These easy gluten-free chocolate cake mix cookies require just three simple ingredients and are ready in minutes, making them perfect for busy parents, last-minute gatherings, or spontaneous sweet cravings.
Preheat the oven to 350°F (175°C). Line a baking tray with parchment paper.
In a medium bowl, combine the gluten-free cake mix, melted butter (or vegetable oil), and egg. Stir until a thick, dough-like consistency forms. If adding mix-ins, gently fold them in now.
Scoop tablespoon-sized portions of dough onto the prepared baking tray, spacing them about 2 inches apart.
Bake in the preheated oven for 8-10 minutes, or until edges are slightly golden. Be careful not to over-bake; cookies should remain soft in the center.
Allow cookies to cool on the baking tray for 5 minutes, then transfer them to a wire rack to cool completely.
