Ingredients You’ll Need

The magic of this M&M’S Peanut Butter Cake with Peanut Butter Frosting Recipe starts with simple, everyday ingredients that come together beautifully to create layers of flavor and irresistible texture. Each component plays a crucial role—whether it’s the creaminess of butter, the tang of vanilla yogurt, or the playful crunch of those iconic Peanut Butter M&M’S.

• Butter (1 cup, room temperature): Provides richness and helps create a tender crumb in the cake and smooth frosting texture.
• Sugar (1 cup): Sweetens the cake and aids in moisture retention for softness.
• Vanilla Extract (1 teaspoon): Adds warm, aromatic depth to the flavor profile.
• Eggs (3): Bind the ingredients together and contribute to the cake’s structure.
• Vanilla Yogurt (1 cup, drained): Keeps the cake moist and gives a subtle tang to balance the sweetness.
• All-Purpose Flour (2 cups): The foundation of the cake, providing structure.
• Baking Powder (2 teaspoons): Ensures the cake rises perfectly light and fluffy.
• Salt (pinch): Enhances all the flavors, especially balancing the sweetness.
• Peanut Butter M&M’S (3/4 cup, roughly chopped): Adds bursts of crunchy peanut butter candy nuggets throughout the cake.
• Butter (1 cup, room temperature): For the frosting—a creamy peanut butter base.
• Creamy Peanut Butter (2 cups): Provides that unmistakable rich peanut butter flavor in the frosting.
• Powdered Sugar (5 cups): Gives the frosting its sweetness and thick, spreadable consistency.
• Heavy Cream (1/4 cup, optional): Whipped into the frosting for extra lightness and fluffiness.

How to Make M&M’S Peanut Butter Cake with Peanut Butter Frosting Recipe

Step 1: Prepare Baking Pans and Preheat Oven

Start by heating your oven to 350°F (175°C). Grease two 9-inch round cake pans thoroughly and line the bottoms with parchment paper. This preparation prevents sticking and ensures your cakes come out perfectly shaped and easy to remove.

Step 2: Cream Butter and Sugar

Using a stand mixer with a paddle attachment, beat the softened butter and sugar together on low speed. Continue mixing until the combination turns light and creamy—this usually takes about 3 minutes and is essential for a fluffy cake texture.

Step 3: Add Vanilla and Eggs

Pour in the vanilla extract, then add the eggs one at a time, making sure each egg is fully incorporated before adding the next. This slow incorporation helps create a smooth, cohesive batter without lumps.

Step 4: Combine Yogurt and Dry Ingredients

Next, blend in the drained vanilla yogurt gently. Then, gradually add the sifted flour, baking powder, and salt in two or three batches, mixing only until just combined. Over-mixing can make the cake dense, so patience here pays off.

Step 5: Fold in M&M’S

Take your spatula and carefully fold in the chopped Peanut Butter M&M’S. This step evenly distributes those colorful candy chunks, offering delightful bursts of peanut butter flavor and texture throughout the cake.

Step 6: Bake the Cakes

Divide the batter evenly between the prepared pans. Bake for 22 to 25 minutes or until a toothpick inserted into the center comes out clean. This precise timing ensures a moist interior with a delicate crumb.

Step 7: Cool the Cake Layers

Allow the cakes to cool fully in their pans on wire racks. Cooling them completely before frosting prevents the frosting from melting and sliding off, keeping the layers neat and beautiful.

Step 8: Prepare the Frosting

In a clean bowl, beat the butter and creamy peanut butter together until the mixture is silky smooth. This is the luscious base for your frosting that brings the peanut butter theme full circle.

Step 9: Add Powdered Sugar

Gradually mix in the powdered sugar, about half a cup at a time, beating gently after each addition. The result is a thick and creamy frosting that’s just sweet enough without overpowering the peanut butter taste.

Step 10: Incorporate Heavy Cream (If Using)

If you want an extra fluffy frosting, whisk in the heavy cream. Whip on low speed initially, increasing gradually over 5 minutes to introduce just the right amount of air and lightness.

Step 11: Assemble the Cake

Set one cake layer on your serving plate, optionally inside a cake ring. Spread half the frosting evenly on top, ensuring every bite has creamy peanut butter goodness.

Step 12: Add the Second Layer and Frost

Gently place the second layer on top, pressing lightly to secure, then spread the remaining frosting over the top. Tighten the cake ring if using to keep everything perfectly in place while chilling.

Step 13: Decorate and Set

Top your masterpiece with additional Peanut Butter M&M’S or a fun mix of peanut and regular M&M’S for a colorful finish. Chill the cake in the fridge for at least 2 to 3 hours to let the frosting set completely before slicing.

How to Serve M&M’S Peanut Butter Cake with Peanut Butter Frosting Recipe

Garnishes

A sprinkle of extra Peanut Butter M&M’S on top adds wonderful texture and boost of peanut butter punch. For an elegant touch, toss on some crushed peanuts or a drizzle of melted peanut butter.

Side Dishes

This cake pairs fabulously with a scoop of vanilla ice cream or a dollop of freshly whipped cream to balance the richness. Fresh berries also add a bright pop of acidity that complements the luscious peanut butter flavor.

Creative Ways to Present

Consider serving the cake on a vibrant cake stand decorated with scattered M&M’S for a playful vibe. You can also cut the cake into mini squares and serve on a platter for bite-sized indulgence at parties.

Make Ahead and Storage

Storing Leftovers

Keep leftover cake covered tightly with plastic wrap or stored in an airtight container at room temperature for up to two days, or in the fridge for up to four days to maintain freshness and moistness.

Freezing

This cake freezes beautifully. Wrap individual layers or the whole cake tightly in plastic wrap, then aluminum foil. Freeze for up to three months. To thaw, leave it in the fridge overnight before serving.

Reheating

Instead of reheating, this cake is best enjoyed cold or at room temperature to preserve the texture of the frosting and the candy pieces. If needed, let it sit at room temperature for 30 minutes before serving for the best experience.

FAQs

Can I substitute regular M&M’S for Peanut Butter M&M’S?

Absolutely! While Peanut Butter M&M’S provide a distinct peanut flavor, regular M&M’S add colorful crunch and sweetness. Mixing both creates a fun twist.

What type of peanut butter should I use for the frosting?

Creamy peanut butter works best for a smooth, spreadable frosting. Natural or chunky peanut butter can be used but will change the texture slightly.

Do I have to drain the yogurt before mixing it in?

Yes, draining the yogurt removes excess moisture which keeps the batter from becoming too runny and ensures a perfect cake consistency.

Can I make this cake gluten-free?

You can substitute all-purpose flour with a gluten-free baking blend, but make sure it contains xanthan gum for proper texture and rise.

How long can I keep the frosted cake at room temperature?

Due to the peanut butter frosting, it’s best to keep the cake refrigerated and only bring it to room temperature just before serving.
