Grasshopper Bars


Baked Explorations

The Baked Grasshopper Bar was supposed to be a short-lived experiment, a quirky riff or the minty classic 1950s cocktail with which we are slightly obsessed. The impulse to make it came from a cookbook my mom had stashed away, an ancient tome with an emphasis on Midwestern cuisine. Unfortunately, the only thing it seemed to have going for it was page after page of hideous gelatin-infused recipes, each more gruesome than the one before. Still, something about the grasshopper pie was intriguing. Even though the original tastes like medicinal Jell-O, we persevered through countless iterations. And the bar, which was supposed to be just a jokey tongue-in-cheek confection, has endured. The layers work in perfect harmony: thick brownie base, light mint filling, and a dark ganache top. Interestingly enough, this sweet treat works equally well as a classy plated dessert and as an after-school snack.

I rarely advocate underbaking in the quest to develop texture (the raw cookie dough thing was never my cup of tea): however, many of my recipe testers admitted to underbaking the brownie base portion of this recipe by just a few minutes. I tried it, and I admit a fudgier texture is a nice option. The recipe is written for the full baking time, but the final decision is yours.

  • ¾ cups flour
  • ½ teaspoon salt
  • 1 tablespoon dark unsweetened cocoa powder (like Valrhona)
  • 5 ounces good quality dark chocolate (60 to 72%), coarsely chopped
  • 1/3 cup (l stick) butter, cut into 1 inch cubes
  • ¾ cup sugar
  • ¼ cup firmly packed light brown sugar
  • 3 large eggs, at room temperature
  • 1 teaspoons vanilla extract
  • ¾ cup sugar
  • 2 tablespoons flour
  • ¾ cup milk
  • 2 tablespoons heavy cream
  • 1½ stick 8 (¾ cup) butter, softened but still cool, cut into small cubes
  • 3 tablespoons creme de menthe
  • 1 teaspoon peppermint extract
  • 6 ounces good-quality dark chocolate (60 to 72%) coarsely chopped
  • 1 teaspoon light corn syrup
  • ½ cup (1 stick) unsalted butter, softened, cut into cubes


  1. To Make the Brownie Base:

  2. Preheat the oven to 325 degrees F.

  3. Butter the sides and bottom of a glass or light-colored metal 9-by-13-inch pan. Line the bottom with a sheet of parchment paper, and butter the parchment. In a medium bowl, whisk together the flour, the salt, and cocoa powder.

  4. Configure a large size double boiler. Place the chocolate and the butter in the bowl of the double boiler and stir occasionally until the chocolate and butter are completely melted and combined. Turn off the heat, but keep the bowl over the water of the double boiler and add both sugars. Whisk the sugars until completely combined. Remove the bowl from the pan. The mixture should be at room temperature.

  5. Add three eggs to the chocolate/butter mixture and whisk until just combined. Add the vanilla and stir until combined. Do not overheat the batter at this stage or your brownies will be cakey.

  6. Sprinkle the flour/cocoa/salt mix over the chocolate. Using a spatula (do not use a whisk) fold the dry ingredients into the wet until there is just a trace amount of the flour/cocoa mix visible

  7. Pour the batter into the prepared pan, smooth the top with an offset spatula, and bake for approximately 12 to 15 minutes, rotating halfway through the baking time. The brownies should be just a tad underdone (not too gooey, but ideally, just 1 minute from being cooked through completely). A tooth-pick inserted into the brownies at an angle should contain a few loose crumbs. Remove the brownies from the oven and let cool completely while you make the crème de menthe filling.

  8. To Make the Buttercream:

  9. In a medium heavy-bottomed saucepan, whisk the sugar and flour together. Add the milk and cream and cook over medium heat, whisking occasionally until mixture comes to a boil and has thickened. 5 to 7 minutes.

  10. Transfer the mixture to the bowl of an electric mixer fitted with the paddle attachment. Beat on high speed until cool. Reduce the speed to low and add the butter and mix until thoroughly incorporated. Increase the speed to medium-high and beat until filling is light and fluffy.

  11. Add the crème de menthe and peppermint extract and mix until combined. If the filling is too soft, chill slightly in the refrigerator and then mix again until it is the proper consistency.

  12. If the filling is too firm, place the bowl over a pot of simmering water and re-mix to proper consistency. Spread the filling evenly across the top of the brownie layer and place the pan in the refrigerator, for a minimum of 45 minutes, while you make the chocolate glaze.

  13. To Make the Chocolate Glaze:

  14. In a large non-reactive metal bowl, combine the chocolate, corn syrup, and butter. Set the bowl over a saucepan of simmering water and cook, stirring with a rubber spatula, until the mixture is completely smooth. Remove the bowl from the pan and stir vigorously for 1 minute to release excess heat.

  15. Pour the mixture over the chilled crème de menthe layer and use an offset spatula to spread it into an even layer. Place the pan back in the refrigerator for 1 hour, or until the glaze hardens.

  16. Remove the pan from the refrigerator, wait about 15 minutes for the glaze to soften slightly, and cut the bars with a warm knife. Cut into squares and serve immediately.

  17. The bars can be stored in the refrigerated, tightly covered, for up to 4 days.
