Coffee (Mug) Cake

In a small bowl, stir together all the ingredients for the main batter (1/4 cup oat flour, 1 tbsp cashew butter, 2 tbsp oat milk, 2 tbsp maple syrup, 1 tbsp ground flax, 1/4 tsp baking soda, and a pinch of salt). Pour the batter into a greased ramekin or mug. In the same (dirty) bowl, combine the remaining ingredients for the crumble topping (1 tbsp oat flour, 1/2 tsp cashew butter, 1/2 tsp coconut sugar, 1/8 tsp cinnamon, and pinches of cardamom and nutmeg totaling 1/8 tsp). If the crumble mixture seems really dry, add a splash of milk. Pour the crumble over the batter in the ramekin or mug. Cook in the microwave for 60-70 seconds. Top with an optional glaze, such as vanilla probiotic protein mixed with a little oat milk, or powdered sugar.
