3 cups powdered sugar
1 teaspoon vanilla extract
2–3 tablespoons heavy cream or milk

-Step-by-Step Instructions
1. Prepare the Cupcake Batter
1. Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
2. In a bowl, whisk together flour, baking powder, and salt.
3. In another bowl, beat the butter and sugar until light and fluffy (about 2 minutes).
4. Add the eggs, one at a time, beating well after each addition.
5. Mix in the vanilla extract.
6. Gradually add the dry ingredients, alternating with milk, mixing just until combined.
-2. Divide and Color the Batter
1. Divide the batter evenly into 6 small bowls.
2. Add a few drops of gel food coloring to each bowl and mix until vibrant.
3. Using a spoon, layer small amounts of each colored batter into each cupcake liner, one at a time.
4. Use a toothpick or skewer to gently swirl the colors for a marbled effect.
-3. Bake the Cupcakes
1. Bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean.
2. Let cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
-4. Make the Vanilla Buttercream Frosting
1. In a bowl, beat butter until smooth and creamy.
2. Gradually add powdered sugar, mixing on low speed.
3. Stir in vanilla extract and 2 tablespoons of cream/milk.
4. Beat on high speed for 3 minutes until light and fluffy. If too thick, add more cream/milk 1 teaspoon at a time.
-5. Create the Rainbow Swirl Frosting (Optional)
