For the best mint julep brownies, keep these tips in mind:
Good-quality chocolate: Use a chocolate you'd enjoy eating to ensure high-quality brownies. A chocolate in bar form will ensure a smooth melt.
Line the pan: Make sure to leave an overhang on two sides for easy brownie removal.
Don't overbake: While it can sometimes be hard to tell when brownies are ready, look for a shiny top that looks set around the edges. If in doubt, insert a wooden pick and look for fudgy crumbs (not wet batter).
Soak evenly: Make sure to soak the brownies evenly with bourbon to infuse the flavor into every bite.
Infuse to taste: Give the mint time to infuse into the cream to reach your desired potency. Keep in mind that the chocolate added will dilute some of the minty flavor.
Cool before cutting: For the cleanest slices, chill the brownies until firm before cutting. Use a sharp knife dipped into hot water between slices for clean cuts.
How To Store Mint Julep Brownies
If you do have any leftover brownies, store in a single layer in an airtight container in the refrigerator for up to five days. You can also freeze them on a lined baking sheet until firm, then transfer to a freezer-safe zip-top bag and freeze for up to two months. Soften at room temperature before serving, although they're also delicious cold.
What To Serve With Mint Julep Brownies
These brownies are decadent all on their own, but to turn them into an over-the-top dessert, serve with a dollop of whipped cream or scoop of ice cream, a drizzle of chocolate sauce, and of course, a pairing of bourbon or a mint julep to stay true to the theme.
