Ingredients

Here’s what you’ll need to make your fluffy high-protein mug cake:

• 1 scoop vanilla or chocolate protein powder
• 1 tbsp almond flour (adds moisture + texture)
• 1/2 tsp baking powder
• 1 large egg
• 2 tbsp milk (almond, oat, or dairy)
• 1 tsp sweetener (monk fruit, erythritol, or sugar substitute)
• 1/2 tsp vanilla extract
• Pinch of salt
• Optional add-ins:
  • 1 tsp sugar-free chocolate chips
  • 1 tsp peanut butter
  • Fresh berries
  • Dash of cinnamon

Why These Ingredients Work

• Protein powder gives structure and the high-protein boost.
• Almond flour helps keep the cake moist and prevents dryness.
• Egg binds everything and gives lift.
• Baking powder ensures the cake rises and becomes fluffy.

Ingredient Notes

• Protein Powder: Whey works best for a soft, fluffy texture. Plant protein is fine but may require an extra tablespoon of milk.
• Sweetener: Adjust sweetness to taste. If your protein powder is already sweet, reduce the sweetener.
• Milk Choices: Any milk works — dairy gives the fluffiest result.
• Flour Swap: Coconut flour can be used, but only use ½ teaspoon because it absorbs more liquid.

Step-by-Step Instructions

Step 1: Combine the Dry Ingredients

In your mug (or mixing bowl), add the protein powder, almond flour, sweetener, baking powder, and salt. Stir until well combined.
You want a smooth, even mixture with no clumps.

Step 2: Add the Wet Ingredients

Crack in the egg, pour in the milk, and add the vanilla extract. Mix well until a creamy batter forms.
It should look slightly thick but smooth — similar to pancake batter.

Step 3: Add Optional Mix-Ins

This is the fun part! Add chocolate chips, a teaspoon of peanut butter, or berries for extra flavor. Fold gently into the batter.

Step 4: Microwave Until Fluffy

Microwave on high for 60–75 seconds.
The cake should rise, look fluffy, and feel slightly springy on top.
Avoid overcooking, or it may become dry — start with 60 seconds, then add 10 more if needed.

Step 5: Cool Slightly & Serve

Let the cake sit for 1 minute — it keeps cooking while resting.
Enjoy directly from the mug, or turn it out onto a plate for a more “cake-like” experience. 😋

Serving Suggestion

Take your mug cake to the next level with:

• A dollop of Greek yogurt
• A drizzle of sugar-free chocolate syrup
• Fresh berries on top
• A spoonful of nut butter
• Light dusting of cinnamon or cocoa powder

Perfect as a dessert, post-workout snack, or even breakfast!

Pro Tips & Variations

• Add Moisture: A teaspoon of Greek yogurt makes the cake extra moist and fluffy.
• Chocolate Version: Use chocolate protein powder + cocoa powder for a rich, brownie-like mug cake.
• Pumpkin Spice Twist: Add 1 tablespoon pumpkin puree + pumpkin spice for a fall-inspired treat.
• Low-Carb Upgrade: Use almond milk + low-carb sweetener to keep it keto-friendly.
• Storage Tip: Mug cakes are best fresh, but you can refrigerate leftovers for 24 hours. Reheat for 10–12 seconds.

Storage Information

Although mug cakes are meant to be enjoyed immediately, here’s how to store it if needed:

• Refrigerator: Store in an airtight container for up to 1 day.
• Freezer: Not recommended — texture becomes rubbery.
• Reheating: Microwave 10–15 seconds until warm, but don’t overheat.
