In a small saucepan, heat oat milk and whole turkey tail mushroom over low heat until the milk is warmed through, about 10 minutes.

Strain the mushrooms through a fine sieve, saving the oat milk and composting or discarding the mushrooms.

Return milk to the saucepan and turn heat again to low.

Slowly whisk in the chocolate mix until fully incorporated.

Pour into serving mugs and enjoy.
