I am always looking for uses for frozen bananas because every time I have a banana that is too ripe to eat, I peel it, slice it and put it in the freezer for opportunities like this!
1/2 cup Irish cream (like Bailey's)
1/4 cup chocolate vodka - you can use regular vodka
1 pint coffee ice cream
1 banana, sliced and frozen
2 Tablespoons cocoa powder
Add all ingredients to a blender and blend on high until smooth.
Warning: This is very strong!!! You can add some milk and more ice cream if you think it's going to kick your butt after the first sip.
