  • 1 1/2 cups (180 g) all-purpose flour: For gluten-free options, substitute with almond flour or a 1:1 gluten-free blend.
  • 1 teaspoon baking powder: This helps the blondies rise and achieve that perfect texture.
  • 1/2 teaspoon salt: Enhances the flavors; use sea salt for a more refined taste.
  • 12 tablespoons (3/4 cup, 170 g) unsalted butter: Melted and slightly cooled; you can also use coconut oil for a dairy-free version.
  • 1 cup (213 g) packed light brown sugar: Adds moisture and a hint of caramel flavor.
  • 1/2 cup (100 g) granulated white sugar: Balances the richness of the brown sugar.
  • 1/2 cup (135 g) smooth peanut butter: The star of the show! Any nut butter can be used for a twist.

Step-by-Step Instructions

Ready to bake? Let’s get into the nitty-gritty of making these delightful blondies!

  1. Prep your oven and pan: Preheat your oven to 350°F (175°C). Line a 13 x 9-inch baking pan with foil, leaving an overhang for easy removal later. Spray with cooking spray or use parchment paper for a non-stick surface.
  2. Combine dry ingredients: In a medium bowl, whisk together flour, baking powder, and salt. Make a well in the center of the dry ingredients.
  3. Mix wet ingredients: In a separate bowl, whisk together melted butter, both sugars, vanilla extract, eggs, and peanut butter until smooth.
  4. Combine wet and dry ingredients: Pour the wet mixture into the dry ingredients. Using a rubber spatula, gently fold until just combined—be careful not to overmix!
  5. Add mix-ins: Fold in the chocolate chips and Reese’s Pieces until evenly distributed. Spread the batter evenly into the prepared pan, smoothing the top with a spatula.
  6. Bake: Bake in the preheated oven for 22-25 minutes, or until the top is shiny, cracked, and light golden brown. The blondies may appear slightly underdone in the center—this is perfect!
  7. Cool & cut: Allow the blondies to cool in the pan on a wire rack. Once cooled, use the foil overhang to lift them out of the pan and cut into squares.

Expert Tips for Perfect Blondies

[

Let’s ensure your blondies are a smashing success! Here are some pro tips to keep in mind:

  • Room Temperature Ingredients: Make sure your eggs and butter are at room temperature for optimal mixing.
  • Don’t Overmix: Overmixing can lead to dense blondies. Gently combine ingredients until just mixed.
  • Check for Doneness: Use a toothpick to check for doneness; it should come out with a few moist crumbs, not wet batter.
  • Let Them Cool: Allow the blondies to cool completely before cutting for cleaner edges.
  • Storage Tips: Store in an airtight container at room temperature for up to a week, or freeze for extended freshness.
  • Experiment with Add-ins: Mix in nuts, dried fruits, or other candies to customize your blondies!
  • Use Quality Ingredients: High-quality chocolate and peanut butter make a world of difference in flavor.
  • Adjust Sweetness: If you prefer less sweetness, reduce the sugar slightly without compromising texture.
  • Try Different Nut Butters: Almond, cashew, or sunflower butter can all work beautifully in this recipe!

Common Mistakes and Troubleshooting

Even the best bakers can run into issues. Here’s how to troubleshoot common mistakes:

  • Blondies are too dry: This can happen if they’re overbaked. Make sure to check them at the minimum baking time.
  • Blondies are too gooey: If they’re still too wet in the center, they might need a few extra minutes in the oven.
  • Uneven baking: Ensure your oven is properly calibrated and use the middle rack for even heat distribution.

Delicious Variations

Feel free to get creative with these blondies! Here are some fun variations to try:

  • Chocolate Chip & Walnut: Add 1 cup of chopped walnuts for a crunchy twist.
  • Peanut Butter Swirl: Swirl extra peanut butter on top before baking for an added flavor boost.
  • Mint Chocolate: Incorporate mint chocolate chips for a refreshing flavor change.
  • Sea Salt Caramel: Drizzle caramel sauce over the top and sprinkle with sea salt for a decadent finish.

Storage and Make-Ahead Instructions

Want to prepare these blondies ahead of time? Here’s how to store and make them for later:

  • Room Temperature: Store cooled blondies in an airtight container at room temperature for up to a week.
  • Freezing: Freeze individual squares wrapped in plastic wrap and then in foil for up to 3 months. Thaw at room temperature when ready to enjoy.
  • Dough Storage: You can freeze the unbaked dough for up to a month. Just thaw in the fridge overnight before baking.
