Recipe: Blueberry Mug Muffin

Breakfast Recipes, Pre + Post Workout Recipes, Snack and Appetizer Recipes


I’ve always loved muffins but most are loaded with sugar and white flour. This healthy muffin in a mug recipe is quick, easy, very low carb and high in fiber. Oh and the best part?! You make it in a coffee mug! Which means there’s only one easy dish to throw in the dishwasher.

Oh, and the second-best part?! It only takes one minute to cook! So yes, a muffin in a minute in a mug. And it’s healthy – so really there are three best parts! 😉 How’s that for a good morning?

This mug muffin is delicious for breakfast, a snack or even dessert. Plus it’s gluten-free, dairy-free, and keto-friendly! While a small amount of blueberries are okay on the keto diet, you can always skip them and just use nuts and seeds for add-ins to keep it even lower in carbs.

What To Put in a Mug Muffin

Once you have your base – which includes flaxseed meal, baking soda and an egg in this case – it’s easy to change things up according to your liking.

Our favorite way to serve this mug muffin is with a good handful of blueberries and walnuts. It’s the perfect slightly sweet muffin with just a bit of crunch.

Looking for a savory variation? 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

If you’re new to the idea of a muffin in a mug, have no fear! It’s just as easy as it sounds. Simply mix your ingredients in a mug, microwave and voila, a delicious, healthy muffin!

And 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).

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 become gelatinous.

Because this 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.

Thanks for posting this!! I got this off of a Chris Freytag post years ago, and had the recipe taped inside my cupboard door. We moved, I lost it, so glad to start eating these again!

Hey guys. Well I made three times the mix in a silicon muffin tray, came out good, cooked a bit longer, but I found them a bit heavy, def not sweet. So next I made a mug one, Half flaxseed and half coconut flour,, lemon zest, blueberry and a few flaked almonds,, yummo. Very filling. Will try the savoury one next!!

The confusion of the woman who thought it was a TBL spoon was that the tsp was in capital letters in the video which is generally not in caps in reference to a recipe. I have to always laugh when people change the recipe. I made it and love it as is! Especially since i am trying to get the sugar out of my diet! Thanks

Chris, how could I incorporate coconut flour into this recipe? tx.

    Hi there! I've never used coconut flour in this recipe so I'm not sure how it would work. Let me know if you try it!

Actually, I did choke. It was pretty scary. I don't eat fruit (diabetic severely sensitive to carbs) so I'm not going to be making this again, but it tasted pretty good. A little spongy and eggy for me.
