Ingredients

For the Cupcakes:

• 1 ½ tsp baking powder
• ¼ tsp baking soda
• ¼ tsp salt
• ½ cup (115 g) unsalted butter, softened
• ¾ cup (150 g) granulated sugar
• 2 large eggs, room temperature
• 2 tsp pure vanilla extract
• ½ cup (120 ml) buttermilk, room temperature
• ¼ cup (60 ml) whole milk
• ⅓ cup (60 g) rainbow sprinkles (use “jimmies” type, not nonpareils)

For the Vanilla Buttercream Frosting:

• 1 cup (230 g) unsalted butter, softened
• 3 cups (375 g) powdered sugar
• 2 tbsp heavy cream (or milk)
• 1 ½ tsp pure vanilla extract
• Pinch of salt
• Extra rainbow sprinkles for decorating

Step-by-Step Preparation Method

Step 1: Preheat and Prep

1. Preheat your oven to 350°F (175°C).
2. Line a 12-cup muffin tin with cupcake liners.

Step 2: Mix Dry Ingredients

1. In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
2. Set aside.

Step 3: Cream Butter and Sugar

1. In a large mixing bowl, using an electric mixer, beat the butter and sugar together on medium speed for 2–3 minutes until light and fluffy.
2. Add eggs one at a time, beating well after each addition.
3. Mix in the vanilla extract.

Step 4: Combine Wet and Dry Ingredients

1. With the mixer on low speed, add half of the dry ingredients, then buttermilk, followed by the rest of the dry mixture.
2. Pour in the milk and mix until just combined — don’t overmix!
3. Gently fold in the rainbow sprinkles using a spatula.

Step 5: Fill and Bake

1. Divide the batter evenly among the cupcake liners (about ⅔ full).
2. Bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean.
3. Allow cupcakes to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Step 6: Make the Buttercream Frosting

1. In a large bowl, beat butter until smooth and creamy (about 2 minutes).
2. Gradually add powdered sugar, 1 cup at a time, beating on low until incorporated.
3. Add heavy cream, vanilla, and salt, then beat on high for 2–3 minutes until light and fluffy.
4. If the frosting is too thick, add a little more cream. If too thin, add more powdered sugar.

Step 7: Frost and Decorate

1. Once the cupcakes are completely cool, frost them using a piping bag fitted with a star tip (or simply spread frosting with a spatula).
2. Finish by sprinkling extra rainbow sprinkles on top.

How to Serve

• Serve these colorful cupcakes at birthday parties, baby showers, or picnics.
• They pair beautifully with cold milk, coffee, or a scoop of vanilla ice cream.
• For a festive display, place them on a cake stand and top with colorful candles or edible glitter.

Recipe Tips

• Use “jimmies” sprinkles — they hold color when baked, unlike nonpareils, which bleed.
• Room temperature ingredients ensure a smoother batter and even baking.
• Do not overmix once sprinkles are added, or colors may streak.
• Cool completely before frosting — warm cupcakes will melt the buttercream.
• Add a tiny pinch of almond extract for an extra bakery-style flavor.

Recipe Variations

1. Chocolate Funfetti Cupcakes: Replace ¼ cup of flour with cocoa powder for a chocolatey twist.
2. Lemon Funfetti Cupcakes: Add 1 tbsp lemon zest and replace buttermilk with lemon-flavored yogurt for a citrus touch.
3. Confetti Cake Version: Double the recipe and bake in a 9x13-inch pan for a colorful sheet cake.
4. Gluten-Free Funfetti Cupcakes: Use a 1:1 gluten-free flour blend.
5. Vegan Version: Replace eggs with ½ cup applesauce and butter with vegan margarine or coconut oil.
6. Holiday-Themed: Use red and green sprinkles for Christmas, or pastel for Easter!

Freezing and Storage

• Room Temperature: Store in an airtight container for up to 2 days.
• Refrigerator: Keep refrigerated (especially if frosted) for up to 5 days.
