How to Make a Blueberry Protein Mug Cake

A healthy, high-protein blueberry mug cake made with oat flour, yogurt, and fresh blueberries. Ready in 3 minutes fluffy, fruity, and energizing.

  • Total Time: 3 minutes
  • Yield: 1 mug cake

Ingredients

Scale

35 g (2 tbsp) nondairy yogurt

20 g (3 tbsp) oat flour

20 g (3 tbsp) vegan vanilla protein powder

½1 tbsp maple syrup (to taste)

⅓ tsp baking powder

65 ml (¼ cup) milk of choice

35 g (¼ cup) blueberries (fresh or frozen)

Instructions

1. In a small bowl, combine yogurt, oat flour, protein powder, maple syrup, and baking powder.

2. Add milk gradually and stir until smooth. Fold in blueberries gently.

3. Transfer the batter into a microwave-safe mug (12 oz).

4. Microwave on high for 1–2½ minutes, checking for doneness after 1 minute.

5. Let it cool for 1 minute before serving.

6. Top with Greek yogurt or nut butter and enjoy your blueberry protein mug cake warm.

Notes

Use certified gluten-free oat flour if needed.

Replace vegan protein powder with oat flour plus vanilla extract.

Avoid whey protein — it dries out in the microwave.

Microwave times vary; adjust in 10–15 second intervals.
