Ingredients
For the Purple Velvet Cake:
- 2 ½ cups all-purpose flour
- 2 tbsp cocoa powder
- 1 tsp baking soda
- ½ tsp salt
- 1 cup unsalted butter, softened
- 1 ¾ cups granulated sugar
- 4 large eggs
- 1 cup buttermilk
- 2 tsp vanilla extract
- 1 tbsp white vinegar
- Purple gel food coloring (as needed)
For the Creamy Vanilla Frosting:
- 1 cup unsalted butter, room temperature
- 4 cups powdered sugar
- 2 tbsp heavy cream
- 1 tbsp vanilla extract
- Pinch of salt
Instructions
Step 1: Prepare the Cake Layers
- Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans.
- In a medium bowl, sift together the flour, cocoa powder, baking soda, and salt.
- In a large bowl, cream the butter and sugar until light and fluffy.
- Beat in the eggs, one at a time. Then mix in the vanilla extract and vinegar.
- Gradually add the dry ingredients, alternating with buttermilk, beginning and ending with flour mixture.
- Add purple food coloring until the desired hue is achieved.
- Divide the batter evenly between pans. Bake for 30–35 minutes or until a toothpick comes out clean.
- Let cakes cool in the pan for 10 minutes, then transfer to wire racks to cool completely.
Step 2: Make the Creamy Vanilla Frosting
- Beat the butter until smooth and creamy.
- Add powdered sugar one cup at a time, mixing well.
- Add vanilla, heavy cream, and a pinch of salt. Beat until fluffy (about 3–4 minutes).
- If too thick, add a little more cream; if too thin, add more powdered sugar.

Step 3: Assemble the Cake
- Level the cakes with a serrated knife if needed.
- Place one cake layer on a stand and spread a thick layer of frosting.
- Add the second layer and frost the top and sides.
- Decorate with edible glitter, purple sprinkles, or piped rosettes.
