Microwave Method: 

  1. Add the lemon juice, cashew butter, maple syrup, non dairy yogurt, vanilla and lemon zest into a mug and stir until combined. 
  2. Add in the oat flour and baking powder and mix until just combined. If the batter looks too thick (due to thicker yogurts), stir in 1 tbsp of non dairy milk. Fold in blueberries. 
  3. Microwave on high (1000 W) for 1 minute and 30 seconds. Microwave for another 10 seconds if needed.
  4. Let it cool for 2 minutes and enjoy!

Oven Method:

  1. Follow steps 1 & 2 above.
  2. Bake at 350 F for 10-12 minutes until cake rises and top is cooked. Check doneness by inserting toothpick and ensuring it comes out mostly clean.
