These small batch blondies are rich, chewy, and packed with chocolate chips and crunchy walnuts. It's an easy recipe and the perfect dessert for one or two.
Preheat oven to 350°F (177°C). Lightly butter a 5x5-inch baking dish and set aside.
In a medium bowl, whisk together melted butter and brown sugar until smooth. Add the egg and vanilla; whisk until fully combined.
In a small bowl, mix flour, baking powder, and salt. Stir into the wet mixture just until combined.
Fold in chocolate chips and chopped walnuts.
Pour the batter into the prepared dish and spread evenly. Place on a rimmed baking sheet and bake for 25–28 minutes, or until the edges are set and a toothpick comes out clean.
Let cool for 20 minutes. Run a knife along the edges to loosen, then cut into 4 squares. Serve warm or let cool completely.
Notes
Cool the Butter: Let the melted butter cool slightly before mixing to prevent scrambling the egg.
Evenly Mix Dry Ingredients: Stir the flour, baking powder, and salt together first to evenly distribute the leavening.
Don’t Overmix: After adding the dry ingredients, mix just until combined. Overmixing can make the blondies dense.
