Butterscotch Brownie
Ingredients
- 8 tablespoons unsalted butter – melted and cooled
- 1 cup light brown sugar – packed
- 1 egg – large
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 cup walnuts – chopped

Instructions
1. Preheat the oven to 350°F (175°C). Line an 8-inch square baking pan with parchment, leaving overhang on two sides for a sling.
2. Melt the butter and let it cool until just warm to the touch, about 5 minutes.
3. In a medium bowl, whisk the brown sugar into the melted butter until glossy and combined, 30–60 seconds.
4. Whisk in the egg and vanilla until the mixture is thick, smooth, and lightened slightly, about 30 seconds.
5. In a separate small bowl, whisk together the flour, baking powder, and salt.
6. Add the dry ingredients to the wet ingredients and stir with a spatula just until no dry flour remains; do not overmix.
7. Fold in the chopped walnuts until evenly distributed.
8. Scrape the batter into the prepared pan and smooth the top.
9. Bake until the edges are set and lightly golden and a toothpick inserted near the center comes out with a few moist crumbs (not wet batter), 20–25 minutes.
10. Cool the pan on a rack for 20–30 minutes. Use the parchment sling to lift the slab out, cool 15 minutes more, then cut into 16 squares and serve.
Butterscotch brownies are chewy, dense dessert bars with a rich caramel-like sweetness from brown sugar and butter, offset by a touch of salt and warm vanilla. Their texture sits between a fudgy brownie and a cookie bar, with a shiny, crackly top and tender middle. Nuts, especially walnuts, add a gentle bitterness and crunch that balance the sweetness and make each bite more complex.
Often called blondies today, butterscotch brownies trace back to mid-20th-century American home baking, when the flavor profile of butter and brown sugar was highlighted without cocoa. Early recipes emphasized simplicity and pantry staples, sometimes billing the bars as lunchbox treats or bake-sale standbys. Over time, variations proliferated—adding chips, different nuts, or spices—but the core appeal has remained the same: a straightforward, buttery bar that celebrates the butterscotch character of brown sugar.
