How to Make It
Heat the Oven & Prep the Pan
Warm your oven to 350°F and line a 15×10-inch jelly roll pan with foil or parchment. Press it neatly into the corners so your cake lifts cleanly and stays soft and even.
Cream the Butter & Sugar
In your mixer bowl, beat the butter and sugar until the mixture turns pale and airy about 3 minutes. It should look like fluffy sunshine. This is what gives the cake its soft crumb.
Add the Vanilla & Eggs
Add the vanilla, then the eggs one at a time. Let each one disappear fully before adding the next. The batter should feel silky and smooth.
Whisk the Dry
Ingredients
In a separate bowl, whisk the flour and baking powder. This little step keeps the cake even and prevents pockets of leavener from hiding in the batter.
Combine Wet & Dry
Add the flour mixture and milk in alternating rounds:
- Half the flour
- Half the milk
- One-third of the flour
- Remaining milk
- Last bit of flour
Beat only until the flour vanishes no more. Overmixing is the enemy of tenderness.
Fold in the M&M’s Minis
With a gentle hand and a soft spatula, fold in the M&M’s minis. Just a few strokes keeps their color bright and prevents bleeding.
Bake the Cake
Pour the batter into your prepared pan. Smooth the top, then bake for about 20 minutes until golden and a toothpick comes out clean. Let the cake cool completely before turning it out onto a wire rack.
Make the Frosting
Beat the butter and cream cheese together until silky. Slowly add powdered sugar, ½ cup at a time, letting it melt into the mixture before adding more.
Turn the speed up and whip for 2–3 more minutes until fluffy. Add a few drops of cream if needed. Fold in the M&M’s minis until the frosting looks fun and speckled.
Assemble the Cake
Slice the cooled cake into three equal pieces. Place the first layer onto a serving platter.
Spread half the frosting across the first layer like snowy peaks. Add the second layer, then spread the remaining frosting. Finish by placing the third layer on top.
Refrigerate for about an hour to let the layers settle and firm.
Make the Ganache
Heat the cream in a small saucepan just until it begins to boil. Pour it over the chopped chocolate, wait 30 seconds, and then stir until it becomes smooth, glossy, and irresistible.
Let the ganache cool until slightly thickened, then pour it over the chilled cake. Let it drip naturally, or gently guide it with the back of a spoon.
Decorate with as many M&M’s as your heart feels like this is the fun part.
Chill for 2–3 hours, then let the cake sit 20–30 minutes at room temp before slicing.
M&M’s Cake with Cream Cheese Frosting and Chocolate
Equipment
- Basic baking equipment Oven, 15×10 inch jelly roll pan, parchment or foil, mixing bowls, stand mixer or hand mixer, spatula, small saucepan, sharp knife.
Ingredients
- 3/4 cup butter, room temperature
- 3/4 cup sugar
- 1 teaspoon vanilla extract
- 3 eggs, room temperature
- 2 1/4 cups all-purpose flour
- 1 1/2 teaspoons baking powder
- 3/4 cup milk, room temperature
- 3/4 cup M&M’s minis milk chocolate baking bits
- 6 tablespoons butter, room temperature (for frosting)
- 4 tablespoons cream cheese, room temperature
- 2 3/4 cups powdered sugar
- few drops of heavy cream or whole milk
- 1 cup M&M’s minis milk chocolate baking bits (for frosting)
- 4 ounces baking chocolate (about 60%), chopped
- 1/2 cup heavy cream (for ganache)
- 1 to 1 1/2 cups M&M’s to decorate
Instructions
- Heat the oven to 350°F (175°C). Line a 15×10 inch jelly roll pan with aluminum foil or parchment paper, pressing it into the corners. Lightly grease if desired and set aside.
- In the bowl of a stand mixer, add the room temperature butter and sugar. Using the paddle attachment, beat on low to medium speed until the mixture is light and fluffy, about 3 minutes, scraping down the bowl as needed.
- Add the vanilla extract, then the eggs one at a time, beating well after each addition until each egg is fully incorporated and the batter is smooth.
- In a separate bowl, whisk together the all-purpose flour and baking powder. This helps evenly distribute the leavener throughout the batter.
- Add the flour mixture and the milk to the batter in alternating additions: start with about half of the flour, then half of the milk, then another portion of the flour, the remaining milk, and finally the rest of the flour. Mix on low speed just until no dry flour remains. Do not overmix.
- Using a spatula, gently fold in the M&M’s minis baking bits. Give the batter just a few folds to distribute the candies without letting the colors bleed too much into the batter.
- Pour the batter into the prepared jelly roll pan and spread it evenly. Bake in the preheated oven for about 20 minutes, or until the top is golden and a toothpick inserted in the center comes out clean. Remove from the oven and let the cake cool completely in the pan before inverting onto a wire rack.
- To make the frosting, place the room temperature butter and cream cheese in a mixing bowl. Using the paddle attachment, beat on low speed until smooth, combined, and creamy, about 2 to 3 minutes.
- With the mixer on the lowest speed, gradually add the powdered sugar about 1/2 cup at a time, letting each addition mix in before adding more. Once all the powdered sugar has been added, increase the speed to medium and beat for another 2 to 3 minutes until the frosting is fluffy. If the frosting seems too stiff, add a few drops of heavy cream or milk until you reach the desired consistency.
- Using a spatula, fold in the M&M’s minis baking bits until they are evenly distributed throughout the frosting.
- Once the cake is completely cool, cut it into 3 equal rectangular pieces. Place the first layer onto a serving platter. Spread half of the M&M’s cream cheese frosting evenly over the top. Place the second layer on top and spread the remaining frosting over it. Finish by placing the third cake layer on top. Transfer the assembled cake to the refrigerator and chill for about 1 hour to set.
- While the cake chills, make the ganache. Place the chopped baking chocolate in a heatproof bowl. In a small saucepan, heat the heavy cream just until it reaches a boil. Pour the hot cream over the chocolate and let it sit undisturbed for about 30 seconds, then stir until the chocolate is fully melted and the mixture is smooth and shiny.
- Let the ganache sit at room temperature until it thickens slightly but is still pourable. Remove the chilled cake from the refrigerator and pour the ganache over the top, allowing it to drip down the sides. You can let it flow naturally or gently spread it with a spatula or the back of a spoon.
- Decorate the top of the cake with 1 to 1 1/2 cups of M&M’s. Refrigerate the cake for at least 2 to 3 hours to fully set. Before serving, let the cake stand at room temperature for 20 to 30 minutes, then slice and enjoy.
