Units Scale
  • 1/2 cup butter, melted
  • 1 1/2 cup brown sugar
  • 2 eggs, room temperature
  • 2 tsp vanilla
  • 1 1/4 cup all purpose flour
  • 1 tsp baking powder
  • 3/4 cup smooth peanut butter + 1/4 cup for topping
  • 1/2 tsp kosher salt + 1/2 tsp for topping
  • 1/4 cup caramel sauce
  • 1/4 cup dry roasted peanuts, coarsely chopped


  1. In a bowl, combine the melted butter, brown sugar, eggs, vanilla extract and 3/4 cup peanut butter. Stir until combined.
  2. In a separate bowl, combine the dry ingredients (flour, baking powder and 1/2 tsp kosher salt).
  3. Fold the dry ingredients into the batter.
  4. Line a 9″x9″ square cake pan or casserole dish with parchment paper.
  5. Spread the batter evenly into the pan.
  6. Heat the remaining 1/4 cup peanut butter in the microwave until thinned.
  7. Drizzle the peanut butter and caramel sauce over the top of the batter.
  8. Swirl with a butter knife.
  9. Top with dry roasted peanuts.
  10. Bake at 350F for 30-35 minutes.
  11. Remove from oven and immediately sprinkle with 1/2 tsp kosher salt.


  • Bringing cold eggs to room temperature quickly: If you need to bring your eggs to room temperature quickly for this recipe, fill a bowl with hot water from your tap and place the eggs in it for about 5 minutes.
  • Omitting the caramel sauce: Caramel not your thing? No problem! Simply leave it off or substitute it with a 1/4 cup of something else, like marshmallow fluff.
  • Testing for doneness: Blondies have reached the perfect level of doneness when a toothpick/cake tester comes out with a few baked crumbs. Because blondies are a moist treat with a fair amount of fatty ingredients, a completely clean toothpick indicates they’ve likely been overbaked.
  • Making a large batch: If you’d like to make a larger batch of these blondies, you can double the recipe and bake them in a 9″x13″ casserole dish. Simply increase the bake time by 5-15 minutes or until done.
  • Storage: Blondies can be kept in an air tight container at room temperature for about 3 days.
