In a bowl (or already in a mug), add 4 tbsp spelt flour, ½ tsp baking powder and ⅛ tsp vanilla and stir it. Add the wet ingredients: 2 tsp cashew butter, 6 tbsp plant based milk and 1 tsp agave syrup.
Break the white (vegan) chocolate into large pieces and fold into the dough together with the raspberries.
Transfer into a mug (or a small Microwave safe form) and put your it in your microwave for about 1 minute and 20 sec. at full power. Alternatively, you can also put your mug cake in the oven for 10-15 minutes at 180 degrees top/bottom heat.
If you want, top it with some more raspberries and cashew butter.
