Servings: 15 slices
Ingredients
For the cake:
- ¾ cup salted butter room temperature
- ¼ cup vegetable oil
- 1 ½ cups granulated sugar
- 1 tbsp vanilla extract
- 3 eggs room temperature
- 3 cups cake flour
- 1 tsp baking powder
- ½ tsp baking soda
- ½ tsp kosher salt
- 1 ¼ cups buttermilk
For the frosting:
- 1 cup salted butter room temperature
- 4 1/2 cups powdered sugar
- ¾ cup cocoa powder
- 2-4 tbsp milk or heavy cream
- 1 tsp vanilla extract
- ¼ tsp kosher salt
- sprinkles to decorate
Instructions
For the cake:
- Grease and line a 9×13 pan and preheat the oven to 350. In the bowl of a stand mixer combine the butter, oil, granulated sugar and vanilla and beat on medium high until light and fluffy, about 4-5 minutes. Scrape down the sides of the bowl with a spatula and add the eggs, one at a time, while the mixer is on low. Mix until just incorporated.
- Add in the flour, baking powder, baking soda and salt. With the mixer on low, pour in the buttermilk and mix until everything is combined. Pour the cake batter into the prepared pan and bake for 30-35 minutes, or until completely baked through. Remove from the oven and allow to cool completely.
For the frosting:
- In the bowl of a stand mixer cream the butter, powdered sugar and cocoa powder until combined. Add in the vanilla, milk and salt and beat until smooth. Set aside until assembly.
For assembly:
- Once the cake has completely cooled, use a serrated knife to trim the top of the cake to make it level. Add about half of the frosting to the take and smooth. Add the remaining frosting to a piping bag fitted with a 1M Wilton tip. Pipe a border and top with sprinkles. Slice and enjoy!
