Mug Muffin Ingredients

Use these simple but nutritious ingredients to make this healthy muffin recipe.

raw ingredients to make blueberry muffin in a mug recipe, labeled

Flaxseed Meal: instead of an all purpose flour base, this healthier muffin recipe is made with ground flaxseed. It not only gives this keto muffin structure, but also provides loads of fiber and heart healthy fats with very few carbs (just 1 net carb per muffin!).
Baking Powder: adds lift to make a fluffy muffin.
Stevia Powder: for a hint of sweetness. Omit the stevia if you are making a savory version.
Cinnamon: pairs well with the fruit in this muffin. Feel free to experiment with other spices like nutmeg, ginger, or pumpkin spice. You could also add some vanilla extract. If you are making a savory muffin, great options to use include fresh herbs like dill or chives OR dried italian seasoning.
Egg: gives this microwave mug muffin structure as well as filling protein.
Olive Oil: just a little bit of oil helps this muffin stay moist. You could also use coconut oil or melted butter instead.
Blueberries & Walnuts: we love making a blueberry muffin mug cake version of this recipe with fresh blueberries and walnuts but you can choose from a variety of different add-ins. Feel free to make this recipe your own!

Healthy Muffin in a Mug Variations

Add Nuts or Nut Butter: for crunch, add nuts to your muffin like walnuts, pecans, hazelnuts, pistachios, or peanuts. This muffin is also delicious when topped with some peanut butter or almond butter for serving.

Add Chocolate Chips: if you’re craving chocolate, add a few chocolate chips to your muffin batter before cooking in the microwave.

Make it Savory: Looking for a savory variation of this single serving muffin recipe? Substitute out the sweetener and cinnamon and add in shredded cheese, chopped veggies, and spices (dill is yummy) to pair alongside salads or soups.

How Make A Blueberry Mug Muffin

Follow these simple ingredients to make your new favorite healthy muffin.

If you’re new to the idea of a muffin in a mug, have no fear! It’s just as easy as it sounds.

Microwave: to make this microwave muffin, add all of your ingredients to a microwave-safe mug and stir well with a fork. Microwave on high for 1 minute or until the muffin has a fluffy and is cooked through. (Cooking time may vary slightly based on your microwave, but you shouldn’t need more than 1 1/2 minutes to cook.)

Oven: Although we prefer to make this muffin in a microwave – it only takes 1 minute! – several of our readers have expressed interest in making it in the oven.

To make this muffin in the oven, preheat to 350 degrees and bake for 12-15 minutes. You can either choose to make it in an oven-proof mug (bake for a bit longer) or divided the mixture into two muffins in a muffin tin (bake for a bit shorter).

Serve: to serve this muffin in a mug, transfer the warm muffin to a plate or bowl and top with more juicy blueberries, plain Greek yogurt, and chopped nuts.

Vegan Substitute For Eggs

If you’d like to make this recipe vegan (or you’re simply out of eggs), you can substitute a few different things. When baking, a lot of people like to make a “flax egg.” To make a flax egg, simply mix 1 tablespoon ground flaxseed with 3 tablespoons of water and allow it to set until it becomes gelatinous.

Because this microwave mug cake recipe already uses flaxseed meal, we often like to use something else as an egg substitute. Try 1/2 of a banana, 1/4 cup of applesauce, or a 1/4 cup of dairy-free yogurt.
