Ingredients
For the Cake
- 1/2 tsp salt
- 1 tsp cinnamon
- 1/2 tsp nutmeg
- 1 cup unsalted butter, softened
- 2 cups granulated sugar
- 4 large eggs
- 1 tsp vanilla extract
- 2 cups mashed cooked sweet potatoes (about 2 medium)

For the Glaze

How to Make Grandma’s Famous Sweet Potato Butter Cake: How to Make an Irresistible Classic
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Prepare your Bundt pan or 9×13-inch baking dish by greasing and flouring it.
Step 2: Cream Butter and Sugar
In a large mixing bowl, cream together the unsalted butter and granulated sugar until the mixture is light and fluffy.
Step 3: Add Eggs and Vanilla
Add four large eggs one at a time, beating well after each addition. Stir in the vanilla extract until fully incorporated.
Step 4: Mix in Sweet Potatoes
Add the mashed sweet potatoes to the mixture. Blend until everything is fully combined and smooth.
Step 5: Combine Dry Ingredients
In another bowl, whisk together all-purpose flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
Step 6: Merge Wet and Dry Mixtures
Gradually add the dry ingredients to the wet mixture alternately with whole milk or buttermilk. Start with flour and end with flour—mix until just combined; do not overmix.
Step 7: Bake the Cake
Pour the batter into your prepared pan. Smooth out the top before placing it in the oven. Bake for about 50–60 minutes or until a toothpick inserted into the center comes out clean.
Step 8: Prepare the Glaze
While your cake bakes, melt butter with sugar and water in a saucepan over medium heat. Bring it to a boil while stirring constantly for about 2–3 minutes. Remove from heat; add vanilla extract.
Step 9: Glaze While Warm
Once your cake is baked and still warm, poke holes all over the top using a skewer or toothpick. Slowly pour the warm butter glaze over the cake so it absorbs completely.
Step 10: Cool Down Before Serving
Allow your cake to cool in the pan before inverting onto a plate if using a Bundt pan. If using a baking dish, slice directly from there.
