Ingredients

3 cups all-purpose flour sifted
2 cups granulated sugar extra fine
1.5 cups unsalted butter softened to room temperature
5 large eggs room temperature
1 cup whole milk slightly warmed
1 tbsp baking powder
2 tsp vanilla extract pure Madagascar vanilla preferred
0.5 tsp salt fine sea salt

Notes

For the best results, use gel food coloring rather than liquid to achieve bright colors without thinning the batter. The cake can be made a day in advance; store it in an airtight container at room temperature. For clean slices, dip your knife in hot water and wipe dry between each cut.
