Peanut Butter Blondies Recipe

Introduction

Peanut Butter Blondies are a rich and chewy treat packed with the delicious flavors of peanut butter, chocolate, and Reese’s Pieces. These bars offer a perfect balance of sweetness and texture, making them an irresistible dessert or snack for peanut butter lovers.

Ingredients

• 2/3 cup unsalted butter (170 grams)
• 3/4 cup peanut butter (about 270 grams)
• 2 cups light brown sugar (420 grams)
• 2 teaspoons vanilla extract
• 3 large eggs
• 2 cups all-purpose flour (250 grams)
• 1/4 teaspoon salt
• 3/4 cup Reese’s Pieces (about 140 grams)
• 3/4 cup chocolate chips (about 120 grams)

Instructions

1. Step 1: Preheat your oven to 350°F (180°C). Line a 9×13 inch pan with parchment paper, leaving an overhang, or lightly grease the pan.
2. Step 2: In a large microwave-safe bowl, melt the butter and peanut butter together. Stir until smooth once almost melted.
3. Step 3: Whisk the brown sugar into the peanut butter mixture. Then add the eggs and vanilla extract, whisking until fully combined with no visible egg pieces.
4. Step 4: Gently fold in the flour and salt, mixing just until there are no streaks or lumps of flour left.
5. Step 5: Fold in the Reese’s Pieces and chocolate chips evenly throughout the batter.
6. Step 6: Pour the batter into the prepared pan and spread it out smoothly on top.
7. Step 7: Bake for about 30 minutes, or until the top looks set and a toothpick inserted in the center comes out clean or with a few moist crumbs. For firmer bars, bake up to 35 minutes.
8. Step 8: Allow the blondies to cool completely in the pan. Use the parchment overhang to lift them out, then slice with a sharp knife. If you greased the pan, simply slice directly inside the pan.

Tips & Variations

• Use smooth peanut butter for best texture, though crunchy works as well. Avoid homemade or natural peanut butter as it may separate during baking.
• Customize your bars by mixing in your favorite combinations such as peanut butter chips, chopped peanut butter cups, or extra chocolate chips.
• For a smaller batch, use an 8×8 inch pan with adjusted ingredient amounts and bake around 25 minutes.

Storage

Store the blondies in an airtight container at room temperature for up to 4 days. For longer storage, freeze baked and cooled blondies in an airtight container for up to 2 months. Place sheets of wax paper between the bars to prevent sticking. Thaw frozen blondies in the refrigerator before serving.

FAQs

Can I use natural peanut butter in this recipe?

Natural peanut butter is not recommended because it tends to separate, which can affect the texture and consistency of the blondies.

How do I know when the blondies are done baking?

The blondies are done when the top is set and a toothpick inserted in the center comes out clean or with just a few moist crumbs. If you prefer less gooey bars, bake an additional 5 minutes.

Ingredients

Scale 1x2x3x

Main Ingredients

• 2/3 cup unsalted butter (170 grams)
• 3/4 cup smooth peanut butter (about 270 grams)
• 2 cups light brown sugar (420 grams)
• 2 teaspoons vanilla extract
• 3 large eggs
• 2 cups all-purpose flour (250 grams)
• 1/4 teaspoon salt

Mix-ins

• 3/4 cup Reese’s Pieces (about 140 grams)
• 3/4 cup chocolate chips (about 120 grams)

Instructions

1. Preheat Oven: Preheat your oven to 350°F (180°C). Prepare a 9×13 inch baking pan by lining it with parchment paper, leaving an overhang on the sides for easy removal, or alternatively lightly grease the pan.
2. Melt Butter and Peanut Butter: In a large microwave-safe bowl, melt together the unsalted butter and peanut butter. Stir until completely smooth once almost melted.
3. Add Sugar and Eggs: Whisk the light brown sugar into the peanut butter mixture. Then whisk in the eggs and vanilla extract until the mixture is smooth and no pieces of egg remain visible.
4. Incorporate Dry Ingredients: Gently fold the all-purpose flour and salt into the wet mixture, stopping as soon as there are no visible flour streaks or lumps to avoid overmixing.
5. Add Mix-ins: Fold in the Reese’s Pieces and chocolate chips evenly throughout the batter.
6. Transfer to Pan: Spoon or pour the batter into the prepared baking pan and spread it out smoothly with a spatula.
7. Bake: Bake in the preheated oven for about 30 minutes, or until the top looks set and a toothpick inserted in the center comes out clean or with a few moist crumbs. For less gooey blondies, bake for 35 minutes.
8. Cool and Slice: Allow the blondies to cool in the pan. When ready to slice, lift the blondies out using the parchment overhang or slice directly in the pan if greased. A sharp, thin knife works best. Cooling for about 2 1/2 hours is ideal for clean slicing, though the chips will remain melty.

Notes

• Peanut Butter: Use smooth peanut butter for best results. Crunchy peanut butter is acceptable but avoid homemade or natural varieties as they can separate and cause inconsistent textures.
• Mix-ins: You can customize the mix-ins by using 1 1/2 cups total of your favorites like peanut butter chips, chocolate chips, Reese’s Pieces or chopped peanut butter cups.
• Smaller Batch: For an 8×8 inch pan, adjust ingredients accordingly and bake for about 25 minutes. Ingredients: 1/3 cup butter, 1/4 cup + 2 tbsp peanut butter, 1 cup brown sugar, 1 tsp vanilla, 1 large egg + 1 egg yolk, 1 cup flour, pinch of salt, 6 tbsp Reese’s Pieces, 6 tbsp chocolate chips.
• Storage: Store blondies in an airtight container at room temperature for up to 4 days. You can freeze baked and cooled blondies for up to 2 months; separate layers with wax paper to prevent sticking. Thaw in the fridge before serving.
