Ingredients
Units
- 1 tablespoon ground instant coffee
- 1 tablespoon water
- 1 teaspoon vanilla extract
- 2 cups firmly packed brown sugar
- 3/4 cup (180g) unsalted butter
- 2 large eggs, at room temperature
- 2 cups (280g) all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 5 oz. (140g) white chocolate chips or chunks
- 3/4 cups (100g) walnuts, coarsely chopped (you can toast them lightly for a better flavor)
Instructions
- Preheat the oven to 350ºF/180°C.Â
- Butter a 9-inch square cake pan and line the bottom with parchment paper.
- Combine coffee and water in a small saucepan and stir until dissolved.Â
- Over low heat, add sugar and butter and stir until butter melts.Â
- Turn off the heat and let the mixture cool to room temperature, stirring occasionally. You can transfer it to a bowl to speed it up.
- Add eggs and coffee liqueur to the butter mixture and whisk to combine.
- Sift flour, baking powder, and salt directly into the butter mixture and stir to blend.Â
- Stir in chocolate and nuts.
- Bake until a tester comes out almost clean, about 35 minutes. Do not overbake, or they will be tough.Â
- Cool in the pan on a wire rack for at least 15 minutes.Â
- Loosen sides with a knife, turn onto a plate, peel off the paper, cut into wedges and serve.
Notes
- Freezing: you can freeze them for up to a month. I recommend cutting them first when they are cooled down, wrapping them in plastic wrap and then in aluminum paper.Â
- Variation:Â this is my sophisticated adult version,
Add a tablespoon (or two) of coffee liqueur, such as Kahlua, to the batter, the drizzle, or both.
Use different nuts, a mix of hazelnuts and pecans is my favorite.
Add dark, intense chocolate chips, like Ghirardelli 60% Cacao Bittersweet Chocolate Chips.
