🛒 Ingredients

All-purpose flour	2 ½ cups
Baking powder	2 ½ teaspoons
Salt	½ teaspoon
Unsalted butter (softened)	1 cup
Granulated sugar	1 ¾ cups
Eggs	4 large

For the Frosting

Ingredient	Quantity
Unsalted butter (softened)	1 cup
Powdered sugar	4 cups
Vanilla extract	2 teaspoons
Heavy cream	3-4 tablespoons
Gel food coloring (optional for rainbow swirls)	As needed

💡 Tip: Use gel food coloring instead of liquid food coloring. Gel colors provide more vibrancy without altering the consistency of the batter!

🛠 Equipment Needed

Large mixing bowls 🥣 (for wet and dry ingredients)
Hand or stand mixer 🎛 (for a smooth batter and frosting)
Cupcake liners 🧁 (to prevent sticking)
Muffin tin (standard 12-cup size)
Spatula (for folding and mixing batter)
Piping bags & tips (for frosting)
Toothpicks (to create swirl effects if desired)

Using a stand mixer will make creaming the butter and sugar easier, resulting in a light and fluffy texture. But don’t worry—a hand mixer works just as well!

👩‍🍳 Step-by-Step Instructions

1️⃣ Preparing the Batter

Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
In a bowl, whisk together flour, baking powder, and salt. Set aside.
In a separate large bowl, beat the butter and sugar until light and fluffy (about 2 minutes).
Add the eggs one at a time, mixing well after each. Stir in the vanilla extract.
Gradually add the dry ingredients and milk, alternating between the two, starting and ending with the dry mix. Mix until smooth.

2️⃣ Coloring the Batter

Divide the batter equally into 6 bowls.
Add a few drops of gel food coloring to each bowl (red, orange, yellow, green, blue, and purple). Stir until fully combined.
Layer the colored batters into each cupcake liner, starting with purple at the bottom and ending with red on top. Use a spoon for each color, adding small amounts to create layers.
If you want a swirled effect, use a toothpick to gently drag through the layers.

3️⃣ Baking the Cupcakes

Bake for 18-20 minutes or until a toothpick inserted into the center comes out clean.
Allow the cupcakes to cool completely before frosting.

4️⃣ Making the Frosting

Beat butter until creamy, then gradually add powdered sugar.
Mix in vanilla extract and heavy cream until light and fluffy.
If desired, divide the frosting into multiple bowls and color each one.
Transfer the frostings into a piping bag to create a rainbow swirl effect when decorating.

5️⃣ Frosting and Decorating

Pipe frosting onto each cupcake using a swirl motion.
Garnish with rainbow sprinkles or edible glitter for extra magic!
