Ingredients You’ll Need for the Recipe
- 1 cup creamy peanut butter (no-stir variety works best)
- ¾ cup light brown sugar, packed
- 2 large eggs, room temperature
- 1 tsp vanilla extract
- ½ tsp baking soda
- ¼ tsp salt
- ½ cup chocolate chips (optional)
- Sea salt flakes for topping (optional)
Step-by-Step Baking Instructions
Follow these simple steps for perfect flourless peanut butter blondies:
- Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper for easy removal.
- Mix wet ingredients: In a large bowl, combine peanut butter, brown sugar, eggs, and vanilla extract. Stir until smooth and creamy.
- Add baking soda and salt, then mix again until fully combined.
- Fold in chocolate chips or other add-ins if using.
- Spread batter evenly into the prepared pan. The batter will be thick—use a spatula to smooth it out.
- Bake for 20–25 minutes, or until the edges are set and the center looks slightly underbaked. It will firm up as it cools.
- Cool completely in the pan before slicing into squares.
The brown sugar in these blondies gives them that signature chew, similar to our Maple Brown Sugar Cookies.
