Step-by-Step Instructions
Peanut Butter Cake
- Preheat and Prepare the Pan
- Preheat your oven to 180°C (350°F) for standard ovens or 160°C (320°F) for fan-forced ovens.
- Grease a quarter sheet pan and line it with parchment paper to prevent sticking.
- Cream the Butter and Sugars
- In a large mixing bowl, add the butter, brown sugar, and caster sugar.
- Using an electric mixer on medium speed, beat the mixture until it turns pale and creamy.
- Add the peanut butter and vanilla extract, and mix until smooth and fully combined.
- Incorporate the Eggs
- Add the eggs one at a time, beating on low speed after each addition until fully incorporated.
- Don’t worry if the mixture appears curdled at this stage; it will come together later.
- Add Dry and Wet Ingredients
- Sift the baking powder, salt, and half of the flour into the bowl.
- Pour in all the milk and mix on low speed until just combined.
- Add the remaining flour and mix until the batter is thick and smooth. Avoid overmixing to prevent a dense cake.
- Bake the Cake
- Pour the batter into the prepared pan, spreading it out evenly with a spatula.
- Bake for 35-40 minutes, or until the top is golden brown and a skewer inserted into the center comes out clean.
- Remove from the oven and allow the cake to cool completely in the pan before frosting.
Chocolate Frosting
- Cream the Butter
- In a large mixing bowl, beat the butter with an electric mixer on medium speed for 2-3 minutes until pale and creamy.
- Melt the Chocolate
- Melt the milk chocolate in a microwave-safe bowl, stirring every 20 seconds until smooth. Allow it to cool slightly before using.
- Incorporate Powdered Sugar and Milk
- Add half of the icing sugar and 1 tablespoon of milk to the butter.
- Beat on low speed until the sugar is fully incorporated, then repeat with the remaining sugar and another tablespoon of milk.
- Add Chocolate and Peanut Butter
- Gradually add the melted chocolate and the peanut butter to the frosting mixture.
- Beat until smooth and fully combined. If the frosting is too thick, add an additional tablespoon of milk.
- Frost the Cake
- Generously spread the frosting over the cooled cake using a spatula.
- Ensure an even layer, smoothing the top for a professional finish.
- Decorate with Mini M&M’s
- Scatter the mini M&M’s evenly over the frosted cake, pressing them gently into the frosting to secure them in place.
Preparation Tips for Success
- Room-Temperature Ingredients: Ensure that your butter, eggs, and milk are at room temperature for smoother blending and a lighter cake texture.
- Don’t Overmix: Overmixing the batter can lead to a dense and tough cake. Mix just until the ingredients are combined.
- Use High-Quality Ingredients: Opt for high-quality milk chocolate and processed peanut butter for the best flavor and texture.
- Check for Doneness: Insert a skewer or toothpick into the center of the cake; if it comes out clean, the cake is done.
- Allow the Cake to Cool Completely: Frosting a warm cake can cause the frosting to melt and slide off. Be patient and let the cake cool completely.
Ingredient Notes and Substitutions
- Peanut Butter: For best results, use a processed peanut butter like Skippy or Jif, as natural peanut butter can alter the texture and consistency of the cake.
- Milk: If you don’t have whole milk, you can substitute with buttermilk for a tangier flavor.
- Chocolate: While milk chocolate is recommended, you can use dark chocolate for a richer, more intense frosting.
- M&M’s: Swap mini M&M’s for crushed Reese’s Pieces or chopped nuts for a different texture and flavor.

Common Mistakes and Troubleshooting
Even experienced bakers can encounter challenges with layered cakes. Below are common pitfalls and how to avoid or fix them:
Mistake 1: Overmixing the Batter
Overmixing can lead to a dense and heavy cake. This happens when the flour is overworked, developing too much gluten.
How to Avoid:
Mix the batter just until the ingredients are combined. Stop as soon as you no longer see streaks of flour.
Fix:
If your batter seems overmixed, gently fold in a tablespoon or two of milk to loosen it before baking. However, avoid overhandling it further.
Mistake 2: Dry Cake
A dry cake can result from overbaking or not measuring ingredients correctly.
How to Avoid:
- Check the cake 5 minutes before the end of the baking time. Insert a toothpick into the center; if it comes out clean, the cake is ready.
- Always measure ingredients precisely, particularly flour. Use the “spoon and level” method for measuring dry ingredients.
Fix:
Brush a small amount of simple syrup (equal parts sugar and water, heated until dissolved) over the cake layers to add moisture.
Mistake 3: Frosting Too Thick or Runny
Getting the frosting consistency right can be tricky. If it’s too thick, it’s difficult to spread; if too runny, it slides off the cake.
How to Avoid:
- Add milk to the frosting a little at a time to achieve the desired consistency.
- If your frosting is too runny, add more sifted powdered sugar, one tablespoon at a time, until thickened.
Fix for Thick Frosting:
- Gradually add milk, one teaspoon at a time, until the frosting is smooth and spreadable.
Fix for Runny Frosting:
- Chill the frosting in the refrigerator for 10–15 minutes to firm it up before spreading. If it’s still too soft, beat in more powdered sugar.
Mistake 4: Uneven Baking
Uneven baking can leave parts of your cake overdone or undercooked.
How to Avoid:
- Use an oven thermometer to ensure your oven is heating accurately.
- Place the cake on the center rack of your oven for even heat distribution.
- Rotate the pan halfway through baking to prevent hot spots from overbaking one side.
Mistake 5: Cake Sticking to the Pan
A stuck cake can ruin its appearance and make frosting challenging.
How to Avoid:
- Always line the pan with parchment paper and grease it thoroughly.
- Allow the cake to cool completely before attempting to remove it from the pan.
Fix:
If your cake is stuck, run a butter knife around the edges to loosen it. Place the pan over a pot of hot water for a few minutes to help release the cake.
Mistake 6: Melted Frosting
Applying frosting to a warm cake can cause it to melt and slide off.
How to Avoid:
- Let the cake cool completely—preferably for 1-2 hours—before frosting.
- If you’re in a hurry, place the cake in the refrigerator for 20–30 minutes to speed up cooling.
Fix:
If your frosting starts to melt, refrigerate the cake and frosting for 15–20 minutes to firm it up before continuing.
Mistake 7: Overdecorating with M&M’s
Too many M&M’s can make the frosting difficult to spread and cause pieces of the cake to fall apart when cutting.
How to Avoid:
Scatter M&M’s evenly and lightly press them into the frosting to secure them in place. Avoid layering too many in one spot.
Storing and Reheating
Proper storage ensures your M&M’s Peanut Butter Cake with Peanut Butter Frosting stays fresh and delicious for days. Follow these tips to store, reheat, and enjoy this cake without losing its flavor or texture.
How to Store the Cake

- Keep it in a cool, dry place away from direct sunlight.
- In the Refrigerator:
For longer storage (up to 5 days), refrigerate the cake.- Cover the cake with plastic wrap or store it in a sealed container to prevent it from absorbing other odors in the fridge.

Thawing Instructions:
- Transfer the slices to the refrigerator and let them thaw overnight.
- Alternatively, leave them at room temperature for 1–2 hours before serving.
How to Reheat the Cake
Reheating slices of cake helps restore the warm, comforting flavors of a freshly baked dessert. Here’s how to do it:
- Microwave Method:
- Place a slice of cake on a microwave-safe plate.
- Heat for 10–15 seconds at medium power.
- Avoid overheating to prevent the frosting from melting.
- Oven Method:
- Preheat your oven to 180°C (350°F).
- Wrap the slice in aluminum foil to retain moisture.
- Warm the cake for about 5–10 minutes.
FAQs
Can I use natural peanut butter instead of processed peanut butter?
While natural peanut butter is healthier, it tends to separate and may alter the texture of the cake and frosting. For best results, use processed peanut butter like Skippy or Jif, which offers consistent flavor and texture.
How can I make this cake gluten-free?
To make the cake gluten-free:
- Substitute the all-purpose flour with a 1-to-1 gluten-free baking flour (available at most grocery stores).
- Ensure all other ingredients, like baking powder and M&M’s, are certified gluten-free.
Can I use dark chocolate instead of milk chocolate in the frosting?
Yes, dark chocolate can be used for a richer, less sweet frosting. Keep in mind that dark chocolate may slightly alter the sweetness of the cake. Adjust the powdered sugar in the frosting as needed.
How far in advance can I make this cake?
You can bake the cake 1–2 days in advance and store it at room temperature in an airtight container. Frost the cake the day of serving for the freshest presentation. If needed, the cake can be fully frosted and stored in the refrigerator for up to 2 days before serving.
Why is my cake too dense or dry?
A dense or dry cake can result from overmixing the batter, overbaking, or incorrect ingredient measurements.
- Solution: Ensure you measure ingredients accurately and mix only until just combined. Keep an eye on the baking time, and test the cake with a toothpick to ensure it’s done but not overbaked.
Can I replace the M&M’s with other toppings?
Absolutely! Some great alternatives include:
- Reese’s Pieces for an extra peanut butter boost.
- Chopped nuts like peanuts or almonds for added crunch.
- Sprinkles for a festive touch.
- Crushed Oreos for a fun and unique flavor combination.
What should I do if my frosting is too sweet?
If your frosting is too sweet, balance it by:
- Adding a pinch of salt to enhance the peanut butter flavor.
- Incorporating a teaspoon of lemon juice or cream cheese to add a slight tanginess.
Can I make this cake without an electric mixer?
Yes, you can make the cake without an electric mixer, but it will require more effort. Use a whisk or wooden spoon to cream the butter and sugars until pale and fluffy. Mixing the batter manually may take longer, so be patient.
What’s the best way to decorate the cake for a special occasion?
To elevate the cake for an event, try these decoration ideas:
- Pipe swirls of frosting on top using a star-tip nozzle for a professional look.
- Arrange the M&M’s in patterns, such as hearts or stars.
