I love chocolate and mint together. LOVE THEM! So I’m always on the look-out for a good recipe that combines the two.
This certainly fit the bill! Just a few notes for you though. The brownie is pretty thin. I baked mine a little too long, so it was a bit crispier than I would have liked. I would recommend checking it about 15 minutes in.
And y’all. Please use good white chocolate. Since this is a white chocolate ganche, so basically just white chocolate and cream, the flavor is really important. Yes, I got mine at William Sonoma and spent way too much. Whatever, it tasted good. You could also check at somewhere like World Market. Just make sure it actually says “white chocolate” on the package. Nothing else. Just that phrase. I beg of you.
And the final note. The ganache is pretty sticky. Which is fine if you don’t have to transport it. But if you need to stack these at all, cut the cream by up to half. No more than that. And if you’re just going to serve them at home, and don’t need to take them to the office, like I did, the recipe as-is should be fine.
Grasshopper Squares [aka Creme de Menthe Brownies]
Adapted from Gourmet, December 2005 and smittenkitchen.com
Makes anywhere from 72 normal-sized brownies to 117 one-inch squares (I think the perfect size)
For brownie layer
1 1/2 sticks (3/4 cup) unsalted butter
10 1/2 oz fine-quality bittersweet chocolate (not extra-bitter or unsweetened and no more than 60% cacao if marked), finely chopped
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 plus 2 tablespoons unsweetened Dutch-process cocoa powder
3/4 teaspoon salt
For mint ganache
1/2 cup heavy cream (this will make a stickier ganache…you can use half of this, for more of an “al dente” bite to it)
10 oz fine-quality white chocolate, chopped (please please please use the good stuff. It’s worth the splurge)
1 tablespoon green crème de menthe
1 teaspoon peppermint extract
For chocolate ganache
1 cup heavy cream (see note for mint ganache)
10 oz fine-quality bittersweet chocolate (not unsweetened), finely chopped
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.
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.
