Prep your tray: Line a baking sheet with parchment or a silicone mat. Clear some space in the fridge in case you want a quicker set.
Melt the chocolate: In a large microwave-safe bowl, combine chocolate chips, peanut butter, and butter or coconut oil. Microwave in 20–30 second bursts, stirring after each, until smooth and glossy.You can also melt gently over a double boiler.
Add flavor: Stir in vanilla and a pinch of salt. Taste a tiny bit. If it’s too sweet, add another pinch of salt.
Fold in the crunch: Add chow mein noodles (and coconut if using).Use a spatula to gently fold until everything is evenly coated. You’re looking for a generous coating on every strand without a pool of chocolate at the bottom.
Form the nests: Scoop heaping tablespoons onto the lined tray. Use the back of a spoon or your fingers to press a shallow well in the center of each mound to form a nest shape.
Decorate: While still soft, press 2–3 mini eggs or candies into the center.Add sprinkles if you like. Work quickly so the candy sticks before the chocolate sets.
Let them set: Leave at room temperature for 30–45 minutes, or chill in the fridge for 10–15 minutes until firm to the touch.
Serve: Once set, lift off the parchment and arrange on a platter. Keep a few extra candies nearby for refills and snacking.
