Ingredients
Blondie Base
- 8 tablespoons (1 stick) salted butter, melted
- 1 cup dark brown sugar, firmly packed (can substitute with light brown sugar)
- 1 large egg
- 1 ½ teaspoons vanilla extract
- 1 cup all-purpose flour, scooped
- ½ teaspoon baking powder
- ¼ teaspoon salt
Optional Mix-ins
- Heaping ½ cup mix-ins such as butterscotch chips, chocolate chips, or chopped nuts
Instructions
- Preheat Oven and Prepare Pan: Preheat your oven to 350℉ (175℃). Spray an 8”x8” baking dish with non-stick spray and optionally line it with parchment paper to help with easy removal after baking.
- Combine Butter and Sugar: In a large bowl, whisk together the melted butter and brown sugar until thoroughly combined and smooth.
- Add Egg and Vanilla: Whisk in the egg and vanilla extract until the mixture is evenly blended and slightly fluffy.
- Mix Dry Ingredients: Add the all-purpose flour, baking powder, and salt to the wet mixture. Stir gently until just combined without overmixing. Fold in half of the optional mix-ins if using.
- Transfer Batter to Pan: Pour the blondie batter into the prepared baking dish and smooth the surface with a silicone spatula or spoon. Sprinkle the remaining mix-ins evenly over the top.
- Bake: Place in the preheated oven and bake for 20 to 25 minutes or until a toothpick inserted into the center comes out clean. Avoid overbaking to keep the blondies soft and chewy.
- Cool and Serve: Allow the blondies to cool completely on a wire rack; cooling overnight is best for texture and ease of cutting. Once cooled, remove from the pan, cut into bars or triangles, and serve.
Notes
- Mix-ins such as butterscotch chips, chocolate chips, or chopped nuts can be added to customize your blondies.
- Do not overbake, or the blondies will become dry and lose their chewy texture.
- Lining the baking pan with parchment paper makes it easier to lift the blondies out for cutting.
- For best texture, cool completely before slicing; overnight cooling improves consistency.
