01 - Preheat your oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the gluten-free flour, cocoa powder, baking soda, salt, and espresso powder until well blended.
03 - In a large bowl, beat the softened butter, melted coconut oil, brown sugar, and granulated sugar until light and creamy, about 2-3 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in the vanilla extract until fully incorporated.
05 - Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Do not overmix.
06 - Fold in the chocolate chips and crispy rice cereal until evenly distributed throughout the dough.
07 - Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.
08 - Bake for 11-13 minutes, or until the edges are set and the centers look slightly soft. The cookies will continue to firm up as they cool.
09 - Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
