Ingredients You’ll Need
You probably have most of these at home already:
- 1 scoop chocolate protein powder (whey or plant-based)
- 1 tbsp almond flour (or coconut flour)
- 1 tbsp unsweetened cocoa powder
- 1/4 tsp baking powder
- Pinch of salt
- 1/4 tsp ground cinnamon (optional for that cozy twist)
- 1 egg (or flax egg for vegan option)
- 2 tbsp unsweetened almond milk (or any milk you like)
- 1 tbsp sugar-free maple syrup or honey
- 1 tbsp mini chocolate chips (optional, but highly recommended)
Step-by-Step: How to Make This Protein Mug Cake
Step 1: Mix the Dry Stuff
Grab a microwave-safe mug. Add protein powder, almond flour, cocoa powder, baking powder, salt, and cinnamon. Give it a quick stir.
Step 2: Add the Wet Ingredients
Crack in the egg. Pour in the almond milk and syrup. Stir until you have a smooth, thick batter. Don’t overmix, just enough to combine.
Step 3: Add Extras
Fold in those chocolate chips. They’ll melt into little pools of joy. You can also throw in chopped nuts or a spoon of peanut butter.
Step 4: Microwave Magic
Pop the mug in the microwave. Cook on high for 60–90 seconds. The center should be just set—not dry or rubbery.
Step 5: Let it Sit
Give it 30 seconds to rest. This helps the texture settle. Plus, no burnt tongues!
Make It Your Own
- Cinnamon Roll Vibes? Use vanilla protein powder, skip cocoa, and double the cinnamon.
- Berry Burst: Add fresh or frozen berries before microwaving.
- Peanut Butter Cup: Swirl in a teaspoon of natural peanut butter before microwaving.
- Vegan Option: Swap egg with flax egg and use a vegan protein powder.
You can play around with flavors and toppings based on what you’ve got lying around. That’s the beauty of easy mug cake recipes—they’re like a warm hug in a cup.

Tips for Trying This Out
- Don’t overcook it. Every microwave is different, so check at 60 seconds. You want it moist, not dry.
- Start small. New to mug recipes? Make one as a tester before serving to others.
- Cool before you dive in. It’ll continue cooking after microwaving. Letting it sit makes it even better.
- Use a big mug. The cake rises and could overflow if the mug’s too small.
- Protein type matters. Whey blends best, but plant-based works too—just adjust milk as needed.

Protein Mug Cake
Ingredients
Method
- Use a large microwave-safe mug. Add the dry ingredients: protein powder, almond flour, cocoa powder, baking powder, salt, and cinnamon. Stir well.
- Add in the egg, almond milk, and maple syrup. Mix until everything is combined and smooth.
- Stir in the chocolate chips or any extra add-ins like chopped nuts.
- Microwave on high for 60 to 90 seconds. The top should look set but still soft in the center.
- Let it sit for 30 seconds before digging in. It’ll firm up a bit more as it rests.
Notes
- Make sure your mug is large enough—this rises a lot in the microwave.
- You can use any milk you have, just avoid sweetened ones if you’re watching sugar.
- Don’t overcook it! It should be a little gooey in the middle.
- Vegan? Use a flax egg (1 tbsp ground flax + 2.5 tbsp water) instead of an egg.
Frequently Asked Questions
Can I use water instead of milk?
Yes, but the cake will be slightly less rich. Almond or oat milk gives a creamier texture.
What protein powder works best?
Whey isolate or a whey/casein blend. Plant-based powders can work too—just adjust the liquid.
Can I double the recipe?
Yep, just use a large mug or microwave-safe bowl. Cook 30 seconds longer.
Is this keto-friendly?
It can be! Use a keto-friendly protein powder, almond flour, and sugar-free syrup.
What’s the texture like?
Think light brownie meets sponge cake. It’s moist, slightly dense, and melt-in-your-mouth.
Can I make this ahead?
Not really. This one’s best hot and fresh. But you can pre-mix the dry ingredients in advance.
