Introduction
These chewy REESE’S PIECES peanut butter brownies are a delightful twist on a classic treat, combining rich peanut butter flavor with colorful candy pieces. Perfectly chewy and packed with sweetness, they’re sure to satisfy any chocolate and peanut butter lover’s cravings.

Ingredients
- ⅔ cup butter (melted)
- 1⅓ cups granulated sugar
- 1 cup light brown sugar
- 4 large eggs
- 2 teaspoons vanilla extract
- 1 cup creamy or chunky peanut butter
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- ¼ teaspoon salt
- ½ cup Reese’s Pieces
Instructions
- Step 1: Preheat your oven to 350°F (175°C). For easier removal and cleanup, line an 11 x 13-inch metal or glass baking pan with parchment paper.
- Step 2: In a large bowl, mix together the melted butter, granulated sugar, light brown sugar, and peanut butter until well combined.
- Step 3: Slowly add the eggs, vanilla extract, and a pinch of salt to the wet mixture, stirring thoroughly after each addition.
- Step 4: In a separate bowl, whisk together the all-purpose flour and baking powder to evenly distribute the leavening agent.
- Step 5: Gradually add the dry ingredients to the wet ingredients, mixing gently or folding just until combined. Avoid over mixing to keep the brownies chewy instead of cakey.
- Step 6: Spread the batter evenly into the prepared pan. Sprinkle the Reese’s Pieces evenly over the top of the batter.
- Step 7: Bake for 30 to 35 minutes, until the top is firm but the center remains moist.
- Step 8: Let the brownies cool in the pan for at least 30 minutes before lifting out with the parchment paper and cutting into squares.
Tips & Variations
- Try using chunky peanut butter for added texture or creamy for a smoother bite.
- For extra chocolate flavor, sprinkle mini chocolate chips on top before baking.
- Allow brownies to cool completely for cleaner cutting and better texture.
- If you don’t have Reese’s Pieces, substitute with M&M’s or chopped peanuts for a different twist.
Storage
Store brownies in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. Reheat briefly in the microwave to enjoy warm and gooey. These brownies also freeze well for up to 2 months—thaw overnight at room temperature before serving.

FAQs
Can I use crunchy peanut butter instead of creamy?
Yes, crunchy peanut butter adds a nice texture contrast to the chewy brownies, but creamy works just as well if you prefer a smoother consistency.
How do I know when the brownies are done?
They are ready when the top feels firm to the touch, but the center still feels slightly moist. Avoid overbaking to keep them chewy and soft inside.

Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking the brownies.
