Butter Cake releases easily after baking. This preparation is crucial for achieving that perfect, beautiful finish!
Step 2: Cream Butter and Sugar
In a large mixing bowl, use an electric mixer to cream together 1 cup of softened unsalted butter and 2 cups of granulated sugar until the mixture becomes light and fluffy, about 3-5 minutes. The creamy texture indicates that you’ve incorporated enough air, which will help the cake rise beautifully.
Step 3: Incorporate Eggs and Sweet Potatoes
Add 4 room temperature eggs to the butter and sugar mixture, one at a time, mixing well after each addition. Then gently fold in 2 cups of mashed sweet potatoes and 1 tablespoon of vanilla extract until the batter is smooth and well combined, creating a delightful flavor base for your cake.
Step 4: Mix Dry Ingredients
In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, 1 teaspoon of baking soda, 1/2 teaspoon of salt, 1 teaspoon of ground cinnamon, and 1/2 teaspoon of nutmeg. This step ensures your dry ingredients are evenly distributed, which is key for giving the Sweet Potato Butter Cake a consistent texture as it bakes.
Step 5: Combine Wet and Dry Mixtures
Gradually add the dry ingredients to the wet mixture, alternating with 1 cup of milk or buttermilk, starting and ending with flour. Mix gently until just combined. Take care not to overmix; this will help keep your cake tender and fluffy, allowing the moist sweetness of the sweet potatoes to shine through.
Step 6: Bake the Cake
Pour the batter into the prepared pan, spreading it evenly. Place it in the preheated oven and bake for 50 to 60 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs. The golden color and aroma wafting from the oven will indicate it’s nearly time to enjoy your delicious Sweet Potato Butter Cake.
Step 7: Prepare the Butter Glaze
While the cake is baking, prepare the butter glaze by combining 1/2 cup of unsalted butter, 1 cup of granulated sugar, and 1/4 cup of water in a small saucepan. Bring the mixture to a boil, stirring constantly to prevent scorching. Once it reaches a boil, remove it from the heat and stir in 1 teaspoon of vanilla extract for added flavor.
Step 8: Glaze the Cake
Once the cake is out of the oven, poke holes all over its warm surface using a toothpick or fork. Pour the warm butter glaze generously over the top, allowing it to soak into the cake for added moisture and richness. This delightful addition will create a beautiful glaze that enhances the Sweet Potato Butter Cake’s flavor profile.
Step 9: Cool and Serve
Let the cake cool in the pan for about 20 minutes before transferring it to a wire rack to cool completely. This step is essential to maintain the integrity of the glaze and ensures that each slice of your Sweet Potato Butter Cake remains beautifully moist and flavorful when served.
How to Store and Freeze Sweet Potato Butter Cake
Room Temperature: Store the cake at room temperature for up to 3 days, covered with a cake dome or plastic wrap to keep it fresh and moist.
Fridge: If you want to extend its life, refrigerate the cake for up to a week. Just be sure to wrap it tightly to prevent it from drying out.

Reheating: To enjoy the cake warm, microwave each thawed slice for 15-20 seconds or until heated through. This enhances the delicious flavors of your Sweet Potato Butter Cake!
