Creating Fudgy Chocolate Brownie Bites is simple when you follow these clear steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a mini muffin tin.
2. Melt Butter: In a medium saucepan, melt the unsalted butter over low heat. Remove from heat and let it cool slightly.
3. Mix Sugar and Eggs: In a large mixing bowl, combine the melted butter and granulated sugar. Stir until well mixed. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
4. Combine Dry Ingredients: In another bowl, whisk together the flour, cocoa powder, salt, and baking powder.
5. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
6. Add Chocolate Chips: If desired, fold in the semi-sweet chocolate chips for extra chocolatey goodness.
7. Fill Muffin Tin: Spoon the batter evenly into the prepared mini muffin tin, filling each cup about ¾ full.
8. Bake: Bake in the preheated oven for 20-25 minutes or until a toothpick inserted into the center comes out with a few moist crumbs.
9. Cool: Allow the brownie bites to cool in the tin for about 15 minutes before transferring them to a wire rack to cool completely.
10. Dust with Powdered Sugar: If desired, dust the cooled brownie bites with powdered sugar for a beautiful finish.

By following these steps, you’ll have a batch of fudgy brownie bites that are sure to impress!
