One-Bowl Mocha Brownies

These one-bowl mocha brownies, made with dark chocolate, cocoa, flour, sugar, and butter, get their kick from instant coffee. Best of all, as the name suggests, it’s all made in one bowl.

I we’re going to spend the time and money and calories to make brownies, we’re going to really splurge and make gooey, fudgy, soul-satiatingly messy brownies. And sometimes, we like to take it one step further and make the brownies even more worthwhile and memorable, even, by making them mocha. So worth it.

  • 2 ounces semisweet or dark chocolate chips or chopped chocolate
  • 1 stick unsalted butter (4 oz), plus more for the baking dish
  • 2 cups semisweet or dark chocolate chips or chopped chocolate (12 oz)
  • 1 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1/2 cup all-purpose flour
  • 2 tablespoons cocoa powder
  • 1/2 teaspoon salt
  • 2 large eggs
  • 1 tablespoon instant coffee or, for a more robust taste, espresso granules


  • 1. Preheat the oven to 350°F (176ºC). Butter an 8-by-8-inch glass baking dish.
  • 2. In a large microwavable bowl, combine the chopped semisweet chocolate, butter, and 1 cup chocolate chips or chopped chocolate. Microwave on high for 1 1/2 minutes. Whisk together the melted butter and chocolate.
  • 3. Whisk in the sugar, vanilla, flour, cocoa powder, and salt. Let cool for a minute or so and then whisk in the eggs and instant coffee or espresso granules. Whisk until the batter is smooth, about 1 minute. Fold in the remaining 1 cup chocolate chips or chopped chocolate. Scrape the batter into the baking dish.
  • 4. Bake the brownies for 22 to 25 minutes. You can try to check the brownies for doneness by inserting a tester or toothpick in the center. (Although since there are chunks of chocolate in the brownies, you can’t really be certain with the toothpick method as the toothpick may come out covered with gooey chocolate so check the brownies for doneness in several place. You may need to guess a little and leave them in the oven a touch longer if you like them less gooey.) Let the brownies cool slightly in the pan on a wire rack before cutting and serving.
