1-First, preheat the oven to 400°F (200°C). Cut out 9 small circles of parchment paper and line the bottom of a muffin pan, then spray the pan with cooking spray. This sets the stage for easy removal and prevents sticking.

2-Next, in a small bowl, whisk together the flour, cocoa powder, baking powder, and salt. This dry mix is the foundation of your batter, ensuring a light and airy result.

3-Then, in a mixing bowl with a whisk attachment, beat the eggs, sugar, and vanilla extract on medium-high speed for about 5 minutes, or until the mixture is thick, white, and has tripled in size. This step is crucial for that fluffy texture we all love.

4-After that, melt the chocolate and butter in a heatproof bowl set over simmering water until smooth. Let it cool slightly, then gently fold it into the egg mixture to keep the air in the batter.

5-Now, add the flour mixture and fold gently until combined, preserving as much air in the batter as possible. Divide the batter evenly into the 9 muffin cups, filling each about halfway, and place one frozen mini caramel egg in the center of each cup.

6-Finally, bake for 7 to 8 minutes. Transfer the pan to a wire rack and let it rest for 1 to 2 minutes, then place a cookie sheet on top and flip the pan. Use a spatula to transfer the mini cakes to a serving plate, dust with powdered sugar, and serve immediately with fresh berries or vanilla ice cream if desired. For dietary adaptations, use substitutes like flaxseed for eggs, and adjust baking time if needed.
