Cooking Tips
- Use a large mug: To prevent overflow during microwaving, choose a mug with at least 12–14 oz capacity.
- Let the batter rest: Allowing it to sit for 30–60 seconds helps the coconut flour absorb liquid for better texture.
- Watch the microwave time: Microwave power varies—start with 60 seconds, then check for doneness to avoid drying it out.
- Customize toppings: Try almond butter, low-sugar chocolate chips, or sliced strawberries as alternate toppings.
- Make it dairy-free: Use dairy-free yogurt and plant-based milk to make this mug cake fully dairy-free.
- Go sugar-free: Swap maple syrup for a sugar-free alternative like stevia or monk fruit for ultra low-carb diets.

FAQ
- Can I make this without a microwave?
Yes, bake it in a ramekin at 350°F (175°C) for 10–12 minutes until just set. - Can I replace coconut flour with almond flour?
Not directly—coconut flour absorbs much more liquid, so you'd need to adjust the ratios significantly. - Is this suitable for a keto diet?
It's very close—swap the maple syrup for a keto-friendly sweetener to make it fully keto. - Can I make this nut-free?
Yes, omit the peanut butter or use a seed butter like sunflower seed butter instead. - Can I prep this ahead of time?
You can mix the dry and wet ingredients separately and combine just before microwaving for a quick prep.
