Description
Chewy, butterscotchy bars with the deep flavor of browned butter and dark chocolate with about 1/3 less sugar than a traditional blondie recipe.
Ingredients
- Cooking spray for the pan
- 1 stick butter (113 g)
- 1/3 cup powdered sugar (40 g)
- 1/3 cup light brown sugar (66 g)
- 1/2 tsp baking powder
- 1/2 tsp salt
- 1 large whole egg plus 1 egg yolk
- 1 tsp vanilla paste
- 1 cup all-purpose flour (130 g)
- 1/2 cup dark chocolate chips (85 g)
Instructions
- Preheat the oven to 350F (180 C).
- Lightly spray an 8″x8″ pan with cooking spray, then cut a piece of parchment to line the bottom and sides of one side. Spray over the top of this piece of parchment, then cut another one to go across the remaining 2 sides of the pan.
- Melt the butter over low heat in a small pan until the foam starts to subside and there are brown flecks in the bottom of the pan. On low heat, this will take about 10 minutes.
- While the butter is browning, fill the bottom of a double boiler with about 1″ of water, then bring it to a boil.
- Use a whisk to mix the sugars, baking powder, salt, whole egg and the egg yolk in the top of a double boiler.
- Lower the water to simmer, then set the top pot over the water, stirring constantly for about 4 minutes. In this time, the mixture will get thinner, paler, and all of the sugar will dissolve.
- Once the butter has browned, set it in a bowl to cool slightly.
- Whisk the egg/sugar mix into the butter. If it splits, keep whisking. As it cools, it will come back together.
- Allow the butter mix to cool until it’s thick and no longer warm to the touch. It will be noticeably thicker and glossy.
- Fold in the flour with a baking spatula until the flour disappears.
- Quickly fold in the chocolate chips, then smooth the mixture in the pan.
- Bake for 18-20 minutes until the edges are browning and the middle is just barely no longer jiggling.
Notes
No double boiler?: Fill a 1 qt pot with 1″ of water. Bring a water to a simmer, then nestle a stainless steel mixing bowl in the pot as a homemade double boiler.
Nuts: Add your favorite chopped nuts to the mix if you’d like. 1/2 cup of walnuts or pecans are especially good.
Marble top: fold in the chocolate chips when the batter is still warm. This will melt some of the chocolate, giving you a streaky easy marbled top.
