Step 1: Wash strawberries gently and pat completely dry with paper towels. Any moisture will prevent chocolate from adhering properly.

Step 2: Line two baking sheets with parchment paper and set aside in a cool area of your kitchen.

Step 3: Melt dark chocolate chips with 1 tablespoon coconut oil in a microwave-safe bowl in 30-second intervals, stirring between each until smooth.

Step 4: Hold each strawberry by the stem and dip into melted chocolate, allowing excess to drip off before placing on prepared baking sheet.

Step 5: Refrigerate dipped strawberries for 15 minutes until chocolate sets completely.

Step 6: Melt white chocolate with remaining coconut oil using same microwave method until smooth and creamy.

Step 7: Transfer white chocolate to a piping bag or zip-lock bag with corner snipped off, then drizzle decoratively over set strawberries.

Step 8: Sprinkle with chopped pistachios or mini chocolate chips while white chocolate is still wet, then refrigerate for final 10 minutes.

Step 9: Dust lightly with powdered sugar just before serving for an elegant finishing touch.
