Bake your brownies & allow to cool to room temperature.
For the dough- beat butter & your sugars in mixer bowl until well combined.
Add in your flour, milk & vanilla. Beat until combined- don't over beat.
Fold in mini chocolate chips
Spread out in even layer over the top of your brownies.
Scatter your candy corn over the top & press in
Cover & refrigerate several hours before cutting.
Cut while cold & remove from pan. (I recommend close to bite size- not large pieces)
Allow to come close to room temperature before serving.
Store in air tight container for several days.
