Loaded with chocolate, these Fudgy Brownie Cookies have crisp edges and a soft, fudgy center—perfect for an afternoon snack, a sweet gift, or a chocolate lover’s treat.
Preheat the oven to 350 degrees Fahrenheit (177 degrees Celsius). Line baking sheets with parchment paper; set aside.
In a medium bowl, whisk together the flour, cornstarch, baking powder, and salt.
In a small bowl, whisk together the eggs, brown sugar, vanilla extract, and espresso powder.
Using a double boiler or a large bowl set over a pot of barely simmering water, stir the chopped chocolate and butter with a silicone spatula until melted and smooth. Remove from the heat and allow to cool until warm but not hot, about 5-10 minutes.
Add the egg mixture to the melted chocolate mixture; stir to combine. Gradually mix in the dry ingredients, then fold in the chocolate chips.
Using a standard-size cookie scoop, place the dough onto the prepared cookie sheets, leaving 2 inches between each ball of dough (they do spread a lot).
Place the cookie dough in the oven and bake for 10-12 minutes. The edges should be set, but the centers should be slightly gooey. Remove from the oven and allow to cool on the baking sheets for 3-4 minutes before transferring them to a wire rack to cool completely.
Notes
*Make sure your baking powder is fresh for the best results.**I like using Ghirardelli baking bars—they’re 4 oz. each.-You can also mix in chopped toasted nuts or swirl peanut butter into the batter!STORE the cookies in an airtight container at room temperature for 3-5 days to keep them soft and fudgy. For longer storage, FREEZE them in a single layer, then transfer them to a freezer-safe bag or container for up to 3 months.Let them thaw overnight and come to room temperature before serving. To enjoy them warm, microwave for 5-10 seconds.To make ahead, chill the dough before baking to prevent spreading. Refrigerate for 30 minutes to 24 hours for better texture and flavor.
