Melt the butter in a pot, remove from the heat and stir in the white sugar.
Once that is combined, mix in your cocoa.
Add in your eggs and mix it very well.
Once it's all done, add in your flour and barely stir it in.
Unwrap and place the giant peanut butter cup right in the center of your seasoned skillet.
Pour the brownie batter around the chocolate bunny making sure not to get it on top. The 10 inch skillet will have extra batter left over.
You only want to fill the batter to about halfway up the side of the chocolate bunny, so the thicker the chocolate bunny the more batter you can use!
Place the M&M's just on top of the brownie batter, do not press in! They will sink in naturally.
Bake at 325 degrees for 30-35 minutes until the brownie batter is cooked.(you can test this using a thermometer, 165 degrees ensures the egg is cooked. Then you can safely have a chewy, under cooked brownie)
