Instructions
To make the cake
- Preheat oven to 350 degrees F and grease 2 8-inch round baking pans, line the bottom of each cake pan with parchment paper to form a circle to fit the bottoms. Set aside.
- In a medium mixing bowl, whisk together the flour, baking powder, and baking soda.
- In a large mixing bowl with an electric hand mixer or in the bowl of a stand mixer with a paddle attachment, cream together the butter and sugar until light, fluffy, and pale for a few minutes.
- Add in the oil and vanilla bean paste, mix until fully combined, smooth and mixture is creamy. Add in the whole egg and egg yolk one at a time until incorporated.
- Rotate between adding the buttermilk and flour mixture in 3 increments. Make sure the cake batter is combined, but do not over-mix.
- Pour the cake batter into the prepared cake pans. Bake for 40-45 minutes or until a tooth pick inserted comes out clean and the tops are a light golden brown. Let the cakes cool on a cooling rack for about 30 minutes. Carefully run a butter knife along the edge of the cake pan and carefully flip it over on a cooling rack to cool for another 10-15 minutes or until cooled completely.
To make the frosting
- In a separate bowl, beat together the softened butter with an electric mixer or stand mixer until light and fluffy. Mix on low speed and gradually increase the speed when adding the powdered sugar, one cup at a time. Add in the vanilla and buttermilk and continue to beat on high speed until creamy and fluffy, about 1-2 minutes. Be sure to scrape the sides of the bowl with a rubber spatula. Add more powdered sugar if frosting is too thin, and more buttermilk if frosting is too thick.
To frost the cake
- Place one layer of the cake on the bottom of a cake stand or cake plate. Spread a thick layer of frosting to cover the top, then place the second layer on top. Spread frosting all over the top and sides of the cake. Make the frosting smooth or make swirls with a spoon. Decorate with rainbow sprinkles (optional) and enjoy!
