Doughnut Milk Luge

From Nicole Iizuka, POPSUGAR Food

4 long doughnuts
1 cup semisweet chocolate chips
2 teaspoons coconut oil
Sprinkles
4 ounces milk

Cut a row out of the center of each doughnut and set aside.
Combine chocolate chips and coconut oil in a bowl and microwave for 30-second intervals until melted. Pour the melted chocolate through the doughnut, pouring off any excess. Let harden in the fridge, then add sprinkles to the chocolate.
Pour milk into 1-ounce shot glasses. When ready, hold the doughnut up to your mouth and pour milk down the center!
