Preheat the oven to 350°F.Grease the bottom of an 8x8-inch pan and line it with parchment paper.
Brown or heat the butter. Here is our step-by-step guide on how to brown butter. The key is, whether you're browning the butter or not, the butter needs to be hot enough to melt the chocolate easily! 1 cup unsalted butter
Pour the hot butter over the top of the chopped chocolate, cocoa powder, and espresso powder mixture and stir to melt. Set aside to cool.
¾ cup browned butter, 4 ounces bittersweet or dark chocolate bar, ⅓ cup Dutch processed cocoa powder, 2 teaspoons instant espresso
In a bowl, combine brown sugar, the eggs, and an egg yolk. With a hand mixer, mix until pale and fluffy, about 3-5 minutes.
1 ¼ cups brown sugar , 2 large eggs , 1 large egg yolk
Carefully stream the melted chocolate and butter mixture into the egg mixture, whisking constantly. Add the vanilla extract, and continue mixing until completely combined.
1 tablespoon vanilla extract
Add in the all purpose flour and salt, and switch to a rubber spatula to gently mix. Once the dry ingredients are almost all the way combined (there will still be a few streaks of flour), fold in the chocolate chunks or chips and most of the fresh sweet cherries, reserving some for the top.
1 cup all purpose flour, 1 teaspoon kosher salt, 1 ¾ cups sweet cherries, ¾ cup chocolate chunks or chips
Pour the brownie batter into a prepared pan, and spread it evenly with an offset spatula. Add dollops of cherry preserves over top of the brownies, then add the remaining sweet cherries and chocolate chunks.
½ cup cherry preserves
Bake for roughly 55-75 minutes, testing for doneness by inserting a toothpick into the center of the brownies beginning at 55 minutes. You’ll know they’re done when the edges are set, but a toothpick comes out with a few moist crumbs on the toothpick. Set aside to cool for about 45 minutes to an hour on a cooling rack.
After the brownies have cooled, cut them into pieces, and enjoy! These work well as anywhere from 9-16 pieces! Serve with a scoop of vanilla or cherry Garcia ice cream if desired!
Store leftovers in an airtight container at room temperature for up to 4-5 days for the freshest-tasting brownies. Truthfully, they will last a bit longer than that but they may begin to lose some of their potent flavor. To freeze, wrap tightly in plastic wrap, then aluminum foil, and place in the freezer for up to 3 months.
