Key Ingredients
The chocolate mug cake is moist, gooey, and packed with 27 grams per serving, depending on your protein powder. Here’s what you need to get started.
- Coconut Oil: Prepare the mug or ramekin with melted coconut oil to prevent the cake from sticking.
- Egg: Eggs provide structure and bind the ingredients together.
- Milk: Include milk or water in the batter since almond flour absorbs differently than all-purpose flour and other flour. Experiment with regular milk, almond milk, oat milk, soy milk, or coconut milk to find what you like.
- Almond Flour: Use blanched almond flour, made from almonds with the skins removed, for the best results. I prefer blanched almond flour for baking because it produces a lighter batter, making the mug cake less dense.
- Protein Powder: Flavor the mug cake with your favorite chocolate protein powder. The best type of protein powder depends on your budget, diet, and personal preferences, but here are a few suggestions. I use chocolate Truvani protein powder, whereas my husband makes his with chocolate Optimum Nutrition protein powder.
- Cocoa Powder: Add color and decadent flavor with Dutch-process cocoa powder.
- Monk Fruit: Sweeten the high-protein snack with a sugar-free option like monk fruit or replace it with bananas, honey, agave syrup, maple syrup, or light brown sugar.
- Baking Powder: Baking powder lifts the batter, giving the cake a fluffy texture.
- Chocolate Chips: Mix dark chocolate chips into the batter and use them as a topping.
Additions and Substitutions
Customize your chocolate mug cake with protein powder and other mix-ins. The flavor of the protein powder you use changes the taste of the cake, so feel free to experiment and find a flavor and brand you love.
How to Make Protein Mug Cake
The full recipe with measurements is in the recipe card below.
Step 1: Warm the coconut oil in a mug or ramekin until melted (but not boiling) for 20-30 seconds, depending on the strength of your microwave.

Step 2: Add the egg and almond milk and stir to combine.

Step 3: Then, mix in the remaining ingredients until smooth and free of clumps.

Step 4: Top the cake with a few more chocolate chips and microwave for 60-80 seconds.

Expert Tips
- Give the cake extra room. Use a large microwave-safe mug or divide the batter into two ramekins since the batter will expand in the microwave.
- Microwave in increments. I recommend cooking the cake a little at a time to understand how your microwave cooks. I usually microwave 60-80-second seconds at a time until the cake is cooked.
- Test the cake. Insert a toothpick or a fork into the mug cake. If it comes out clean, the cake is ready.
