4 large eggs: Binds the mixture together while enhancing fluffiness.
2 teaspoons vanilla extract: Elevates overall flavor, rounding out the ingredients.
1 cup creamy or chunky peanut butter: The star ingredient that provides its distinct flavor and texture. Choose chunky for added crunch!
2 cups all-purpose flour: Forms the structure of your brownies.
2 teaspoons baking powder: Ensures they rise just enough without turning cake-like.
¼ teaspoon salt: Balances sweetness, enhancing each bite.
½ cup REESE’S PIECES: Add pops of delightful crunchiness and playful color.

How to Make Chewy REESE’S PIECES Peanut Butter Brownies

Preheat your oven to 350°F (175°C) to ensure the perfect bake.
Line an 11 x 13 metal or glass baking pan with parchment paper, which will allow for easy removal of your delicious brownies once they’ve cooled.
In a large mixing bowl, whisk together the melted butter, creamy peanut butter, granulated sugar, and brown sugar until well combined.
Slowly incorporate the eggs one at a time, followed by the vanilla extract and a pinch of salt, ensuring every ingredient is thoroughly blended.
In a separate bowl, whisk together the all-purpose flour and baking powder. This helps to evenly distribute the leavening agent throughout the mix.
Gently fold the dry ingredients into the peanut butter mixture. Remember, do not over mix; you want to keep those chewy, fudgy brownies from turning into cake.
Smooth the batter into the prepared baking pan. Then, sprinkle the REESE’S PIECES evenly across the surface, creating pockets of color and crunch within the decadent brownie mix.
Bake in the preheated oven for 30-35 minutes. Your brownies should feel firm on top while remaining slightly moist in the center, offering that delightful gooey texture.
Finally, let the brownies cool in the pan for at least 30 minutes before cutting them into squares, allowing their flavors to meld and set properly.

Chef’s Notes & Helpful Tips

Make-ahead tips: You can prepare the batter ahead of time and store it in the refrigerator for up to 24 hours before baking. Just store it in an airtight container and allow it to sit for a few minutes before pouring into the baking pan and baking.
Cooking alternatives: Try using an air fryer at 320°F for 20-25 minutes for a quicker option; just keep a close watch to ensure they don’t overcook.
Customization ideas: Consider mixing in chocolate chips or butterscotch chips for extra richness. Alternatively, sprinkle sea salt on top before baking for a sweet and salty contrast.

Common Mistakes to Avoid

Overmixing: Mixing the batter too much can lead to brownies that are more cake-like than chewy. The key to divine chewy brownies lies in minimal mixing after combining the dry and wet ingredients.
Underbaking: While it’s tempting to pull them out of the oven early, slightly underbaked brownies yield that rich, gooey center we all crave, but ensure they are firm on top to avoid a mushy mess.
Skipping the cool-down: Impatience is common; however, skipping the cooling step can lead to brownies that crumble when cut. Allow them to cool for at least 30 minutes—your reward will be squares that hold their shape beautifully.

Coffee: A strong cup of coffee adds a roasted, earthy contrast to the sweetness, enhancing every decadent bite.
Fruit Salad: Fresh fruit provides a refreshing counterbalance to the richness of the brownies, lightening the dessert experience.
Whipped Cream: A dollop adds a fluffy texture that contrasts delightfully with the dense brownie.
Peanut Butter Drizzle: A creamy peanut butter drizzle enhances the peanut flavor, making it a true delight for enthusiasts.

Storage & Reheating Instructions

Fridge: These brownies keep well in an airtight container in the fridge for up to a week. If you prefer chilled treats, enjoy them straight from the fridge.

FAQs

1. Can I make these brownies gluten-free?
Absolutely! Substitute all-purpose flour with a 1:1 gluten-free flour blend, ensuring to match with appropriately gluten-free ingredients.

2. Can I use old peanut butter that has separated?
If your peanut butter has separated, just give it a good stir until it’s well-mixed again. However, if it’s too old or rancid, it’s best to use fresh peanut butter for both taste and safety.

3. What’s the difference between creamy and chunky peanut butter in this recipe?
Creamy peanut butter provides a smooth, rich texture, while chunky gives delightful bits of peanuts throughout the brownies. Both offer delicious results—I recommend trying both!

4. Can I double this recipe for a larger crowd?
Yes, simply double the ingredients and use a larger baking pan or make them in two separate pans. Just be attentive to baking time, as it may vary slightly.

5. How do I know when they’re done baking?
Look for firm tops and a moist center. A toothpick inserted should come out with a few moist crumbs but not wet batter for the perfect fudgy brownies.
