Ingredients You Need (Only 3 Things)

This cake is made with three ingredients. But even with three, the final test and texture will depend on what exactly you will use.  Let me explain every ingredient:

1. Protein Powder – 1 scoop (about 25–30g):

A good protein powder is going to be your cake’s base. It will give you flavor, texture, and, of course, protein content for which we are making this cake. 

You can use whey protein of any flavor, like vanilla, chocolate, or peanut butter. They all are good. 

And if you are vegan, you can even go with the plant-based protein. 

But keep in mind that vegan proteins have a slightly different texture, which you will get in your cake as well.

If you’re using Whey Protein: You will get a soft and fluffy cake. 

If using Plant Based: Your cake might be a little denser, so you’ll need to add more milk.

Some good options:

• Vanilla Whey: For a classic base flavor (I currently have from Optimum Nutrition)
• Chocolate Plant-Based: Makes it more brownie-like (Try Orgain or Vega)

2. Mashed Banana or Applesauce – 2 tbsp (about 30g):

This is going to be the replacement of your eggs. It will also add natural sweetness and softness to your cake. You can try any of them:

• Mashed banana: It is more sweet and has a stronger flavor
• Unsweetened applesauce: It is milder and lets protein powder flavor stand out

However, if you want your cake to be more like a dessert, then you should use a banana. 

But if you want a natural one, I would recommend you use applesauce.

3. Milk – 2 to 3 tbsp (adjust as needed):

You can use any type of milk, like regular dairy, almond milk, soya milk, or oat milk; they are all fine.

For this cream 3 Ingredient protein powder mug cake without egg, I specifically used oat milk because it is creamy and has a little natural sweetness.

By the way, you will have to add just enough to make your cake smooth and give it a better texture, but it shouldn’t be too dry or too runny.

How to Make 3 Ingredient Protein Mug Cake (Step-by-Step)

Here is my cooking process that I personally used when I made it last time. 

You just need a microwave-safe mug, medium or large size; you can choose any because this cake will also rise a little as it cooks.

Step 1: Mix the Ingredients

You want to take your mug or a separate small bowl and add the following ingredients:

• 1 scoop protein powder
• 2 tbsp mashed banana or applesauce
• 2 tbsp milk

Mix everything together until it forms a smooth batter. You don’t want lumps in that; it needs to be smooth.

If it’s too thick, add another spoonful of milk. And, If it is too thin, you should pinch more protein powder.

Optional tip: You can also add a pinch of baking powder (if you have one); it will make your cake a little more puffier — but it’s not necessary if you have to use it; otherwise, leave.

Step 2: Microwave:

Put that mug in the microwave and cook it on high power for 45 to 60 seconds.

You should start with 45 seconds. Later, check your cake center with a spoon; if you see it still looks too wet, then you need to keep it in the microwave for another 10–15 seconds.

Important: Don’t overcook it; otherwise, it will turn dry or rubbery, which isn’t quite good. The middle needs to be just set, soft, and a kind of sponge.

Step 3: Let It Sit (Optional but Recommended)

Once done, you want to wait for about 1 minute before digging in. It will help the texture settle and stop you from burning your mouth.

What to Do If Your Mug Cake Turns Dry or Gummy

This is one of the most common issues that many people face, and you might face too while making a protein mug cake.

Especially if you are using plant-based powders, but here is how you can avoid it and fix it.

• Add more liquid: You always want to check your cake batter. It should be pourable but thick. If it looks like dough, it’s too dry.
• Microwave less: you don’t want to cook for too long. Even if you cook 10 seconds extra, you will overcook the protein, which isn’t good. You should start with 45s and only go further if needed.
• Use mashed banana instead of applesauce: Bananas will keep your cake more moist because they contain more sugar and water.
• Add a spoonful of yogurt or nut butter (optional tip): If you’re okay with more than 3 ingredients, you can add 1 tbsp of Greek yogurt or almond butter to make your cake richer and softer.

Even without adding anything else, if you just follow what I said, your mug cake won’t turn dry, and you will get the perfect cake.

How to Serve This Mug Cake for a Better Experience

If you want to turn this 3-ingredient protein mug cake recipe into a mini dessert. Here are some quick topping ideas I recommend to you without putting a lot of effort:

• Drizzle a little peanut butter or almond butter on top; it will add creaminess and healthy fat.
• Top with a spoon of Greek yogurt or coconut yogurt: It will add contrast and make it feel like frosting.
• Sprinkle cocoa powder or cinnamon: Good if you want to make your cake aromatic.
• Add chocolate chips or crushed nuts: You should add them right after microwaving so that they can melt a bit.
• Top with berries or banana slices: especially when you’re making it for a post-workout treat or breakfast.

If you’re making this 3 ingredient protein powder mug cake with no egg recipe at night, you can also pair it with a warm cup of almond milk or protein coffee, and it tastes different.

 

Variations You Can Try Without Losing Simplicity

Even though this is a 3 ingredient protein-powder mug cake recipe, you can still swap it around to enhance it to match your needs.

Here are a few smart and simple swaps:

• Instead of mashed banana or applesauce: You can try mashed pumpkin or sweet potato puree, especially in the fall season.
• Use flavored milk: (like chocolate almond milk or vanilla soy milk) instead of plain. It will change the taste without adding new ingredients.
• Try half protein powder + half oat flour: this will help you reduce dryness, and add carbs if you want it for pre-workout. (If you’re on a weight loss goal, you can avoid that)
• Turn it into a layered dessert: Simply make this cake, then add a spoon of Greek yogurt, some cocoa powder, and another layer of the mug cake on top. It will be like a mini protein trifle.

Don’t forget to add a pinch of baking powder, especially if you want to have a puffy cake like the real one.

But even without it, this mug cake is pretty good. So it’s totally up to you. If You add baking powder or not.

When to Eat This Protein Powder Mug Cake

I believe that every time, it is good to eat this eggless, protein-rich mug cake. But based on how I use it and what people usually look for, here are some options.

Storage & Reheating Tips (If You Want to Make Ahead)

I recommend that you eat this cake right after making it. Because it tastes good when it is fresh and a little warm. 

But if you want to make 2 to 3 batches at once, here is what you should do.

• Refrigeration: You need to let it cool down, then cover your cake with cling wrap, or you can store it in a small airtight container. After that, you can keep it in the fridge for about 2 days.
• To reheat: Microwave for 15 to 20 seconds only. You want to warm it, not overcook it again.
• Pro Tip: You can add some milk on top before microwaving. This will keep your cake moist when reheating.

But again, I wanna say the best version is always the fresh one.

Frequently Asked Questions (FAQs)

Here are some questions and answers regarding 3-ingredient protein powder, much cared in mind, basically.

Can I use water instead of milk for this mug cake?

Yep, you can use water instead of milk, especially when you’re trying to cut down your calories and don’t want milk, as they’re often high in calorie content. 

But you want to keep that in mind. Milk, especially oats or almonds, will add creamy texture and flavors, which water can’t do. 

So the real recipe is with the milk, not with water. 

But if you want to do this experiment, you can do it. 

Your cake will feel slightly dry or plain, but again, you can add some mashed banana or nut butter to balance it.

Why did my mug cake turn rubbery?

The reason is that you would have overcooked it or used too little liquid. 

If you are using protein powder, especially whey, it will cook super fast and can become rubbery if you heat your cake even for an extra 10 seconds. 

That’s why you should keep checking it. 

I recommend starting with 45 seconds maximum, and after that, you can keep checking it. 

If it needs more heat, you can keep your cake in the microwave for 5 to 6 seconds or 10 seconds max and then check it again.

What’s the best protein powder to use for mug cakes?

Whey protein powder works pretty well; they are good for a soft, fluffy texture. And you can go with vanilla, chocolate, or even peanut butter flavor. 

They blend well. 

However, if you are vegan, you should go with non-whey protein. But you should be ready to add a little more milk since the whey protein is thicker and drier. 

Some brands that I recommend are Optimum Nutrition for whey and Orgain for plant-based protein.
