Layering: Begin by layering the ingredients in your crockpot. Start with the peanuts, followed by the chocolate chips, almond bark, and white chocolate chips.

Cooking: Set your crockpot to low heat and let the ingredients melt for 1 to 2 hours. Make sure to stir every 20 minutes to ensure even melting and to prevent any ingredient from burning.

Mixing: Once everything is melted, add the crushed pretzels and give it a good stir, ensuring everything is well combined.

Setting: Using a spoon, drop dollops of the mixture onto parchment paper or silicone baking mats. While still wet, sprinkle the holiday M&Ms on top.

Cooling: Allow the Christmas Crack to cool for several hours. Once set, they can be stored in an airtight container.
