Reese's Stuffed Brownies Recipe - Recipe Image

Ingredients

1 Pillsbury family size brownie mix (19.5 ounces)
1 large egg
4 ounces cream cheese, softened
1/4 cup salted butter, softened
16 full-size Reese’s peanut butter cups, frozen
1/2 cup salted butter, softened
1 cup creamy peanut butter
3 tablespoons 2% milk
2 cups powdered sugar
2 ounces semi-sweet chocolate

Instructions

Step 1: Preheat the oven to 350ºF. Line an 8×8″ baking pan with parchment paper or spray it with cooking spray.
Step 2: In a large bowl, combine the brownie mix, egg, softened cream cheese, and 1/4 cup softened butter using a stand mixer or electric mixer. Mix until well combined and thick, scraping down the sides as needed. Spread the batter evenly in the prepared pan.
Step 3: Press the frozen Reese’s peanut butter cups into the batter in a 4×4 grid, ensuring they sit flush with the surface. Bake for about 28 minutes.
Step 4: While the brownies bake, prepare the peanut butter frosting. In a mixer, blend 1/2 cup softened butter, creamy peanut butter, powdered sugar, and milk for 2–3 minutes until light and fluffy.
Step 5: Let the brownies cool completely, then spread the peanut butter frosting evenly over the top.
Step 6: Place the semi-sweet chocolate in a microwave-safe bowl and heat in 15-second intervals, stirring between each, until fully melted. Drizzle the melted chocolate over the frosting and let the brownies set before cutting and serving.

Tips & Variations

Freeze the Reese’s cups before baking to help them retain their shape and prevent melting into the batter.
For a richer frosting, substitute half of the 2% milk with heavy cream.
Use dark chocolate instead of semi-sweet for a deeper chocolate flavor in the drizzle.
Add a pinch of sea salt on top of the chocolate drizzle to enhance the peanut butter flavor.

Storage

Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. Bring to room temperature before serving for the best flavor and texture. You can also freeze brownies, wrapped tightly, for up to 2 months; thaw overnight in the refrigerator and then let warm slightly before enjoying.

Serve this delicious recipe with your favorite sides.

FAQs

Can I use a different brownie mix for this recipe?

Yes, you can use any boxed brownie mix of your choice. Just be sure to follow the package instructions for the batter and add the cream cheese and butter as directed for a fudgy texture.

Do the Reese’s cups melt inside the brownies?

Since the peanut butter cups are frozen before baking and pressed only slightly into the batter, they soften but mostly keep their shape, creating a delicious layered surprise.

Ingredients

Scale

Brownie Batter

1 Pillsbury family size brownie mix (19.5 ounces)
1 large egg
4 ounces cream cheese, softened
1/4 cup salted butter, softened

Add-ins

16 full-size Reese’s peanut butter cups, frozen

Peanut Butter Frosting

1/2 cup salted butter, softened
1 cup creamy peanut butter
2 cups powdered sugar
3 tablespoons 2% milk

Chocolate Drizzle

2 ounces semi-sweet chocolate

Instructions

Preheat and prepare pan: Preheat your oven to 350ºF. Line an 8×8-inch baking pan with parchment paper or generously spray with cooking spray to prevent sticking.
Make brownie batter: In a stand mixer or with an electric mixer, combine the brownie mix, egg, softened cream cheese, and 1/4 cup softened salted butter. Mix well until fully combined and the batter is thick. Use a rubber spatula to scrape down the sides of the bowl as needed. Spread this dense batter evenly in the prepared baking pan.
Insert peanut butter cups: Press the frozen Reese’s peanut butter cups into the batter in a 4×4 grid pattern, arranging 16 cups total. Push each one gently enough so the top of the peanut butter cups sits flush with the batter surface. This layering ensures gooey chocolate and peanut butter centers.
Bake the brownies: Place the pan in the preheated oven and bake for about 28 minutes. The brownies should be set and a toothpick inserted near a peanut butter cup comes out mostly clean with a few moist crumbs. Remove from oven and allow to cool completely.
Prepare peanut butter frosting: While the brownies bake, blend 1/2 cup softened salted butter, 1 cup creamy peanut butter, 2 cups powdered sugar, and 3 tablespoons 2% milk in a stand mixer. Beat for 2-3 minutes until the frosting is light, fluffy, and spreadable.
Frost the brownies: Once brownies are fully cooled, generously spread the peanut butter frosting evenly over the top layer.
Melt chocolate for drizzle: Place 2 ounces of semi-sweet chocolate in a microwave-safe bowl and heat in 15-second intervals, stirring well between each to prevent burning. Continue until chocolate is fully melted and smooth.
Drizzle and set: Drizzle the melted chocolate decoratively over the frosted brownies. Allow the chocolate to set at room temperature before slicing and serving.

Notes

Use frozen peanut butter cups to help them retain their shape while baking.
Ensure the brownies are completely cool before frosting to avoid melting the frosting.
If desired, substitute 2% milk in frosting with almond milk for a dairy alternative.
Chocolate drizzle can be replaced with chocolate chips melted with a small amount of butter for extra shine.
Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
