Choosing ingredients: substitutions, types and benefits for lemon mug cake

Here’s a breakdown of the key ingredients and their substitutions for our fit lemon mug cake recipe:

Egg: Acting as the foundation of our mug cake, the egg provides essential protein. While there’s no direct vegan substitute, you can opt for just the egg white to cut down on calories.

Sweetener: Here’s where you have some flexibility. Feel free to get creative and use your preferred sweetener. We found success with xylitol, but erythritol is also a great option, especially if you’re watching your calorie intake.

Coconut Flour: This flour brings a unique texture and flavor to our mug cake. While it’s not easily replaced, it’s widely available in health food stores and often at a reasonable price. We haven’t found a suitable substitute in our tests, so it’s worth seeking out.

Oatmeal: A classic choice that adds substance and fiber to our recipe. If you don’t have oatmeal on hand, almond flour is a lower-calorie alternative that works well. For those who prefer a more traditional approach, wheat flour can be used, though it’s not as nutrient-dense.

Milk + Butter: This simple combination of milk and butter is key to achieving that light, airy texture we all love. Alternatively, you can swap in heavy cream for the same luxurious feel.

The beauty of this recipe is that it’s flexible—you can use any type of milk you prefer, whether it’s dairy, lactose-free, or plant-based.

When it comes to butter, coconut oil makes for a seamless replacement, ensuring your dough stays soft and moist. While olive oil can work, it may impart a subtle aftertaste.

Baking Powder: Ah, the secret ingredient for that perfect rise! Baking powder is the unsung hero of our fit microwave lime muffin, ensuring it reaches lofty heights with ease.

How to make lime mug cake in the microwave (step-by-step guide with images)

Step 1

In a bowl, add one egg and one and a half tablespoons of sweetener and mix well (we used xylitol, but you can use any sweetener you prefer). Beat until the yolk and egg white are fully combined (to avoid an eggy taste).

Step 2

Add two tablespoons of coconut flour and two tablespoons of oat flour and mix very well.

For a fluffy result, we don’t recommend substituting the coconut flour, but the oat flour can be replaced with most flours, like almond flour, wheat flour, oat bran, etc., using the same amount.

Step 3

Next, in another container, add one teaspoon of butter and microwave until melted, about 20 seconds. Add two tablespoons of your preferred milk (we used skim milk) to the butter and mix.

Step 4

Add the milk and butter mixture to the batter and mix.

Step 5

Add four tablespoons of lemon juice (we used the juice from one lemon) and mix.

Step 6

Add 2/3 teaspoon of baking powder and mix gently.

Step 7

This recipe makes two small dessert servings, which you can divide into two small containers before microwaving.

For a snack or breakfast, we recommend making both servings (the whole recipe). You can use a medium/large mug.

Microwave for 1 minute and 30 seconds on medium power or until a toothpick inserted comes out clean.

Step 8

Optional: If desired, finish with a lemon glaze and lemon zest. Below are some ideas you might like.

We keep dishing out cake recipes because, let’s face it, there’s never a bad time for cake! Not only are they scrumptious, but they’re also incredibly practical.

With our low carb lime mug cake recipe, you’ve got options for prepping ahead:

How to store lime mug cake in the fridge

Dough: Simply cover the container with plastic wrap or a lid and pop it in the fridge.

The dough can be stored like this for up to 24 hours. Just remember, if you’re using yeast, it’s best to add it when you’re ready to bake to ensure optimal rising.

Ready-Made Cake: Let your lime mug cake cool completely, then cover the container with plastic wrap or transfer it to an airtight container.

Pop it in the fridge, where it’ll stay fresh for up to 2-3 days. Just grab a slice whenever the craving strikes!

How to freeze this low carb lime mug cake

Dough: After preparing the dough, place it in an airtight container or freezer bag, ensuring to remove as much air as possible to prevent freezer burn.

Your dough can be safely stored in the freezer for up to 1 month. When you’re ready to use it, thaw it in the fridge overnight. Just remember to add the yeast right before microwaving to ensure that perfect rise.

Ready Cake: After your cake has fully cooled down, tightly wrap it first with plastic wrap and then with a layer of aluminum foil. Alternatively, you can place it in a freezer-safe airtight container. This double layering technique is essential for preventing freezer burn and ensuring the cake stays fresh.

Your ready-made cake can be stored in the freezer for up to 1 month. To enjoy, simply thaw it in the fridge overnight. If you prefer your cake warm, you can reheat it after thawing.

How to reheat sugar free lime mug cake

We have a soft spot for enjoying this low carb lemon mug cake straight out of the microwave or served cold. But hey, the beauty of this recipe is that you can also savor it warm if that’s more your vibe! Whether you prefer it chilled or with a cozy, comforting warmth, the choice is all yours.

Dough: If you’ve taken the dough out of the fridge, let it come to room temperature before adding the yeast. Then gently mix the yeast into the dough and follow the recipe instructions from where you left off.

Ready cake: To reheat a mug cake that has been refrigerated or defrosted, you can put it in the microwave for a few seconds until it is hot. The exact time will depend on the power of your microwave and the initial temperature of the cake.

Mistake to avoid and a tip for an amazing recipe

Before proceeding to the next ingredients, ensure you beat the egg thoroughly. This step is crucial, especially before incorporating the coconut flour, as it prevents any lingering egg taste from seeping into the recipe.

So, whip that egg until it’s smooth and well-combined before moving forward with the rest of the ingredients. Your taste buds will thank you!
