✨Ingredients substitutions and variations
- Banana - can be substituted with ¼ cup of applesauce.
- Maple syrup - Can be substituted with another liquid sweetener or sugar-free syrup to make this recipe low-sugar. If your protein powder is already quite sweet, reduce or skip it altogether.
- Peanut butter chocolate - mix in a tablespoon of peanut butter. Alternatively, substitute ½ the amount of protein powder with powdered peanut butter (like PB2).
- Jam-filled mug brownie - Before microwaving protein mug brownie, make a hole in the center, then add a dollop of your favorite jam.

✅ Helpful tips
- Use the right mug - A standard 8-oz mug or ramekin will work. Make sure the mug used is microwave-safe.
- Lightly grease the mug - This ensures that the mug brownie can be easily scooped out without leaving much behind. You can use a cooking spray to grease your mug.
- Do not overcook - An overcooked protein mug brownie will taste dry and chewy. I check mine by inserting a toothpick every 10-15 seconds after the initial 30 seconds of cooking.
- For extra gooey protein mug brownie - reduce cooking time to 45 seconds.
❔Commonly asked questions
If your mug brownie turns out tough and chewy, you have likely overcooked it. To fix it, try adding a splash of plant-based milk and topping it with something creamy like nut butter or fresh fruit to help soften the texture.
Also, double-check your measurements; using too much flour or dry ingredients can dry out the brownie. For best results, use the spoon and level method when measuring flour to avoid packing in too much.
Mug brownie can be cooked in the oven instead of the microwave. Preheat your oven to 180°C (350°F) and bake for 10-15 minutes, or until the center is just set. Make sure your mug or ramekin is oven-safe to avoid any cracking.
It is safe to microwave protein powder. While heating may slightly change the structure of the protein (called denaturation), it doesn't affect the nutrient content. Hence, your brownie will still be protein-packed and delicious.

Absolutely delicious! I used chocolate protein powder, so I omitted the cocoa powder, and I opted for regular flour instead of oat flour since I didn't have any at hand, and the recipe still turned out great! It was moist and spongy, and had a chocolate banana bread taste. 10/10 will make again!
