Preheat the oven to 350°F (175°C).
In a bowl, whisk together the flour, cocoa powder, baking powder, and salt.
In a separate bowl, cream the softened butter with granulated and brown sugars until light and fluffy.
Add the egg and vanilla extract, mixing until just incorporated.
Gradually mix in the dry ingredients until combined.
Scoop tablespoon-sized dough portions and roll into balls, then insert lollipop sticks.
Place the cookie pops on a baking sheet lined with parchment paper and bake for 10-12 minutes.
Allow the cookie pops to cool completely on a wire rack.
Melt the candy melts according to package instructions, then dip the cooled cookie pops halfway into the melted candy.
Decorate the cookie pops with edible eyes and sprinkles before the coating sets.
Let the decorated pops sit until the candy coating hardens.
