Line two baking sheets with parchment or wax paper, you will need room to lay all 24 cookies flat.

Melt the green candy melts in a microwave-safe bowl in 30 second bursts, stirring between each, until fully smooth and pourable.

Dip each cookie halfway into the melted candy, letting the excess drip back into the bowl for a clean edge.

Lay the dipped cookie flat on the parchment, green half up, and immediately press one red candy heart into the wet coating.

Repeat with the remaining cookies, rewarming the candy melts in 10 second bursts if they start to thicken.

Let the cookies sit at room temperature for 15 to 20 minutes, until the coating is firm and no longer tacky to the touch.
