Homemade Funfetti Cupcakes Made Stepwise

Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures that the cupcakes bake evenly and rise beautifully. Line a cupcake pan with liners while you wait for the oven to heat up.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, and Kosher salt. This step helps to evenly distribute the leavening agent throughout the flour, ensuring your cupcakes rise perfectly.
Step 3: Cream Butter and Sugar
In a large mixing bowl, use an electric mixer to cream together the room temperature unsalted butter and granulated sugar until the mixture is light and fluffy. This should take about 3-5 minutes.
Step 4: Add Eggs and Vanilla
Add the eggs one at a time, mixing well after each addition. Then, add the vanilla extract and continue to mix until fully incorporated.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry mixture to the wet mixture, alternating with the whole milk. Start and end with the dry ingredients, mixing just until combined. Be careful not to overmix, as this can lead to dense cupcakes.
Step 6: Fold in the Sprinkles
Gently fold in the rainbow sprinkles using a spatula. This ensures they are evenly distributed without breaking them apart.
Step 7: Fill the Cupcake Liners
Scoop the batter into the prepared cupcake liners, filling each about two-thirds full. This allows room for the cupcakes to rise without overflowing.
Step 8: Bake
Place the cupcake pan in the preheated oven and bake for 15-18 minutes, or until a toothpick inserted into the center comes out clean. Keep an eye on them to avoid overbaking.
Step 9: Cool the Cupcakes
Once baked, remove the cupcakes from the oven and let them cool in the pan for about 5 minutes. Then, transfer them to a wire rack to cool completely.
Step 10: Make the Frosting
In a large mixing bowl, beat the room temperature unsalted butter until smooth. Gradually add in the powdered sugar, mixing on low speed. Once combined, add the milk and vanilla extract, then mix until the frosting is creamy and fluffy.
Step 11: Frost the Cupcakes
Once the cupcakes are completely cool, use a spatula or piping bag to frost each cupcake generously. Top with additional rainbow sprinkles for that extra festive touch!
Holiday-Friendly Variations

- Red Velvet Funfetti: Replace half of the flour with cocoa powder and add red food coloring for a festive twist.
- Chocolate Funfetti: Add 1/3 cup of cocoa powder to the dry ingredients for a chocolatey version.
- Seasonal Sprinkles: Use holiday-themed sprinkles for occasions like Christmas or Halloween.
- Flavored Frosting: Experiment with different extracts like almond or peppermint in the frosting for unique flavors.
Notes from the Test Kitchen
To ensure your cupcakes are perfectly moist and fluffy, make sure all your ingredients are at room temperature before mixing. This allows for better emulsification and a more cohesive batter. If you prefer a less sweet frosting, reduce the amount of powdered sugar and increase the milk slightly until you reach your desired consistency.

This Homemade Funfetti Cupcakes recipe is one to keep on hand for birthdays, celebrations, or even just a sweet treat for yourself.
