Ingredients

  • 1/2 cup unsalted butter - melted
  • 1 cup brown sugar
  • 1/2 cup crunchy peanut butter - or use creamy peanut butter
  • 2 large eggs
  • 1 Tablespoon vanilla
  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon cornstarch
  • 1/2 teaspoon kosher salt
  • 1 cup semi-sweet chocolate chips - plus more for the top

Instructions

  • Preheat oven to 350 degrees. Prepare an 8x8 baking dish with parchment paper.
  • In a mixing bowl, melt butter. Add peanut butter and stir well. Then add brown sugar, eggs, and vanilla, and mix again.
    1/2 cup unsalted butter, 1/2 cup crunchy peanut butter, 1 cup brown sugar, 2 large eggs, 1 Tablespoon vanilla
  • In another bowl, combine flour, baking soda, cornstarch, and salt. Pour into wet ingredients, and stir until just combined. Fold in chocolate chips.
    1 1/2 cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon cornstarch, 1/2 teaspoon kosher salt, 1 cup semi-sweet chocolate chips
  • Spoon mixture into prepared baking dish, spreading evenly. Top with some extra chocolate chips and bake for approximately 25 - 30 minutes, or until bars are just done in the center.
  • Remove from oven. Let cool and then cut into 12 equal pieces.

Notes

  1. Using parchment paper in the baking dish makes it easy to remove the blondies from the pan. Just lift them out and slice.
  2. If you like gooier blondies, bake for less. If you like them firmer, baking longer. You may want to cover the tops for part of the baking time.
  3. You can adapt the mix-ins for this recipe. Use different chips, or nuts, or m&ms, etc. You can also use a crunchy peanut butter or other nut butter.
  4. Tailor these for the holidays and use colored m&ms to match the event.
Make ahead tip: Prep the cookie dough the day before, and then just press into the baking dish when ready to bake. Makes dessert quick and easy!
Freezing tip: You can freeze the dough for up to three months. Just remove and press into pan when softened.
