Creating 4th of July Brownie Bites is simple if you follow these easy steps:

1. Preheat your oven: Set your oven to 350°F (175°C). Grease a mini muffin pan or line it with paper liners for easier removal.
2. Melt the butter: In a microwave-safe bowl, melt the unsalted butter until completely liquid.
3. Mix sugar and butter: Add the granulated sugar to the melted butter and stir until well combined.
4. Add eggs and vanilla: Beat in the eggs one at a time, followed by the vanilla extract. Mix until fully incorporated.
5. Combine dry ingredients: In a separate bowl, sift together the all-purpose flour, cocoa powder, salt, and baking powder.
6. Combine wet and dry: Gradually add the dry mixture to the wet ingredients, stirring until just combined. Be careful not to overmix.
7. Fill the muffin pan: Spoon the brownie batter into the mini muffin pan, filling each cup about 3/4 full.
8. Bake: Place the pan in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
9. Cool the brownie bites: Remove from the oven and allow the brownie bites to cool in the pan for 10 minutes. Then, transfer them to a wire rack to cool completely.
10. Decorate: Once cooled, pipe red and blue frosting on top of each brownie bite. Finish with a sprinkle of star-shaped decorations for a festive touch.

Following these steps will ensure you create amazing 4th of July Brownie Bites that everyone will love!
