Ultra flavorful Blondies are gooey, chewy, and loaded with chocolate chips or any mix-in your heart desires. One bowl recipe, no mixer required, and made with pantry staples in just 45 minutes. This easy blondie recipe is sure to become a go-to.
1 3/4cups(281 grams) mix-ins of your choice, such as chocolate chips or nuts, divided
Flaky sea salt, for sprinkling
Instructions
Preheat the oven to 350°F. Line an 8 by 8-inch metal pan with foil or parchment paper. Spray with nonstick cooking spray.
In a large microwave-safe bowl, heat the butter in 30-second increments until melted. Add the sugar to the hot butter and whisk to combine. Let cool until just warm.
Add the egg, egg yolk, and vanilla and whisk vigorously until smooth. Stir in the salt, baking powder, and flour with a rubber spatula. Gently stir in 1 1/2 cups (255 grams) of the mix-ins.
Evenly spread the batter into the prepared pan. Top with remaining mix-ins.
For an ooey-gooey center, bake until the edges are lightly golden but the center still jiggles slightly, about 25 minutes. For a firmer center, bake until the edges are golden brown and the center is lightly golden and set, 30-35 minutes. Set pan on wire rack and allow to cool before cutting. Sprinkle with flaky sea salt before serving.

Notes
If the bottoms of your baked blondies are slightly greasy after removing them from the pan, place them on a wire rack overnight covered in plastic wrap. This overnight sit will allow them to set completely.I highly recommend using a metal pan for this recipe. Glass, ceramic, and silicone will take longer to bake through and may cause the edges to overbake before the center is done. Learn more about this in my Glass vs. Metal Baking Pans post here.
