Step-by-Step Guide to Peanut Butter Stuffed Brownies Bliss

  1. Preparation: Begin by preheating your oven to 350 degrees and prepare an 8-inch baking dish with non-stick spray, or line it with foil or parchment paper for easy removal.
  2. Mix the Brownie Batter: In a bowl, combine the oil and melted chocolate. Stir in the eggs and sugar until the mixture is well blended. Gradually add the flour, baking powder, and salt, mixing until everything is combined without overmixing.
  3. Layer the Brownies: Pour half of the brownie batter into the prepared pan. Arrange the peanut butter cups evenly over the batter, pressing them down slightly. Then, pour the remaining batter over the top, spreading it to cover the peanut butter cups completely.
  4. Bake to Perfection: Bake the brownies for 20-25 minutes, or until a tester comes out mostly clean. The key to fudgy brownies is to avoid overbaking.
  5. Add the Topping: As soon as the brownies are out of the oven, sprinkle the chocolate chips over the top. Cover the pan with foil and let it sit for about 10 minutes. The residual heat will melt the chocolate chips. Remove the foil and spread the melted chocolate evenly over the brownies. Finally, sprinkle the chopped peanut butter cups over the melted chocolate layer.
  6. Cool and Serve: Allow the brownies to cool completely before slicing. This patience will be rewarded with clean cuts and perfectly layered brownies that are as beautiful as they are delicious.

Serving and Storage Tips for Peanut Butter Stuffed Brownies

Once you’ve baked these heavenly Peanut Butter Stuffed Brownies, knowing how to serve and store them will ensure they remain just as delicious after the first bite. Here are some expert tips to help you enjoy these treats to the fullest:

Serving Tips:

  • Let Them Cool: Patience is key! Allow the brownies to cool completely in the pan on a wire rack before attempting to cut them. This cooling period helps the brownies set, making them easier to slice.
  • Cutting: For clean and neat slices, use a sharp knife. Running the knife under hot water and wiping it dry between cuts can make slicing smoother and prevent the brownie from sticking to the knife.
  • Serving Temperature: These brownies are versatile. Enjoy them at room temperature for a firmer texture or slightly warmed for a gooey, decadent experience. A few seconds in the microwave can make the peanut butter and chocolate melt slightly, enhancing the flavors.
  • Add a Topping: While these brownies are a treat on their own, serving them with a scoop of vanilla ice cream or a dollop of whipped cream can turn them into an extra special dessert.

Storage Tips:

  • Room Temperature: Store the cooled brownies in an airtight container at room temperature. They will keep for up to 3 days, retaining their moisture and flavor.
  • Refrigerate for Longevity: For longer storage, you can refrigerate the brownies. Place them in an airtight container, separating layers with parchment paper to prevent them from sticking together. When stored in the refrigerator, they can last up to a week. Allow them to come to room temperature before serving or warm them slightly in the microwave.
  • Freezing: These brownies freeze well. Wrap individual brownie squares tightly in plastic wrap and then place them in a ziplock freezer bag or an airtight container. They can be frozen for up to 3 months. Thaw overnight in the refrigerator or at room temperature for a few hours before enjoying.

Freshness Tip:

  • Revive Your Brownies: If the brownies begin to dry out, you can revive them by microwaving a brownie for a few seconds with a damp paper towel placed over it. This will add moisture back into the brownie, making it soft and fudgy again.

By following these serving and storage tips, you can ensure that every bite of your Peanut Butter Stuffed Brownies is as perfect as the first. Whether you’re enjoying them freshly baked or savoring them days later, these tips will help maintain their delicious texture and flavor, making them a hit at any time.


1. Can I use natural peanut butter in the peanut butter cups?

Yes, you can use peanut butter cups made with natural peanut butter for this recipe. However, keep in mind that natural peanut butter tends to be oilier and may slightly alter the texture of the filling. For the best results, use peanut butter cups that hold their shape well during baking.

2. How can I make these brownies if I don’t have unsweetened chocolate?

If you don’t have unsweetened chocolate, you can substitute it with 3 tablespoons of unsweetened cocoa powder plus 1 tablespoon of butter, oil, or shortening for every ounce of unsweetened chocolate required. This mixture won’t exactly replicate the texture and taste of melted unsweetened chocolate but will provide a satisfactory alternative for making the brownies.

3. Are these brownies gluten-free?

As written, this recipe is not gluten-free because it calls for regular all-purpose flour. To make gluten-free peanut butter stuffed brownies, substitute the all-purpose flour with a gluten-free flour blend designed for baking. Make sure to check that all other ingredients, including the peanut butter cups, are certified gluten-free.

4. How do I prevent the peanut butter cups from sinking to the bottom of the pan?

To prevent the peanut butter cups from sinking to the bottom of the pan, you can lightly coat them in flour before pressing them into the batter. This helps to create a barrier that reduces sinking. However, in this recipe, the peanut butter cups are layered between two layers of brownie batter, which also helps to keep them distributed throughout the brownies rather than sinking to the bottom.


These Peanut Butter Stuffed Brownies are more than just a dessert; they’re an experience. With their gooey, fudgy texture, rich chocolate flavor, and the creamy surprise of peanut butter cups hidden inside, they’re sure to become a favorite. Whether for a special occasion, a treat for the family, or simply to satisfy a craving, these brownies are the ultimate indulgence for peanut butter and chocolate lovers alike. So, preheat your oven and get ready to bake your way to bliss!
