How to Make M&M Cupcakes Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C) and lining a 12-cup muffin tin with your favorite cupcake liners. This simple prep step ensures your cupcakes bake evenly and come out effortlessly once done.
Step 2: Combine Dry Ingredients
In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. This mixing creates an even distribution of leavening agents, giving your cupcakes a beautiful rise.
Step 3: Cream Butter and Sugar
Next, in a large bowl, beat the softened butter and granulated sugar until the mixture becomes light and fluffy. This step is crucial for incorporating air, which leads to a tender crumb.
Step 4: Add Eggs and Vanilla
Beat in the eggs one at a time, making sure each is fully incorporated before adding the next. Then, mix in the vanilla extract to infuse your batter with warmth and depth.
Step 5: Mix Sour Cream and Alternate Dry Ingredients
Stir in the sour cream until smooth. Then, gradually add the dry ingredients in three parts, alternating with the milk in two parts—start and finish with the dry ingredients. This careful mixing creates a batter that’s neither too thick nor too thin, perfect for moist cupcakes.
Step 6: Fold in Mini M&M’s
Gently fold in the mini M&M’s that have been tossed lightly in flour (this helps prevent sinking). These colorful candies add bursts of crunch and chocolate throughout every bite.
Step 7: Fill and Bake
Divide the batter evenly among the cupcake liners, filling each about three-quarters full. Bake for 18 to 20 minutes, or until a toothpick inserted in the center comes out clean. The cupcakes should be golden and springy to the touch.
Step 8: Cool and Frost
Allow the cupcakes to cool in the pan for about 5 minutes before transferring them to a wire rack to cool completely. To make the frosting, beat the butter until creamy. Gradually add powdered sugar, followed by heavy cream, vanilla extract, and a pinch of salt. Beat on high speed until light and fluffy. Frost your cooled cupcakes and crown them with extra mini M&M’s for that final pop of color and fun.
How to Serve M&M Cupcakes Recipe

Garnishes
Topping these cupcakes with a sprinkle of extra mini M&M’s adds color and texture that is immediately eye-catching. You can also add some rainbow sprinkles or a drizzle of melted chocolate for a more decadent look.
Side Dishes
Serve these cupcakes alongside a tall glass of cold milk or a hot cup of coffee or tea to balance the sweetness. Fresh fruit like strawberries or raspberries can add a refreshing contrast to the rich cupcake flavors.
Creative Ways to Present
For parties or special occasions, display your M&M cupcakes on a decorated tiered stand or arrange them in a colorful candy-themed setup. Wrapping each with a cute cupcake wrapper or placing small flags on top can elevate presentation and make your guests smile.
Make Ahead and Storage
Storing Leftovers
Store leftover M&M cupcakes in an airtight container at room temperature for up to 2 days. If you want to keep them longer, refrigerate for up to 5 days, but make sure to bring them back to room temperature before serving for the best texture.
Freezing
You can freeze unfrosted cupcakes by wrapping them tightly in plastic wrap and placing them in a freezer-safe bag for up to 3 months. When ready, thaw them at room temperature and add frosting fresh to keep the texture perfect.
Reheating
To reheat, simply warm the cupcake in the microwave for 10 to 15 seconds. Be cautious not to overheat to keep the cupcakes moist and soft. For frosted cupcakes, it’s best to let them come to room temperature rather than reheating.
FAQs
Can I use regular-sized M&M’s instead of mini M&M’s?
You can, but mini M&M’s distribute more evenly and don’t overpower each bite. Larger candies might sink more easily or dominate the texture.
What’s the secret to preventing M&M’s from sinking in the batter?
Tossing the M&M’s with a little flour before folding them into the batter helps suspend them and ensures they stay throughout your cupcakes.
Can I substitute sour cream with something else?
Yes, plain Greek yogurt or buttermilk are great alternatives that maintain moisture and tanginess without changing the cupcake’s texture.
Is it necessary to line the muffin tin with cupcake liners?
While you can bake without liners, cupcake liners make for easy removal, less mess, and a prettier presentation.
How long do M&M cupcakes stay fresh?
At room temperature, they remain fresh for about 2 days. Refrigerated, they can last up to 5 days when stored properly in an airtight container.

This M&M Cupcakes Recipe is truly a celebration in every bite and an absolute joy to bake and share. From the colorful candies that peek through the tender cake to the luscious frosting topped with more M&M’s, it’s a delightful dessert that brightens any day.
