Instructions
To make the cake

- Divide batter into 2-6 parts (depending on how many colors you want), and dye each part with gel food coloring. Then, create a swirl by pouring one color after another into the center in 2 tbsp increments (see blog post for details).
- Pour into greased cake pans. Bake 25-30 minutes at 350F, until a toothpick comes out clean
- Allow cake to cool while you work on your frosting.
- Before frosting, level your cake layers. Optional: cut layers in half to create 4 layers.
To make the frosting
- Add butter into stand mixer and beat on medium-low speed until butter is whipped.
- Mix in vanilla extract, almond extract, and salt and beat until mixture is smooth, scraping down the sides as needed.
- Add powdered sugar 1/2 cup at a time, until fully incorporated.
- Add milk or cream and mix on medium speed to combine.
- To thicken thin frosting, add powdered sugar. If frosting is too thick, add a more milk or cream 1 tsp at a time.
