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.

FAQ
- Can I bake this in the oven instead of the microwave?
Yes, bake in an oven-safe ramekin at 350°F (175°C) for about 12–15 minutes. - Is this safe for people with diabetes?
Yes. It’s low in added sugar, high in protein and fibre, and made with whole food ingredients. - What’s a good sugar-free substitute for maple syrup?
Try stevia, monk fruit, or erythritol. Adjust to taste based on sweetness level. - Can I make this ahead of time?
It’s best fresh, but you can mix the dry ingredients in advance and store in a jar for quick prep later. - Can I make it egg-free?
Yes, use a flax egg (1 tbsp flaxseed + 3 tbsp water) or 2 tbsp unsweetened applesauce. - Is oat flour safe for gluten-free diets?
Yes, if it’s labeled certified gluten-free, since oats are often cross-contaminated during processing. - Can I double the recipe?
Not in one mug—it will overflow. Make two separate mugs instead.
