Ingredients

Base:

  • 3 tbsp oat flour
  • ½ tsp baking powder
  • ½ tsp cinnamon
  • 1 pinch salt
  • 1 tbsp Greek yogurt
  • 1 egg white
  • 1 tbsp milk almond, oat, or dairy
  • ½ tsp vanilla extract
  • 1 tsp maple syrup or sweetener of choice

Cinnamon swirl:

  • ½ tsp cinnamon
  • ¼ tsp butter melted, or coconut oil
  • ½ tsp maple syrup

Optional glaze:

  • 1 tbsp Greek yogurt
  • ¼ tsp vanilla extract

Equipment

  • Microwave-safe mug
  • Small mixing bowl

Instructions

  • Mix all base ingredients in a mug until smooth.
    3 tbsp oat flour, ½ tsp baking powder, ½ tsp cinnamon, 1 pinch salt, 1 tbsp Greek yogurt, 1 egg white, 1 tbsp milk, ½ tsp vanilla extract, 1 tsp maple syrup
  • In a small bowl, combine swirl ingredients. Drop the swirl into the batter and use a toothpick or knife to create a marbled pattern.
    ½ tsp cinnamon, ¼ tsp butter, ½ tsp maple syrup
  • Microwave 60–75 seconds, or until just set but still soft in the centre.
  • Stir together the glaze and drizzle over top while warm.
    1 tbsp Greek yogurt, ¼ tsp vanilla extract

Cooking Tips

  • Don’t Overcook: Microwave in short bursts—start with 60 seconds. Overcooking makes it rubbery.
  • Use a Tall Mug: Choose an 8–10 oz mug to prevent overflow as the cake rises.
  • Gluten-Free Reminder: Only certified gluten-free oat flour is safe for gluten sensitivity.
  • Make it Dairy-Free: Swap Greek yogurt for coconut yogurt and use almond or oat milk.
  • Sweetener Swaps: Use stevia, monk fruit, or erythritol to make it added-sugar free.
  • Flavour Boosters: Add a pinch of cardamom, orange zest, or chopped nuts (if not allergen-restricted).
  • Texture Tip: Let it cool for 1–2 minutes after microwaving to finish setting before glazing.
