Fudgy Oat Brownies with Toasted Walnuts

Steps

1. Preheat the oven to 350°F (175°C) and line an 8-inch square pan with parchment.
2. Spread the walnuts on a small baking sheet and toast in the oven for 6–8 minutes until fragrant; let cool.
3. Melt the butter in a saucepan over low heat, then pour it into a large bowl.
4. Add the granulated sugar to the warm butter and whisk to combine.
5. Add the brown sugar to the bowl and whisk until smooth.
6. Add the unsweetened cocoa powder to the bowl and whisk until glossy, then let cool for 5 minutes.
7. Whisk in the eggs one at a time, then the vanilla and salt, beating about 1 minute until thick and shiny.
8. In a separate bowl, stir together the flour, oats and baking powder to make the dry mix.
9. Fold the dry mix into the chocolate batter just until no dry streaks remain.
10. Fold in half of the toasted walnuts and half of the chocolate chips.
11. Spread the batter in the pan and scatter the remaining half of the walnuts and the remaining half of the chocolate chips over the top.
12. Bake for 25–28 minutes, until the edges are set and a toothpick inserted in the center comes out with only a few moist crumbs, not wet batter.
13. Cool in the pan on a rack for at least 45 minutes, then lift out and cut into 12 bars.
