Step-by-Step Guide: Crafting Your Reese’s Pieces Brownies

Baking these incredible Reese’s Pieces Brownies is a straightforward process that yields truly spectacular results. Follow these simple steps to create a dessert that will impress everyone!

  • Step 1: Prepare Your Baking Environment. Begin by preheating your oven to 350 degrees Fahrenheit (175°C). This ensures your oven is at the correct temperature for even baking. Next, take a 9×13 inch baking pan and generously spray it with a non-stick cooking spray. You can also line it with parchment paper for easier removal and cleaner slices.

Step 2: Melt the Chocolate Base. Grab a large microwave-safe bowl. Add the butter and chocolate chips. Heat them in the microwave in 30-second intervals, stirring well after each interval, until the mixture is completely melted and smooth. Be careful not to overheat. Once melted, set aside to cool slightly while you prepare other ingredients.

Step 3: Combine Wet Ingredients. To the slightly cooled chocolate and butter mixture, stir in the granulated sugar, brown sugar, and vanilla extract until well combined. Next, add the eggs, one at a time, mixing thoroughly after each addition until fully incorporated. This step creates a glossy, cohesive base for your brownies.

Step 4: Incorporate Dry Ingredients. Gradually, using a spatula or spoon, stir in the cocoa powder, all-purpose flour, salt, and baking powder. Mix these ingredients by hand until *just* combined. The key here is to avoid overmixing, as this can lead to tough or cakey brownies. A few streaks of flour are acceptable.

Step 5: Bake to Perfection. Pour the brownie batter evenly into your prepared 9×13 inch baking dish. Spread it gently with a spatula to ensure an even layer. Bake for 20 to 25 minutes. To check for doneness, insert a toothpick into the center; if it comes out with moist crumbs (not wet batter), your brownies are ready. Allow the brownies to cool completely in the pan on a wire rack before proceeding to the frosting stage.

Step 6: Prepare the Peanut Butter Frosting Base. While your brownies are cooling (patience is key!), begin making the decadent peanut butter frosting. In a medium mixing bowl, cream together the softened unsalted butter and creamy peanut butter using an electric mixer until the mixture is light, smooth, and fluffy. Scrape down the sides of the bowl as needed.

Step 7: Achieve Perfect Frosting Consistency. Gradually add the powdered sugar to the peanut butter mixture, alternating with small splashes of milk. Begin with about 1 tablespoon of milk and add more if needed, beating with the mixer after each addition until you reach your desired smooth, spreadable consistency. The frosting should be thick enough to hold its shape but easy to spread.

Step 8: Frost the Brownies. Once the brownies are completely cool to the touch, use an offset spatula or the back of a spoon to evenly spread the luscious peanut butter frosting over the entire surface. A thick, even layer is what you’re aiming for.

Step 9: Add the Drizzle and Topping. For the chocolate drizzle, melt the semi-sweet chocolate chips and butter together in a microwave-safe bowl, heating in 30-second intervals and stirring until smooth. Pour the melted chocolate into a piping bag or a small ziplock bag with a tiny corner snipped off. Drizzle the chocolate artfully over the peanut butter frosting. Finally, generously sprinkle the chopped Reese’s Peanut Butter Cups and Reese’s Pieces over the top. Allow the topping to set for about 15-20 minutes at room temperature, or briefly in the refrigerator, before slicing and serving. Enjoy your magnificent creation!

Frequently Asked Questions About Baking Brownies

Here are some common questions we receive about making and storing these delicious Reese’s Pieces Brownies. Knowing these tips will help you achieve perfect results every time.

How should I store leftover Reese’s Pieces Brownies?

To maintain their freshness and delicious texture, refrigerate any leftover brownies in an airtight container. They will stay wonderfully moist and flavorful for up to 4-5 days. Bringing them to room temperature for a few minutes before serving can enhance their texture.

Can I freeze these brownies?

Absolutely! These brownies freeze beautifully. To freeze, ensure they are completely cooled, then wrap individual slices or the entire pan (if unfrosted) tightly in plastic wrap, followed by a layer of aluminum foil. Store them in the freezer for up to 2 months. Thaw them in the refrigerator overnight or at room temperature for a few hours before serving. If frozen with frosting, the frosting texture may change slightly upon thawing but will still be delicious.

What kind of chocolate chips should I use for the brownies?

For the fudgiest and most flavorful brownies, we recommend using good quality semi-sweet chocolate chips or chopped baking chocolate. You can also experiment with dark chocolate chips for a richer, less sweet brownie, or milk chocolate chips for a sweeter, creamier taste. The quality of your chocolate significantly impacts the final taste.

Expert Tips for Brownie Perfection

Achieving the perfect Reese’s Pieces Brownies is easy with a few insider tricks. These pro tips will ensure your brownies are consistently fudgy, flavorful, and beautifully presented.

  • Allow brownies to cool completely before frosting. This is perhaps the most crucial tip! Spreading frosting on warm brownies will cause it to melt and create a messy, unappetizing result. Patience is a virtue here; let them cool down fully, ideally for several hours or even in the refrigerator for a quick chill, before adding the peanut butter frosting.
  • Do not overmix the brownie batter. Overmixing the flour once it’s added can develop the gluten too much, leading to tough, cakey brownies rather than the desirable fudgy texture. Mix until the ingredients are *just* combined, with a few streaks of flour still visible.
  • Allow to cool before cutting. Just like frosting, cutting warm brownies can be challenging. They will be soft and prone to crumbling, and the edges won’t be clean. For neat, perfectly shaped slices, allow the brownies to cool and set completely. Using a warm, sharp knife (run under hot water and wipe dry between cuts) can also help achieve clean lines.
  • Natural peanut butter is not recommended. While we love natural peanut butter for many uses, it often separates and has a different oil content and texture compared to conventional creamy or chunky peanut butter. For the best frosting consistency and flavor in this recipe, stick to a standard creamy (or chunky, if you prefer) peanut butter, such as Jif or Skippy.
  • Use room temperature ingredients for the frosting. Ensure your unsalted butter is properly softened (but not melted) for the frosting. This allows it to cream smoothly with the peanut butter and powdered sugar, resulting in a light and airy frosting without lumps.
  • Line your baking pan for easy removal. For effortless cleanup and easy brownie removal, line your 9×13 inch baking pan with parchment paper, leaving an overhang on the sides. Once the brownies are cooled, you can simply lift them out of the pan.
  • Quality cocoa makes a difference. Invest in a good quality unsweetened cocoa powder for a deep, rich chocolate flavor in your brownies. Dutch-processed cocoa powder can give a darker color and mellower chocolate taste.
