# How to Prepare:
01 - Preheat oven to 350°F 175°C. Grease and line two 9-inch 23 cm round cake pans with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt.
03 - In a large bowl, beat butter and sugar together until light and fluffy, about 3–4 minutes.
04 - Add eggs, one at a time, beating well after each addition. Mix in vanilla extract.
05 - Add dry ingredients in three additions, alternating with milk, beginning and ending with flour. Mix until just combined.
06 - Divide batter equally into two bowls.
07 - In one bowl, mix in a small amount of yellow gel food coloring until desired shade is reached.
08 - Using separate spoons, dollop alternating spoonfuls of yellow and white batters into the prepared pans, swirling gently with a skewer or knife to marble.
09 - Bake for 30–35 minutes or until a toothpick inserted at the center comes out clean.
10 - Let cakes cool in pans for 10 minutes, then turn out onto a rack to cool completely.
11 - Beat softened butter until smooth and creamy. Gradually add powdered sugar, beating well. Mix in vanilla, salt, and 2 tablespoons of milk or cream, adding more if needed for spreading consistency.
12 - Level cakes if necessary. Place one layer on a serving plate. Spread a layer of frosting on top. Place the second layer above and frost the top and sides of the cake. Decorate as desired.
