How to Make Peanut Butter Brownies Recipe

Step 1: Get Ready

Start by preheating your oven to 350°F (175°C). Prepare an 8×8-inch baking pan by greasing it well or lining it with parchment paper to make sure your brownies come out clean and perfect every time.

Step 2: Mix the Sugars and Butter

In a large bowl, whisk together the melted butter with both the granulated and brown sugars until smooth. This step is key to ensuring your brownies have that lovely shiny crack on top and a moist texture inside.

Step 3: Add the Eggs and Vanilla

Next, crack in the eggs and pour in the vanilla extract. Mix these in until everything is fully combined and the batter looks silky smooth. This lets the eggs incorporate air for that fudgy but slightly springy bite.

Step 4: Combine the Dry Ingredients

Now, sift together the unsweetened cocoa powder, flour, salt, and baking powder. Gently fold the dry ingredients into the wet mixture just until combined. Be careful not to overmix; you want tender brownies, not tough ones!

Step 5: Pour the Batter

Pour the brownie batter into your prepared baking pan and use a spatula to spread it out evenly. A level surface means even baking and perfectly uniform pieces after slicing.

Step 6: Add the Peanut Butter Swirls

Warm the creamy peanut butter slightly to make it easy to drizzle. Spoon it over the brownie batter in dollops, then use a knife or skewer to gently swirl the peanut butter throughout the batter. The result is a beautiful marbled effect packed with flavor in every bite.

Step 7: Bake to Perfection

Bake the brownies for 20 to 25 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs. Keep a close eye to avoid overbaking because you want them fudgy, not dry.

Step 8: Cool and Cut

Allow the brownies to cool completely right in the pan. This helps them set and makes slicing easier. Once cool, cut into 12 generous squares and get ready to enjoy a truly special treat.

How to Serve Peanut Butter Brownies Recipe

Garnishes

To elevate your Peanut Butter Brownies Recipe, try sprinkling a little flaky sea salt on top right after baking. It punches up the sweetness and adds a subtle crunch that pairs wonderfully with the smooth, creamy peanut butter swirls. For extra flair, a dusting of powdered sugar or a drizzle of melted chocolate can make these brownies party-ready.

Side Dishes

These brownies are fantastic on their own, but they also shine when served alongside a scoop of vanilla ice cream or a dollop of whipped cream. For a fun twist, pair them with fresh berries or a mug of hot coffee or milk for a cozy, comforting snack that feels like a warm hug.

Creative Ways to Present

Try stacking a few squares on a cute dessert plate, garnished with chopped peanuts for added texture. You can also cut them into bite-sized pieces and serve on a platter for easy sharing at parties. For a decadent dessert, sandwich two brownie pieces around peanut butter frosting for a brownie sandwich that’s pure indulgence.

Make Ahead and Storage

Storing Leftovers

If you have leftovers from your Peanut Butter Brownies Recipe, store them in an airtight container at room temperature. They’ll stay moist and delicious for up to 3 days, making it easy to enjoy a quick sweet treat whenever the mood strikes.

Freezing

These brownies freeze beautifully. Wrap individual pieces tightly in plastic wrap or aluminum foil and place them in a freezer-safe bag or container. They’ll keep well for up to 3 months. When you’re ready to indulge again, thaw at room temperature or warm slightly in the microwave.

Reheating

Warm your Peanut Butter Brownies gently in the microwave for about 10 seconds to revive their gooey texture and peanut butter swirls. This little trick makes them taste almost like they’ve just come out of the oven again. Serve warm for maximum comfort!

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter will add a bit more texture and a delightful crunch inside your brownies. Just be sure it’s slightly warmed for easy swirling.

What if I don’t have cocoa powder, can I use melted chocolate?

You can substitute melted chocolate, but keep in mind it will change the texture and richness. Use about 3 ounces of melted bittersweet chocolate for every 1/3 cup of cocoa powder, and reduce the butter slightly.

Can these brownies be made gluten-free?

Yes! Simply replace the all-purpose flour with a gluten-free flour blend designed for baking. It’s best to pick one that contains xanthan gum for structure.

How do I know when the brownies are done baking?

Check by inserting a toothpick in the center; it should come out with a few moist crumbs but not wet batter. Baking time might vary depending on your oven, so start checking around 20 minutes.

Can I double the recipe to make a bigger batch?

Definitely! Just double all the ingredients and bake in a 9×13-inch pan. Adjust the baking time slightly, checking for doneness after 25 minutes.
