The best blondie recipe! These blondies are buttery and chewy with a shiny top and rich vanilla flavor. They are easy to make in one bowl with 8 ingredients.
Line an 8x8” square baking pan with parchment paper and lightly grease. Set aside.
In a small bowl, mix together flour, baking powder, and salt. Set aside.
In a large, microwave safe bowl (glass) melt butter.
Add brown sugar and granulated sugar and stir until combined.
Add eggs and vanilla to the butter/sugar mixture and stir until mixture is smooth.
Add dry ingredients and stir until all the ingredients are just combined, be careful not to over-mix the batter.
Fold in preferred mix-ins until evenly distributed.
Spread the batter evenly in the prepared baking dish.
Bake for 25-30 minutes, or until the top is golden-brown and shiny (If you like fudgier blondies bake for 25 minutes, for cakier blondies bake for 30 I recommend 25).
Place baking pan on a wire cooling rack and let the bars cool in the pan for at least 30 minutes (preferably longer, they hold up better as they cool).
Use the parchment paper to lift the cookie bars out of the pan, then cut into squares and serve.

Notes
Ingredient Substitutions
SaltedButter. Unsalted butter works well in this recipe.
Granulated sugar. you can use organic cane sugar instead of white sugar.
LightBrown sugar. If you like a deeper, molasses taste, use dark brown sugar.
All-purpose flour. For a gluten-free version, use an all-purpose gluten-free baking flour.
FineSea salt. If you use table salt (iodized) I recommend halving the salt.
Vanilla extract. This ingredient is key in this recipe. You could replace it with vanilla bean paste or the seeds of one vanilla bean, if necessary.
Mix-ins. You can choose your favorite mix-ins - or leave them out entirely because these blondies taste amazing without them. Suggestions include (but are not limited to): chocolate chips, white chocolate chips, dried fruit (cranberries, cherries etc.), nuts (pecans, walnuts), cinnamon chips, etc.
