How to Make Peanut Butter Blondies

Step 1: Prepare the Pan and Preheat the Oven

Preheat the oven to 350°F (177°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang for easy removal.

Step 2: Combine Wet Ingredients

In a large bowl, whisk together the melted butter and brown sugar. Whisk in the peanut butter, then the eggs, egg yolk, and vanilla extract until smooth.

Step 3: Add Dry Ingredients

Add the flour, baking powder, and salt to the wet ingredients. Fold the batter together with a rubber spatula until just combined. The batter will be thick.

Step 4: Add Reese’s Pieces

Fold in the Reese’s Pieces. Spread the batter evenly into the prepared pan. Sprinkle a few extra Reese’s Pieces on top, if desired.

Step 5: Bake

Bake for 30 minutes, or until a toothpick inserted into the center comes out with only a few moist crumbs. Be careful not to overbake.

Step 6: Cool and Cut

Allow the blondies to cool completely in the pan on a wire rack. Once cooled, lift them out using the parchment paper overhang and cut into squares.

Step 7: Serve and Store

Serve the blondies immediately or store them in an airtight container at room temperature for up to 1 week.

Pro Tips for Making the Recipe

Use processed peanut butter: Avoid natural peanut butters as they can make the blondies dry and crumbly.
Don’t overmix the batter: Overmixing can lead to tough blondies.
Check for doneness carefully: Blondies can overbake easily, so check them frequently towards the end of baking.
Cool completely before cutting: This will ensure clean cuts and prevent the blondies from falling apart.

How to Serve

Dessert: Enjoy these blondies as a sweet treat after a meal.
Snack: They’re perfect for a midday snack or anytime you’re craving something sweet.
Party Treat: Cut them into smaller squares for a crowd-pleasing party dessert.

Make Ahead and Storage

Storing Leftovers

Store leftover blondies in an airtight container at room temperature for up to 1 week.

Freezing

Baked and cooled blondies freeze well for up to 3 months. Thaw them overnight in the refrigerator and bring them to room temperature before serving.
