Ingredients
Brownie Batter
- 1 box (18–19 oz) chocolate brownie mix, no mix-ins
- 1/2 cup neutral oil (canola or vegetable)
- 1/3 cup buttermilk, warmed
- 2 large eggs, at room temperature
- 2 teaspoons instant coffee or espresso powder
- 2 teaspoons pure vanilla extract
- 3/4 teaspoon fine sea salt
- 1 tablespoon pure maple syrup
- 1 cup semi-sweet chocolate chips, divided
Pan & Finish
- nonstick baking spray or softened butter, for the pan
- 1 tablespoon unsweetened cocoa powder, for dusting pan
- flaky sea salt, for finishing
Instructions
Preparation Steps
- Position a rack in the center of the oven and heat to 325°F. Lightly grease an 8-inch square pan with spray or butter, then dust the bottom and sides with cocoa powder; tap out any excess.
- Microwave the buttermilk just until warm to the touch (10–15 seconds). Stir in the instant coffee and vanilla until dissolved; set aside.
- In a large bowl, briskly whisk the eggs, oil, maple syrup, and sea salt until glossy and well emulsified, about 30 seconds.
- Whisk the warm coffee–vanilla buttermilk into the egg mixture until smooth.
- Sprinkle the brownie mix over the wet ingredients and fold with a spatula just until no dry pockets remain. Fold in 3/4 cup of the chocolate chips. Let the batter rest for 5 minutes to hydrate.
- Scrape the batter into the prepared pan and smooth the top. Scatter the remaining 1/4 cup chips over the surface.
- Bake until the edges are set, the center has a slight jiggle, and a toothpick inserted 2 inches from the edge comes out with moist crumbs, 43–48 minutes. Rotate the pan once halfway through baking.
- Cool the pan on a rack for 20 minutes, then finish with a light sprinkle of flaky sea salt. Cool an additional 15–30 minutes before slicing with a sharp knife, wiping the blade between cuts.
Notes
For ultra-clean edges, chill the brownies for 20–30 minutes after the initial cooling, then cut. Store airtight at room temperature for up to 3 days or freeze (well-wrapped) for up to 2 months.
