1. Preheat the oven to 180°F and line a cookie sheet with a silicone baking mat or parchment paper. This low temperature creates a gentle melting environment, preventing scorching.

2. Sprinkle both flavors of melting wafers onto the prepared pan. Mix the chips as you arrange them on the pan so they are equally dispersed. This ensures an even melt and makes swirling easier later on.

3. Place the pan with the wafers into the oven for 5 minutes, or until the chocolate is melted and glossy. Keep a close eye on it; melting wafers are designed to melt smoothly and quickly.

4. Using a silicone spatula or a butter knife, gently swirl the melted chocolates together. Drag the spatula side to side while moving down the pan, creating beautiful marbled patterns. Avoid over-swirling to keep distinct colors.

5. Immediately sprinkle the crushed Cadbury Mini Eggs evenly onto the top of the swirled, melted chocolate. Press them lightly into the chocolate to ensure they adhere as it sets.

6. Allow the chocolate to set completely. This can be done at room temperature (1-2 hours) or in the refrigerator (30-45 minutes). Ensure it’s fully firm before proceeding.

7. Once the chocolate is fully set, cut or break the bark into pieces. You can use a sharp knife for clean cuts or simply break it by hand for a rustic look. Serve and enjoy your homemade Easter treat!
