Buttery, chewy blondies loaded with butterscotch chips and chopped nuts, baked in one bowl and ready in under 40 minutes. Rich with brown sugar flavor and just enough crunch — the just enough dessert bar for when you want something a little unexpected.
Preheat the oven to 350F degrees and adjust the oven rack to the middle position. Line a 6-inch cake pan (or loaf pan) with a piece of parchment paper long enough to hang over the sides of the pan.
In a medium mixing bowl, whisk together the brown sugar and melted butter. Add the egg and vanilla and whisk until the egg is well combined.
1/2 cup brown sugar, light or dark, 1/4 cup unsalted butter, melted, 1 teaspoon vanilla extract, 1 large egg, room temperature
Sift (or sprinkle) the flour, baking powder, cinnamon, and salt over the wet ingredients. Stir with a spatula until all of the ingredients are combined. Do not overmix or the blondies may be dense. Gently mix in the chopped nuts, butterscotch chips, and chocolate. Expect a thicker dough. Tip - Rough chop the butterscotch and chocolate chips to make sure every bite has a chip!
½ cup all-purpose flour, ¼ teaspoon baking powder, ½ teaspoon ground cinnamon, 1/4 teaspoon salt, 2 tablespoons butterscotch chips, 1 tablespoon semi-sweet chocolate chips, 1/4 cup salted mixed nuts, roughly chopped
Press the blondie dough evenly into the prepared pan.
Bake for 25 to 30 minutes, or until a toothpick inserted in the middle comes out mostly clean. The edges should be crisp and the center chewy. Cool in the pan set on a wire cooling rack. When ready to serve, use the parchment paper overhang to gently lift the blondies out of the pan.
Cut into any size. If using a 6-inch cake pan, you can get 9 small blondies.
Notes
Serving Size - This is a small batch recipe that can be doubled and baked in an 8x8-inch pan. Increase the bake time by at least 5 minutes.
Mix-Ins - Use any combination you like! Just be cautious not to add too much, or you'll lose the chewy texture.
Nuts - I like to use a salted mixed nut blend, but use any nut you like to eat. For extra flavor, try toasting the nuts first to bring out all the nutty flavor.
Don't Overbake - Or the blondies won't be chewy!
Storage - Keep the brownies covered and store at room temperature for up to 5 days.
Freezing - Place cut blondies in a freezer bag and freeze for up to 3 months. Thaw at room temperature.
Recipe Changes - When I first published this recipe, I used a single egg yolk - which still made delicious blondies. However, after further testing, the recipe has been updated and improved to use a whole egg!
