How to Make Milk Chocolate Peanut Butter Brownies Recipe

Step 1: Preheat your oven

Set your oven to 325 degrees Fahrenheit and let it come to temperature. This moderate heat level ensures the brownies bake evenly and develop that perfect fudgy texture without becoming dry or crumbly.

Step 2: Prepare your baking pan

Grab an 8×8 or 9×9 baking pan and spray it generously with cooking spray. Then line it with parchment paper, letting the paper hang over two sides for easy lifting once the brownies are baked. This little step is a game-changer for neat, clean squares and effortless removal.

Step 3: Melt chocolate and butter

In a microwave-safe container, combine the bittersweet chocolate chips and butter. Heat on high for 30 seconds, stir well, then continue heating in short bursts until everything is smooth and fully melted. Let it rest for a few minutes and stir again to perfect the silky chocolate mixture.

Step 4: Mix eggs and sugar

Using a fork, beat together the eggs and sugar in a medium bowl until well combined. This step is crucial to incorporate air, which lightens the dense chocolate batter slightly without losing that signature fudginess.

Step 5: Add salt, vanilla, and melted chocolate

Next, stir in the salt and vanilla extract, then pour in your beautifully melted chocolate and butter mixture. Combining these now helps to build the rich, chocolate-forward foundation that will shine throughout the brownie.

Step 6: Incorporate the flour

Add the flour gradually and stir just until you no longer see dry flour. Over-mixing here can make brownies tough, so gentle folding keeps them tender and dense in all the right ways.

Step 7: Fold in the mix-ins

Sprinkle in the peanut butter chocolate chips, miniature marshmallows, and semi-sweet chocolate chips. These mix-ins create irresistible pockets of sweetness and varied textures that make every bite exciting and delightful.

Step 8: Add the peanut butter swirl

Pour half the brownie batter into the prepared pan and smooth it out. Warm the creamy peanut butter slightly, then dollop it over the layer. Use a knife or skewer to swirl it through the batter gently. Top with the remaining batter and smooth again for an even finish.

Step 9: Bake to perfection

Slide your pan into the oven and bake for 25 to 30 minutes. You’re looking for the center to set while maintaining a fudgy interior. A toothpick inserted will have just a few moist crumbs but should not be wet with batter.

Step 10: Cool completely

Once out of the oven, transfer the pan to a wire rack. Let the brownies cool fully before lifting them out of the pan using the parchment overhang. Cutting while warm leads to messy, uneven squares, but patience here rewards you with clean, perfectly shaped brownies.

How to Serve Milk Chocolate Peanut Butter Brownies Recipe

Garnishes

Add a sprinkle of crushed peanuts or a drizzle of melted chocolate on top for an eye-catching presentation and added crunch. A light dusting of powdered sugar can also add a pretty, classic finish without overpowering the flavors.

Side Dishes

These brownies are divine on their own but pairing with a scoop of vanilla ice cream, fresh berries, or a dollop of whipped cream can elevate your dessert experience. A hot mug of coffee or cold glass of milk also complements the rich milk chocolate and peanut butter flavors perfectly.

Creative Ways to Present

For parties or special occasions, cut the brownies into bite-size squares and arrange on a platter with colorful toothpicks or decorate each with a mini peanut butter cup. You can also sandwich them with marshmallow fluff or spread a layer of peanut butter frosting for a decadent twist.

Make Ahead and Storage

Storing Leftovers

Keep leftover Milk Chocolate Peanut Butter Brownies Recipe in an airtight container at room temperature for up to three days. This helps maintain their fudgy texture and keeps the flavors fresh and inviting every time you grab a piece.

Freezing

For longer storage, freeze the brownies covered tightly in plastic wrap and aluminum foil for up to three months. Thaw them overnight in the refrigerator or at room temperature before enjoying their rich, melty goodness.

Reheating

If you prefer warm brownies, briefly microwave a piece for 15 to 20 seconds or pop it in a low oven for a few minutes. This softly melts the chocolate chips and peanut butter, bringing back that freshly baked feel and gooey delight.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter will add an extra layer of texture to your brownies, giving you delightful little bites of peanut crunch that contrast beautifully with the smooth chocolate.

What type of chocolate chips works best?

The recipe calls for bittersweet, semi-sweet, and milk chocolate chips because the variety creates a balanced flavor profile. However, you can adjust according to your preference—dark chocolate for richness, or milk chocolate for sweetness.

How do I know when the brownies are done?

Look for edges that are set and a center that appears mostly firm but still has a slight wobble. A toothpick inserted should come out with moist crumbs but not raw batter. This ensures the fudgy texture you want.

Can I substitute the mini marshmallows?

If you’re not a fan of marshmallows, you can omit them or replace with chopped nuts or extra chocolate chips. The brownies will still be deliciously rich and gooey without them.

Is it necessary to let the brownies cool before cutting?

Yes! Cooling completely helps the brownies set so they cut cleanly. Warm brownies tend to be too soft and may crumble or stick to your knife, making a mess.
