Layer the peanuts and almond bark in a 5 quarter crock pot.
Cook on low for 1 hour.
Stir every 15-20 minutes to ensure that chocolate does not burn on the bottom of the crock pot.
Once all ingredients are melted, stir thoroughly to combine and stir in approximately 1/2 of the M&Ms.
Then use a spoon or a cookie scoop to scoop clusters onto a cookie sheet lined with wax paper or parchment paper. Then decorate each cluster with the sprinkles and leftover m&ms before they dry.
Put in the refrigerator or allow them to sit at room temperature until the chocolate has completely set (usually 1-2 hours).
Store the clusters in an airtight container or ziplock bag in the refrigerator. Enjoy!
Notes
We love this with white chocolate almond bark but this recipe would work great with chocolate almond bark as well!
