Prepare your baking dish by lining it with parchment paper, allowing some overhang for easy removal later.
In a microwave-safe bowl, combine the semi-sweet chocolate chips and coconut oil. Heat in the microwave on medium power in 30-second intervals, stirring in between, until melted and smooth.
Once melted, add in the mini marshmallows and crushed graham crackers. Stir until everything is well combined.
Gently fold half of the colorful Easter candy into the mixture, reserving the other half for topping.
Pour the chocolate mixture into the prepared baking dish, spreading it evenly.
Sprinkle the reserved Easter candy on top, along with optional sprinkles for extra decoration.
Refrigerate the dish for at least 1 hour, or until set.
Once set, lift the parchment paper to remove the chocolate slab from the dish. Cut into 12 pieces.
