How to Make Peanut Butter Blondies Recipe

Step 1: Prepare Your Pan and Oven

Preheat your oven to 350 degrees F. This sets the perfect temperature to bake your blondies evenly. Line an 8×8 baking pan with parchment paper or grease it well to ensure your blondies don’t stick—this little step makes for easy release and clean edges!

Step 2: Melt Butter and Combine with Peanut Butter and Sugar

In a microwave-safe bowl, melt the 6 tablespoons of unsalted butter. This usually takes about 1 minute but keep an eye so it doesn’t scorch. Once melted, stir in the peanut butter until it melts together smoothly with the butter, creating one silky mixture. Then whisk in the brown sugar with your fork or whisk; this melding of fats and sugar will give you a glossy base that promises moist, chewy blondies.

Step 3: Add Eggs and Vanilla

Crack in one large egg and add the teaspoon of vanilla extract. Whisk them thoroughly into the mixture until the batter looks shiny and fully blended. This step is crucial as it adds moisture and helps bind the ingredients for that perfect chewy texture.

Step 4: Incorporate Dry Ingredients

Sprinkle in the flour, baking soda, and salt over your wet mixture. Gently fold everything together with a spatula or spoon, mixing until just combined for a tender crumb—be careful not to overmix, which can make the blondies tough.

Step 5: Press Batter into Pan and Add Toppings

Transfer the batter to your prepared pan. Press it down evenly to form one smooth layer—using your hands here can be the easiest way to get a uniform surface. If you like an extra crunch and a pop of texture, sprinkle chopped peanuts generously over the top now.

Step 6: Bake Until Golden and Set

Pop the pan in the oven and bake for 22 to 24 minutes. Look for browned edges and slightly puffed tops as a sign the blondies are done. Resist the urge to cut immediately; once they’ve cooled completely, you’ll have perfectly set bars that slice cleanly and taste even more delicious.

How to Serve Peanut Butter Blondies Recipe

The image shows about fifteen square-shaped peanut butter bars arranged closely on white parchment paper over a white marbled surface. Each bar has a golden-brown color with a slightly rough texture and is topped with small pieces of chopped peanuts scattered unevenly on the tops. The bars look soft and moist, with crumbs visible around and between them on the parchment paper. The edges of most bars are clean but some appear slightly broken or uneven.

Garnishes

These blondies are scrumptious on their own, but garnishing can elevate their charm. Think a light drizzle of melted chocolate or a sprinkle of flaky sea salt to highlight that peanut butter sweetness. Even a dollop of whipped cream or a scoop of vanilla ice cream turns this treat into a show-stopper dessert.

Side Dishes

Pair your Peanut Butter Blondies Recipe with a cold glass of milk, a warm cup of coffee, or even a rich hot chocolate for a comforting snack or after-dinner dessert. Fresh fruit like berries or banana slices also complements the richness beautifully and adds a fresh burst of flavor.

Creative Ways to Present

Consider cutting these blondies into bite-size squares and serving them on a platter for parties or packing them into pretty boxes as gifts. For a twist, sandwich two blondies together with chocolate or peanut butter frosting to create peanut butter blondie sandwiches that will wow any guest.

Make Ahead and Storage

Storing Leftovers

Store your blondies in an airtight container at room temperature, and they will stay moist and delicious for about 3 to 4 days. If you want to keep them fresh longer, the fridge is your friend, though this might firm them up slightly—just let them come to room temperature before enjoying.

Freezing

These blondies freeze wonderfully! Wrap individual pieces in plastic wrap and place them in a freezer-safe bag or container. You can keep them frozen for up to 3 months without sacrificing that chewy texture and intense peanut butter flavor.

Reheating

To enjoy your Peanut Butter Blondies Recipe warm after storing, pop them in the microwave for about 10 to 15 seconds or wrap in foil and warm briefly in a preheated oven. This brings back that gooey, fresh-baked sensation that’s simply irresistible.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Using crunchy peanut butter will add little pockets of texture throughout your blondies, which some people love. Just be sure to mix it well with the melted butter so the texture is spread evenly.

Can these blondies be made gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free flour blend. Just make sure it has xanthan gum or another binding agent to mimic gluten’s effect for the best chewy texture.

Is it possible to reduce the sugar in this recipe?

You can reduce the brown sugar slightly, but keep in mind the sugar contributes to moisture and browning. Reducing too much might affect texture and flavor, so try cutting it by a tablespoon or two and see how you like it.

Can I add chocolate chips or other mix-ins?

Definitely! Chocolate chips, white chocolate chunks, or even dried fruit like cranberries work beautifully in this recipe. Toss them in with the dry ingredients before baking for a fun twist.

What’s the best way to cut these blondies without crumbling?

Make sure your blondies are completely cool before slicing—this is crucial for clean, neat squares. Use a sharp knife and wipe it clean between cuts to keep edges tidy and prevent crumbling.
