Eggless Protein Blueberry Muffins with Greek Yogurt

These eggless blueberry protein muffins are soft, fluffy and made with Greek yogurt and protein powder, with 14g of protein in each muffin. You do not need eggs, flax eggs or another specialist egg replacer-the Greek yogurt helps provide moisture and structure instead.

I first made these a couple of years ago when we went through that supermarket egg shortage. I remember there being literally no eggs for weeks but I really wanted to make muffins and I was disappointed with the quality of eggless blueberry muffins out there.

Since then, I've made large ones (like the ones you see in the single main images which are 14g protein each), medium ones (those you see in the multiples) and even little mini ones which I've given to a bunch of people.

They are filled with blueberries and finished with a subtle almond flavour that makes them taste more like a bakery muffin than the dry protein muffins you may have tried before (I'm quite proud of this fact!). Fresh or frozen blueberries work, so they are an easy breakfast meal prep to make throughout the year.

Ingredients

Sugar. You can swap the same amount for a coconut sugar or even a raw sugar. I wouldn't recommend a brown sugar as this will make them more dense (and they're already slightly dense). Wet substitutes like honey and maple syrup will change the texture too much and they'll end up too moist to rise.

All-purpose. Plain or all-purpose flour provides the main texture and I recommend weighing where possible as too much flour can make the muffins quite dry.

Salt. A small amount of salt balances the sweetness and brings out the blueberry, vanilla and almond flavours.

Baking powder. The muffins do not contain eggs, so baking powder is particularly important for helping them rise. Make sure yours is still fresh, as older baking powder can result in flatter, denser muffins.

Which protein powder works best in muffins?

I recommend using a plant-based protein powder because that is what this recipe was developed with. Plant protein absorbs liquid differently from whey and generally acts more like flour in this batter.

Vanilla protein powder adds sweetness and works well with the blueberries and almond extract. An unflavoured powder can also be used, although you may want to taste the batter mixture and adjust the flavouring before baking. Avoid strongly flavoured powders unless you know they work well with blueberries.

Protein powders vary between brands (I tested with True Protein's Vanilla Plant-Protein), so the batter may be slightly thicker or thinner than mine. It should be thick enough to scoop rather than pour, but there should be no dry pockets of flour. If it looks unusually dry after mixing, add milk one tablespoon at a time. If it is very loose, leave it for a few minutes before adding more flour because plant protein often continues absorbing liquid as it rests.

How do these blueberry muffins work without eggs?

Greek yogurt supplies moisture and helps the batter hold together, while the flour, plant protein powder and baking powder provide structure and lift. Unlike recipes using flax eggs or applesauce, these muffins do not need a separate egg replacement mixture. The finished texture may be slightly more substantial than a traditional egg-based muffin, but it should still be soft and fluffy when the batter is not overmixed or overbaked.

Substitutions and Variations

Mixed berries. Replace the blueberries with the same quantity of mixed berries. Smaller berries such as blueberries and raspberries work best because they distribute more evenly through the batter. If your frozen berry mix includes large strawberries, chop them into smaller pieces while still frozen before folding them through.

Dairy-free. Use a thick dairy-free Greek-style yogurt and your preferred unsweetened plant-based milk. Soy yogurt is generally the closest option for maintaining the protein content, while coconut yogurt may add a light coconut flavour and can vary considerably in thickness.

Different extract. Swap with vanilla for a classic blueberry muffin; swap with lemon for a more lemony flavour; swap with coconut for a more distinct flavour.

No added protein powder. You can substitute the same amount of protein powder with flour. But, they won't have the same reported protein content.

Fresh or frozen blueberries?

Both can work and I've done it both ways before - more often than not I'll use frozen blueberries as I always have a packet in my freezer ready to go. However, fresh are a lot easier to fold through without colouring the batter.

If using frozen, keep them frozen until the moment they are added. Thawed berries release extra moisture and are more likely to bleed through the batter.

Fold them through quickly and gently so they do not begin releasing juice into the batter.

For less colour bleeding, you can briefly rinse icy residue from frozen berries and dry them very thoroughly, although this is optional. The most important steps are keeping the berries cold and avoiding excessive mixing.

How to make Eggless Blueberry Protein Muffins

Step 1: In a large mixing bowl, whisk together the flour, protein powder, baking powder, salt, and sugar until well combined.

Step 2: Add milk, Greek yogurt and almond extract into the same bowl and mix until JUST combined. The mixture should be slightly more substantial than a typical muffin recipe but still move about freely. If it hasn't captured all the flour, add extra milk 1 tablespoon at a time (this can happen depending on the type of protein powder you use).

Recommended Equipment

Jumbo muffin pan. I use a six-cup jumbo muffin pan for this recipe, with each cavity holding approximately ½-¾ cup of batter. This is roughly double the amount used in a standard muffin, which is why each jumbo muffin contains approximately 14g of protein.

Tiny muffin pan. For a 24-cup smaller muffin pan, begin checking them after approximately 10 minutes at the lower oven temperature.

Standard muffin pan. For a standard 12-cup muffin pan, begin checking after approximately 12-15 minutes. This is actually the one I'll use most regularly (as you can see pictured below)

The muffins are ready when the tops spring back lightly and a skewer inserted into the centre comes out with a few moist crumbs rather than wet batter.

Using a smaller pan will produce more muffins, so the protein content per muffin will be lower than the stated 14g. The total protein across the full batch remains the same.

Meal Prepping Eggless Blueberry Protein Muffins

These eggless protein blueberry muffins are easy to prepare ahead for quick breakfasts and snacks.

For a more filling breakfast, pair a muffin with Greek yogurt, fruit or nut butter. The jumbo muffins provide approximately 14g of protein each, based on the recipe yield. Smaller muffins will contain less protein per muffin because the same batter is divided across more serves.

Storing

Allow them to cool completely before storing, as sealing warm muffins can trap steam and make the tops sticky.

Room Temperature. Up to two days in a cool environment at room temperature. Because the muffins contain Greek yogurt and fruit, refrigerate sooner in hot or humid conditions.

Fridge. Up to four or five days for best texture. I have left these in the fridge for 7 days and they do dry out a bit, but they are still fine after that time. They do firm up in the fridge though when slightly cold so I do recommend leaving them out at room temperature for about 15 minutes before eating.

Freezing blueberry muffins

If I know I won't get them before the week is up, I'll freeze some to have later. Wrapping them in some plastic wrap or aluminium foil (airtight) is the best way to keep them as fresh as possible. I also like to then pop them into a large ziplock bag to further decrease the likelihood that they'll get freezer burn.

They'll be at their best for 3 months, but 6 moths will still be fine to eat. They just tend to dry out the longer they're in the freezer so the quicker you eat them, the more you're going to enjoy them.

Defrosting and reheating

Defrost a muffin overnight in the fridge or leave it at room temperature until softened. For a quicker option, microwave it in short 15-20 second intervals until warmed through.

You can also slice the muffin in half and warm it in a toaster or air fryer for a slightly firmer edge. Avoid overheating, as protein muffins can dry out more quickly than traditional muffins.
