- 1 1⁄2 cups packed light brown sugar
- 3 large eggs, lightly beaten
- 1 1⁄4 teaspoons vanilla
- 3⁄4 cup all-purpose flour
- 1⁄4 cup unsweetened dutch cocoa, plus
- 2 tablespoons unsweetened dutch cocoa
- 3⁄4 teaspoon salt
For mint ganache
- 1⁄2 cup heavy cream
- 10 ounces fine-quality white chocolate, chopped

For chocolate ganache

- Make brownie layer: Put oven rack in middle position and preheat oven to 375°F Lightly butter a 13- by 9-inch baking pan and line with 2 crisscrossed sheets of foil, leaving a 2 inch overhang on all sides. Butter foil.
- Melt butter and chocolate with brown sugar in a 3-quart heavy saucepan over moderate heat, stirring occasionally, until smooth. Remove from heat. Whisk in eggs and vanilla until combined. Whisk in flour, cocoa, and salt until just combined.
- Spread batter evenly in baking pan and bake until set and a wooden pick inserted in center comes out with moist crumbs adhering, about 20 minutes. Cool completely in pan on a rack, about 1 1/2 hours.
- Make mint ganache: Bring cream to a simmer in a 2- to 3-quart saucepan and remove from heat. Pour over white chocolate in a bowl. Let stand 1 minute, then whisk until smooth. Stir in crème de menthe and extract and chill, covered, stirring occasionally, until thick, about 1 hour.
- Make chocolate ganache: Bring cream to a simmer in a 2- to 3-quart saucepan and remove from heat. Pour over bittersweet chocolate in a bowl. Let stand 1 minute, then whisk until smooth. Chill, covered, stirring occasionally, until thick, about 30 minutes.
- Assemble layers: Spread mint ganache over top of cooled brownie in a thin even layer using offset spatula, then chill until firm but still slightly sticky, about 30 minutes.
- Spread chocolate ganache over mint and chill until firm, about 2 hours.
- Lift dessert out of pan using foil overhang. Run a heavy knife under hot water and wipe dry, then trim edges of dessert (1/4 inch off each side). Cut dessert into squares and peel from foil.
