For the mini brownie muffins, I just used a brownie mix prepared like normal and cooked in a mini muffin pan.

Once your Mini Brownie Muffins are prepared, melt the yellow candy melts.

Before covering the marshmallow in the yellow candy melts, place a little dot on the wax paper. This is where you will put the marshmallow after it has been covered; it helps keep the bottom of the marshmallow covered while drying.

Place a toothpick or something similar on top of the marshmallow and cover completely.

Once the yellow coating has dried completely, place it on top of your mini muffin brownie.

Use the blue cookie frosting to draw a blue line all the way around the minions; this will help connect the marshmallow and the brownie. Allow to dry. Place a dab of black writing gel on the back of the candy as the eyes. Using the black writing gel, draw a line around the smartie, around the marshmallow, and place a dab in the middle of the smartie so it looks like an eye.
