Chocolate Frosting Rim

1. Blend butter until light and fluffy.
2. With the mixer on low, sift in the powdered sugar and cocoa powder. Add the heavy cream. Continue to mix on medium-high for about two more minutes, until combined.
3. Use an offset spatula or knife to carefully spread the chocolate frosting along the outside rim of each glass.
4. Pour sprinkles on a small plate and carefully roll each frosting covered rim in sprinkles, ensuring that they fully cover the frosting.
5. Chill glasses in freezer.

Whipped Cream

1. Combine heavy cream and sugar in a medium sized bowl. Mix on medium-high with a handheld or stand mixer until somewhat stiff peaks have formed. Cover and refrigerate until ready to use, slightly whisking before using if need be.

Chocolate Irish Cream Milkshakes

1. Puree ice cream, milk, and Irish Cream in a blender until thick and creamy. I recommend adding 1 tbsp of Irish Cream, tasting it, and adding up to another tbsp if you want it to be stronger.

Assembly

1. Pour milkshake into each glass, being careful not to let any drip on the sprinkle covered rim.
2. Top each milkshake with a spoonful of whipped cream and more sprinkles.
3. Enjoy!
