- 1 egg + 2 egg whites, room temp
- 1 1/2 tsp vanilla extract
- 1 3/4 cups + 1 tbsp cake flour
- 1/2 baking soda
- 1 1/2 tsp baking powder

For the raspberry buttercream:

- 1/2 tsp vanilla extract
- 4 tbsp raspberry reduction puree (recipe below)
- 2 tbsp heavy cream
Raspberry Reduction:
- 12 oz fresh or frozen raspberries

Instructions
- Make your vanilla cake. Prepare one 8-inch round cake pan with spray/butter and/or parchment paper. Set aside. Preheat oven to 325 degrees F.
- In a large mixing bowl with the paddle attachment, cream butter and sugar on medium-high until light and fluffy, 3-5 minutes. Add eggs one at a time, beating on medium-high in between. Add vanilla and beat on medium-high 5 minutes until batter is shiny, fluffy, and lightened in color.
- Mix together dry ingredients (cake flour, baking powder, baking soda, salt) in a separate mixing bowl. Alternate adding dry ingredients and buttermilk with the mixer on low (dry, buttermilk, dry, buttermilk, dry) until just combined. Turn the mixer off and fold in sour cream until just combined. Pour into prepared cake pan and smooth top with a spatula.
- Bake cake at 325 degrees F for 40-50 minutes, until a toothpick inserted comes out clean. Allow to come to room temperature cooling on a wire rack.
- Make your raspberry buttercream while the cake cools. In a medium saucepan, toss fresh or frozen raspberries with granulated sugar. Heat over medium, stirring consistently, until the mixture lets out liquid, becomes jammy, and reduces by about half. Remove raspberry reduction from heat and strain through a mesh sieve into a heatproof bowl. Discard solids, reserving the smooth puree for the buttercream. Set aside.
- In a large mixing bowl fitted with the paddle attachment, cream butter on medium-high until it is smooth, whipped, and lightened in color. Reduce speed to low and add sifted powdered sugar 1/2 cup at a time. until completely combined and smooth.
- Increase mixer speed to medium and add vanilla and salt. Add cooled raspberry puree and continue mixing on medium until combined. Increase the mixer speed to medium high, add heavy cream, and continue to beat the buttercream until it is smooth, fluffy, and lightened in color to a nice pink.
- Once the cake is cooled, invert onto a cake round or cake plate/stand. Decorate with raspberry buttercream and garnish with fresh raspberries and mint. Enjoy at room temperature and store in the fridge in a cake box overnight.
Notes
- Fresh or frozen raspberries will produce great results in this buttercream–I used frozen for a budget option.
- Use less raspberry reduction puree for a more subtle flavor and color in the buttercream.
- Cake will keep at room temperature for several hours, then in the fridge for 3-4 days.
