Melt almond bark in a microwave-safe container for 45 seconds. Stir, and heat an additional 10 seconds if needed. Be careful not to burn.
Once the chocolate coating is smooth, stir in oil and mint extract.
Lay a sheet of wax paper onto the counter.
One by one, dip Ritz crackers into the chocolate and coat both sides. Remove them with a fork, tapping the excess on the side of the container. Place on wax paper.
Before the chocolate dries, add sprinkles or nonpareils.
Let set completely and then remove from wax paper and store in an airtight container at room temperature or in the refrigerator.
