Heat milk to about 120 degrees in a pan or the microwave. You want it warm, but not hot.

Add yeast and sugar, and allow to sit for 5 minutes.

Once yeast has started to foam, add cake mix and flour.

Using your hands or the hook attachment on your Kitchen Aid mixer, knead dough until it forms a ball that no longer sticks to the sides of the bowl.

Generously spray a large bowl with non-stick cooking spray and place dough in bowl.

Cover with plastic wrap and let it double in size (about an hour) in a cool dark place.

Once it has doubled in size, punch it down.

On a lightly floured surface, roll out dough into a large rectangle, about an ½ inch thick.

Brush with melted butter and sprinkle with cocoa powder and M&M's® Hot Chocolate.

Tightly roll the the dough, starting with the long side and pinching the edges together at the end.

Cut rolls into 20-24 slices and place into 2 well greased baking pans.

Allow rolls to rise again in a cool dark place for about 30 minutes.

When rolls have once again doubled in size, bake at 400 degrees for 10-14 minutes.

Allow to cool while making the glaze.

To make the glaze combine melted butter, cocoa powder, milk, and powdered sugar, whisk until smooth.

Once rolls have cooled for about 5 minutes, pour glaze over rolls and garnish with extra M&M's®.
