Storing and Reheating Peanut Butter Brownies

  • Place cooled brownies in an airtight container with wax paper between layers. Keep refrigerated for up to 5 days, maintaining their delicious texture and flavor.
  • Wrap individual brownies tightly in plastic wrap, then place in a freezer-safe bag. Freeze for maximum 3 months to preserve their rich taste and soft consistency.
  • Store in a sealed container at room temperature for 2-3 days, keeping away from direct sunlight and heat sources to prevent texture changes.
  • Warm refrigerated brownies in microwave for 10-15 seconds on medium power. For frozen brownies, thaw overnight in refrigerator before gently reheating to maintain their gooey chocolate ganache and soft peanut butter layers.

Good Matches for PB Brownies

Pair Peanut Butter Chocolate Delight with Complementary Beverages:
  • Robust Red Wine Companion: Select a bold, full-bodied red wine like Cabernet Sauvignon or Merlot to balance the rich, sweet chocolate and nutty peanut butter flavors. The wine's tannins will cut through the dessert's richness, creating a sophisticated tasting experience.
  • Creamy Milk Indulgence: Enjoy a cold glass of whole milk or a classic chocolate milk to enhance the brownie's decadent chocolate and peanut butter notes. The cool, smooth dairy complements the warm, dense texture of the brownies.
  • Espresso Flavor Enhancer: Brew a strong shot of espresso or serve a classic cappuccino alongside the brownies. The intense coffee's bitterness will beautifully contrast the sweet, rich dessert, awakening your palate with each bite.
  • Craft Beer Pairing: Choose a chocolate stout or porter with nutty undertones. These dark beers mirror the brownie's chocolate profile while adding a complex, malty depth that harmonizes with the peanut butter's richness.

Peanut Butter Brownie Variations

  • Gluten-Free Peanut Butter Brownies: Replace box brownie mix with gluten-free brownie mix, ensuring all ingredients are certified gluten-free. Use almond flour or gluten-free flour blend for added texture.
  • Vegan Chocolate Peanut Butter Squares: Substitute regular butter with coconut oil, use dairy-free chocolate chips, and replace eggs with flax eggs. Swap powdered sugar with maple syrup or coconut sugar for a plant-based version.
  • Low-Sugar Brownie Option: Use sugar-free brownie mix or reduce sugar content by half. Swap powdered sugar with monk fruit sweetener or stevia. Choose natural peanut butter without added sugars to maintain lower sugar profile.
  • Nutty Alternative Brownies: Replace peanut butter with almond butter or cashew butter for different flavor profiles. Consider adding chopped nuts like walnuts or pecans into brownie batter for extra crunch and nutrition.

FAQs

  • Can I use homemade brownie mix instead of boxed mix?

Yes, absolutely! A homemade brownie batter works perfectly. Just ensure the consistency is similar to the boxed mix for best results.

  • How do I know if my peanut butter mixture is the right consistency?

The mixture should be smooth and spreadable. If it’s too thick, add a small amount of milk to thin it out. It should easily drop from a spoon.

  • What type of peanut butter works best for this recipe?

Creamy, smooth peanut butter is ideal. Avoid natural peanut butters that separate, as they can make the mixture too runny or grainy.

  • Can I skip the chocolate ganache topping?

While the ganache adds richness, you can omit it if you prefer. The brownies will still be delicious with just the peanut butter and brownie layers.

Steps to Make Peanut Butter Brownies

Steps to Make Peanut Butter Brownies

Step 1: Prepare the Baking Space

Warm up your oven to 350°F.

Line a 9×9 inch baking pan with parchment paper and give it a light grease coating.

This trick ensures easy removal and prevents sticking.

Step 2: Create the Brownie Base

Mix the brownie batter according to package instructions.

Pour about two-thirds of the batter into the prepared pan.

Use a spatula to spread the mixture evenly, creating a smooth foundation for your delicious treat.

Step 3: Whip Up the Peanut Butter Filling

In a mixing bowl, combine:
  • Softened butter
  • Creamy peanut butter
  • Powdered sugar

Beat the ingredients until they become smooth and creamy.

If the mixture feels too thick, add a splash of milk to achieve the right consistency.

Drop spoonfuls of the peanut butter mixture over the brownie base, allowing for a rustic, swirled appearance.

Step 4: Layer and Marble the Brownies

Drizzle the remaining brownie batter over the peanut butter layer.

Gently swirl with a spatula to create a beautiful marbled effect.

Don’t worry about perfect coverage – the uneven pattern adds character to your brownies.

Step 5: Bake to Perfection

Slide the pan into the preheated oven.

Bake for approximately 30 minutes.

Check doneness by inserting a toothpick into the center – it should come out clean.

Allow the brownies to cool completely in the pan.

Step 6: Craft the Chocolate Ganache

Heat heavy cream in the microwave until very hot but not boiling.

Pour the cream over chopped chocolate in a bowl.

Cover and let sit for a few minutes, then stir until the mixture becomes smooth and glossy.

Step 7: Finish and Chill

Pour the ganache over the cooled brownies, using a spatula to spread it evenly.

Refrigerate for about an hour to set the ganache.

Once firm, lift the brownies out using the parchment paper, slice into squares, and indulge in your delectable creation.

Ingredients

Scale

Main Ingredients:

  • 1 box brownie mix
  • 3/4 cup creamy peanut butter
  • 1/2 cup powdered sugar

Fat and Dairy Ingredients:

  • 3 tablespoons softened butter
  • 3 tablespoons heavy cream

Chocolate Ingredients:

  • 4 ounces chopped chocolate (bittersweet or semi-sweet)

Note: Include additional ingredients specified on the brownie mix box for preparation.


Instructions

  1. Preheat oven to 350°F. Line a 9×9″ pan with parchment paper and apply light grease. Prepare brownie mix according to package instructions, then transfer approximately two-thirds of the batter into the prepared pan, spreading evenly with a spatula.
  1. Create peanut butter filling by combining softened butter, peanut butter, and powdered sugar until smooth. If mixture feels dense, incorporate a small amount of milk to achieve spreadable consistency. Gently place peanut butter mixture dollops across the initial brownie layer.
  1. Drizzle remaining brownie batter over the peanut butter layer, carefully smoothing with a spatula. Allow some peanut butter to peek through, creating an attractive marbled visual effect.
  1. Transfer pan to preheated oven and bake for approximately 30 minutes. Test doneness by inserting a toothpick into the center—it should emerge clean. Allow brownies to cool completely within the pan to maintain structural integrity.
