🍫What you will need

- Maple syrup – Can be reduced or omitted if your protein powder is already sweet enough.
- Baking powder – Helps the batter rise, creating a fluffier, cake-like texture.

🔪How to make chocolate protein mug cake
Step 1: Add all dry ingredients to a ramekin or mug. Stir until well mixed.
Step 2: Add wet ingredients, mixing until a batter forms.
Step 3: Microwave for 60 seconds, then check for doneness. The middle should be mostly set.
Step 4: Allow to rest for a few minutes, then dig in and enjoy! Optionally, you can top it with toppings of choice before serving.
✔Helpful tips
- Use a microwave-safe mug – Ensure your mug is microwave-friendly to avoid any mishaps.
- Don’t overcook – Overcooking can make the cake dry and rubbery. Insert a toothpick down the middle and it should come out mostly clean with a few moist crumbs.
- Serve immediately – Best enjoyed fresh, but leftover chocolate protein mug cake can be stored in an airtight container and eaten within 1-2 days. I recommend enjoying leftovers cold as reheating might dry cake out and cause it to turn chewy.
❔Commonly asked questions
A rubbery protein mug cake is usually caused by overcooking or adding too much oil. Since this recipe does not use oil, the most likely culprit is overcooking.
To prevent this, check at the 60-second mark by inserting a toothpick into the center—if it comes out mostly clean with a few moist crumbs, your mug cake is ready!
You can bake this protein mug cake in the oven by preheating it to 180°C (350°F) and baking for 10-15 minutes. It will be slightly denser than the microwave version but still delicious!
If your protein mug cake turned out dry, it was likely overcooked. Since this recipe is lower in fat, even a little extra time in the microwave can make it dry out quickly. For a richer, more moist texture, try mixing in a tablespoon of peanut butter or your favorite nut butter!

It was great! The minute was enough for me, maybe even w little too much. But it was soooo much better than I expected. The chocolate chips sunk to the bottom and made this gooey sauce. Such a fast and tasty treat.
