Use an art brush dipped in piping gel to evenly coat 5 pink berries 3/4 of the way up, leaving 1/4 of the pink coating near the cap exposed. Place the white nonpareils in a cup and dip each berry into the sprinkles. Lightly tap the berry on the edge of the cup to release excess nonpareils. Let the berries stand on the parchment paper until set, about 15 minutes. Transfer each berry to a cupcake liner.
