Rinse the strawberries gently and pat each one completely dry with paper towels. Let them air-dry for a few minutes if needed. Make sure there is no moisture on the fruit, leaves, or stems, as water can cause melted chocolate to become thick and grainy.

Line a baking sheet with parchment paper. Separate your decorations into small bowls so the candy eyes, sprinkles, and chocolate chips are ready to use as soon as the strawberries are dipped.

Place the white chocolate in one heatproof bowl and the dark chocolate in another. Melt each separately over a saucepan of gently simmering water, stirring until smooth. Alternatively, microwave in 20-second intervals, stirring between each interval. If the chocolate is too thick for dipping, stir in a little coconut oil or shortening.

Hold each strawberry by its green leaves and dip it into the desired melted chocolate, turning gently to coat. Lift it out and let the excess chocolate drip back into the bowl. Place it on the prepared baking sheet and repeat, decorating one strawberry at a time while the coating is still wet.

For ghosts, dip strawberries in white chocolate and let a little extra chocolate pool at the bottom to create a ghostly shape. Add two candy eyes and a tiny chocolate mouth. For mummies, let the white coating set for a minute, then drizzle thin lines of white chocolate back and forth across the strawberry. Finish with two candy eyes.

For pumpkins, coat strawberries in orange-tinted chocolate or orange sanding sugar, then pipe thin vertical lines and add a small chocolate face. For monsters, use green-colored candy melts or green sanding sugar and attach candy eyes. For a simpler option, coat strawberries in dark or white chocolate and immediately add Halloween sprinkles.

Allow the decorated strawberries to rest on the parchment-lined tray until the coating is firm, about 15–20 minutes. If needed, refrigerate briefly to speed up setting. Serve once the chocolate has hardened for the best appearance and texture.
