This might be the finest version of this concept I've created. They're delightful!.

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large bowl, combine the flour, cocoa powder, granulated sugar, brown sugar, baking powder, and salt.
In a separate bowl, beat the eggs and vanilla extract together until well combined.
Add the ground beef to the egg mixture and mix until the beef is fully incorporated.
Gradually add the dry ingredients to the beef mixture, stirring until a thick dough forms.
Fold in the semi-sweet chocolate chips.
Using your hands, roll the dough into 1-inch balls and place them on the prepared baking sheet, leaving space between each ball.
Bake in the preheated oven for 12-15 minutes, or until the bites are set and the tops are cracked.
Remove from the oven and let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Once cooled, dust with powdered sugar before serving.
Variations & Tips
For a spicier kick, add a pinch of cayenne pepper or chili powder to the dry ingredients. You can also experiment with different types of chocolate, such as dark or milk chocolate chips, to alter the sweetness level. For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend. If you prefer a more pronounced beef flavor, consider using a higher fat content ground beef, which will also add moisture to the bites.
