Step 1: Prepare the Baking Sheet

1. Preheat Oven – Set your oven to 350°F (175°C).
2. Line the Pan – Cover a rimmed baking sheet with parchment paper or aluminum foil, then lightly grease it to prevent sticking.
3. Arrange the Crackers – Lay out the saltine crackers in a single layer, covering the entire pan.

Step 2: Make the Toffee

1. Melt the Butter and Sugar – In a medium saucepan over medium heat, melt the butter and brown sugar, stirring continuously.
2. Bring to a Boil – Once melted, bring to a boil and let it bubble for 3 minutes without stirring.
3. Add Vanilla – Remove from heat and stir in the vanilla extract.
4. Pour Over Crackers – Immediately pour the hot toffee mixture over the crackers, spreading it evenly.

Step 3: Bake the Base

1. Bake – Place the pan in the oven for 5 minutes. The toffee will bubble up—this is normal!
2. Remove from Oven – Once the toffee looks set, remove the pan from the oven and let it cool slightly.

Step 4: Add the Chocolate Layer

1. Melt the Chocolate – Sprinkle chocolate chips evenly over the hot toffee. Let sit for 2-3 minutes, then spread with a spatula until smooth.
2. Sprinkle Toppings – While the chocolate is still warm, scatter the chopped Cadbury Eggs, M&M’s, and other toppings over the surface.
3. Drizzle White Chocolate (Optional) – Melt white chocolate chips in the microwave in 15-second bursts, stirring in between. Drizzle over the top for a decorative finish.

Step 5: Cool and Crack

1. Let It Set – Allow the Cadbury Egg Crack to cool at room temperature for about 30 minutes, then transfer to the fridge for another 30 minutes until fully set.
2. Break into Pieces – Once firm, use your hands or a knife to break the candy into bite-sized pieces.
