Irresistible Reese’s Stuffed Brownie and Peanut Butter Frosting Treat

How to Make Reese’s Stuffed Brownie and Peanut Butter Frosting

Step 1: Prepare the Brownie Batter

Start by mixing your brownie ingredients according to the recipe or box instructions, combining eggs, melted butter, sugar, and cocoa powder (or brownie mix) until smooth and glossy.

Step 2: Layer the Batter and Reese’s Cups

Pour half of the brownie batter into a greased baking pan, then arrange the Reese’s Peanut Butter Cups evenly over the surface. Cover with the remaining batter, gently spreading to seal the cups inside for the ultimate surprise center.

Step 3: Bake to Perfection

Bake in a preheated oven at 350°F (175°C) for about 25-30 minutes, or until a toothpick inserted near the edge comes out with just a few moist crumbs—this keeps the brownies fudgy and gooey.

Step 4: Prepare the Peanut Butter Frosting

While the brownies cool, whisk together peanut butter, powdered sugar, vanilla extract, and a splash of cream or milk to reach your desired spreading consistency.

Step 5: Frost and Finish

Spread the rich peanut butter frosting generously over the slightly cooled brownies, then let everything set for about 20 minutes before slicing and serving.

Pro Tips for Making Reese’s Stuffed Brownie and Peanut Butter Frosting

Use Room Temperature Ingredients: Ensures smooth batter and frosting without lumps or graininess.
Avoid Overbaking: Pull the brownies from the oven when they still look slightly underdone for that perfect molten center.
Choose Natural Peanut Butter: For a more authentic and less greasy frosting, opt for natural or homemade peanut butter.
Chill Before Cutting: Refrigerate brownies for at least 30 minutes after frosting to achieve neater slices.
Add a Sprinkle of Sea Salt: Enhances the chocolate and peanut butter flavors by balancing sweetness.

How to Serve Reese’s Stuffed Brownie and Peanut Butter Frosting

Garnishes

Top with crushed Reese’s cups, roasted peanut pieces, or a dusting of cocoa powder for eye-catching presentation and extra texture.

Side Dishes

Pair with a scoop of vanilla or salted caramel ice cream, fresh berries, or a drizzle of chocolate sauce to complement and elevate the dessert experience.

Creative Ways to Present

Serve in individual mason jars layered with whipped cream or peanut butter mousse, or cut into bite-sized truffles and dipped in melted chocolate for a party-friendly option.

Make Ahead and Storage

Storing Leftovers

Store leftover brownies tightly covered at room temperature for up to 3 days or refrigerated for up to a week, ensuring the frosting stays fresh and creamy.

Freezing

Wrap cooled brownies individually in plastic wrap and then in foil before freezing; they’ll keep for up to 3 months and thaw quickly at room temperature.

Reheating

Warm leftover brownies gently in the microwave for 10-15 seconds to revive that soft, gooey texture without melting the frosting entirely.

FAQs

Can I use homemade brownies instead of a mix?

Absolutely! Homemade brownies work wonderfully and allow you to control ingredients for a richer or healthier twist.

What if I don’t have Reese’s Peanut Butter Cups on hand?

You can substitute with any peanut butter candy or even dollops of peanut butter to create a similar center.

How do I make the frosting thicker?

Add more powdered sugar a tablespoon at a time until you reach your desired thickness, or chill it briefly to firm up.

Can I make this recipe gluten-free?

Yes, use a gluten-free brownie mix or gluten-free cocoa powder blend and confirm that all other ingredients are gluten-free.

Is it possible to make this recipe dairy-free?

Switch to plant-based butter, a dairy-free milk alternative, and vegan peanut butter to make a dairy-free Reese’s Stuffed Brownie and Peanut Butter Frosting.
