This moist, gluten-free, protein mug cake does not use any protein powder or baking powder to achieve a fluffy, moist, and decadent texture.

Thanks to the additions of egg and PbFit powder, this recipe contains 18g of natural protein.

While I do like to experiment with protein powder in baking, it's always possible to meet your protein goals without protein supplements.

This recipe is also gluten-free, does not include baking powder, and is made in under 2 minutes.

Protein mug cakes along with protein bars are an easy way to get in additional protein throughout my day.

Taste and Texture:

Besides the fact that this recipe is quick and easy to make, the taste and texture is unbeatable.

Moist and Spongy:

Thanks to the mashed banana and egg, this mug cake turns out wonderfully moist and spongy.

It has a tender crumb that melts in your mouth, offering a satisfying cake-like texture.

Nutty and Rich:

The addition of pb fit (peanut butter powder) bring a nutty richness to the cake that complements the banana very well.

Balanced Sweetness:

The natural sugars in the mashed banana provide just the right amount of sweetness, without the need for added sugars.

It's a treat that's pleasantly sweet without being overly sugary.

Fluffy and Light:

Unlike some other gluten-free desserts, this mug cake doesn't come out overly dense.

It retains a pleasing lightness and fluffiness, making it a satisfying yet not overly heavy dessert option.

Microwaving Time and Instructions

Microwaving the mug cake is a key step in ensuring a delightful texture and taste. Here are the recommended microwaving instructions to follow:

Cooking in Short Intervals:

When microwaving, it's crucial to use short intervals, typically around 30 seconds each. This approach helps prevent overcooking and ensures the cake turns out just right.

Microwave Time Variability:

I ended up cooking my mug cake for 2 minutes in 30 second intervals.

Keep in mind that the exact microwaving time can vary depending on the wattage of your microwave oven. As a general guideline, start with 30 seconds and then check the cake's progress.

Visual Check:

After each 30-second interval, visually inspect the cake. It should rise and set, with the center no longer appearing wet.

To test doneness, insert a toothpick or cake tester into the center. If it comes out mostly clean with a few moist crumbs, the cake is ready. If it's still gooey in the middle, it needs a bit more time.

Mug Type Matters:

It's worth noting that the type of mug you use can impact microwaving times.

Microwave-safe mugs with thinner walls might require less time than thicker ceramic mugs.

Be mindful of the mug's material and adjust the microwaving time accordingly.

Power Levels:

If your microwave allows you to adjust power levels, consider using 50-70% power for a more even and gentle cooking process.

This can help ensure that the cake cooks evenly without risking dry edges or an undercooked center.

Resting Time:

Once the cake reaches your desired texture and doneness, carefully remove the mug from the microwave (remember, it will be hot) and let the cake rest for a minute or two.

During this brief resting period, the residual heat will continue to set the cake.

Variations and Customizations:

This recipe is a blank canvas and can be easily customized to additional toppings and flavors. Here are some of my favorite additions.

Chocolate:

Fold in some chocolate chips or chunks into the batter. This addition will create pockets of gooey, chocolatey goodness that pairs so well with the nutty peanut butter flavor and banana.

Nutty Crunch:

For an extra layer of texture and flavor, chop up your favorite nuts—such as almonds, pecans, or walnuts—and sprinkle them into the batter.

Spice It Up:

Add a pinch of your favorite spices, such as cinnamon, nutmeg, or even a dash of espresso powder. These spices can provide a delightful depth of flavor.

Drizzles and Toppings:

After microwaving, top your mug cake with a drizzle of honey, a dollop of Greek yogurt, or some natural peanut butter.

Tips for A Perfect Mug Cake

How to make sure your mug cake comes out perfect every time.

Thorough Mixing:

Begin by ensuring that you thoroughly mix the ingredients.

The mashed banana, coconut flour, egg, and pb fit should be well combined to create a smooth, consistent batter. This ensures even cooking and a uniform texture.

Use a Microwave-Safe Mug:

Always use a microwave-safe mug or container to prepare your mug cake.

It's not only essential for safety but also helps in even cooking.

Adjust for Your Microwave:

Keep in mind that microwave cooking times can vary based on the wattage of your microwave oven.

If you know your microwave's wattage is significantly different from the average, consider adjusting the cooking time accordingly to prevent overcooking.

Prevent Spillage:

While not always necessary, placing a microwave-safe plate underneath the mug can help prevent spills in case the cake rises rapidly.

Don't Overcook:

Overcooking can result in a dry or rubbery texture.

Pay close attention during microwaving, and use the recommended short intervals to check for doneness.

The cake should be moist but not undercooked or overcooked.

Microwaving Time:

As mentioned earlier, microwave in short intervals, typically around 30 seconds, to have better control over the cooking process.

It's easier to add more time if needed than to salvage an overcooked cake.

Cooling Time:

Allow your mug cake to cool slightly before digging in. It continues to set during this time, ensuring a better texture and making it easier to handle.

Enjoy Fresh:

Mug cakes are best enjoyed fresh out of the microwave when they are warm and at their peak of flavor and texture. They're perfect for a quick and satisfying dessert fix.

Ingredients

½ cup mashed banana about 1 medium banana
3 tablespoons coconut flour
1 egg
2 tablespoons PB Fit powdered peanut butter

Instructions

Crack the egg into a microwave-safe mug or bowl.
Beat the egg in the mug until it's well-mixed.
Add the mashed banana to the mug and stir it into the beaten egg until the mixture is smooth.
Incorporate the coconut flour and pb fit powderinto the mug, and continue stirring until there are no lumps, and the batter is well combined.
Microwave the mug on high for about 2-3 minutes, or until the cake has risen and set. Cooking times may vary depending on your microwave, so keep an eye on it to prevent overcooking.
Carefully remove the mug from the microwave (it will be hot), and let it cool for a minute or two.
You can enjoy the mug cake straight from the mug or remove it onto a plate. Optionally, top it with extra banana slices, a dollop of yogurt, a drizzle of honey, or a sprinkle of PB Fit for added flavor.

Notes

Mug Selection: Ensure you choose a microwave-safe mug or bowl that is large enough to accommodate the batter without overflowing during cooking.

Mashing Bananas: Use ripe bananas for a sweeter and smoother texture. Mash them thoroughly to eliminate lumps in the batter.

Coconut Flour: Coconut flour is highly absorbent. If your batter seems too thick, you can add a small amount of additional liquid, such as milk or water, to achieve your preferred consistency.

PB Fit or Peanut Butter: You can substitute PB Fit with regular peanut butter if desired. Adjust the quantity to taste, but keep in mind that peanut butter is denser than powdered peanut butter, so the texture may differ slightly.

Microwave Variations: Cooking times in the microwave can vary based on wattage and individual preferences. Start with 2 minutes and increase in 30-second intervals if necessary. Be cautious not to overcook, as this can result in a dry cake.

Toppings: Get creative with toppings! Besides the suggested garnishes, consider adding chocolate chips, chopped nuts, or a sprinkle of cinnamon for extra flavor and texture.

Sweetness: The recipe assumes that the ripe banana provides sufficient sweetness. If you prefer a sweeter cake, feel free to add a bit more honey or maple syrup.

Texture: This mug cake is intended to be moist and slightly dense, similar to traditional banana bread. If you prefer a lighter texture, you can add a pinch of baking powder, although it may affect the microwave cooking time.

Safety: When removing the mug from the microwave, handle it carefully as it will be hot. Allow it to cool for a short duration before enjoying.

Customization: Experiment with different flavor variations by adding extracts like vanilla or almond, or incorporating other fruits like blueberries or diced apples.
