Preheat the oven to 350°F. Grease two cookie sheets.
Brownie Cookies
In a large bowl, whisk together flour, cocoa, baking powder, and salt. Set aside.
In a medium bowl, mix sugar, butter, honey, vanilla, and egg whites until combined. Add to the flour mixture. With your clean hands, mix dough just until blended.
With your lightly greased hands, using a 4 tablespoon cookie scoop, roll into balls and place on greased cookie sheets. Flatten each brownie cookie slightly with the back of a spoon or the back of a cup.
Bake just until brownies are slightly cracked, approximately 12 minutes. Cool cookies on a wire rack.
Ganache
In a heat-safe bowl, add in chocolate chips and set aside.
In a small pot, over low heat, heat heavy cream to a simmer but make sure not to let it boil.
Pour hot cream into the bowl over chocolate chips and cover the bowl with foil. Let sit for 3-5 minutes without stirring.
After 5 minutes, stir cream and chocolate chips together until melted and completely smooth.
Let ganache sit for at least 30 minutes.
Once cookies have completely cooled and ganache has set up a bit, spoon ganache onto the cookie and smooth it out.
Sprinkle with rainbow candy sprinkles and repeat until all cookies are decorated.
