Greek Yogurt Banana Protein Muffins with Oats and Almond Butter
These greek yogurt banana protein muffins are the kind of breakfast that actually keeps you going until lunch. No mid-morning energy crash, no reaching for a snack bar at 10am. Just a genuinely satisfying, nutrient-dense muffin that happens to taste like something you would happily eat for dessert. Each muffin delivers around 12 grams of protein, thanks to a triple hit from plain Greek yogurt, vanilla protein powder, and almond butter. The ripe bananas bring natural sweetness, which means the added sweetener is kept to an absolute minimum.
The base uses a combination of rolled oats and oat flour rather than refined white flour. This swap does two things: it bumps up the fibre content significantly, and it gives the muffins a slightly denser, more satisfying crumb that holds together beautifully. Oats are also a brilliant source of beta-glucan, a soluble fibre that supports steady blood sugar levels, which is exactly what you want from a breakfast food. The almond butter weaves through the batter adding healthy monounsaturated fats, a gentle nuttiness, and extra creaminess that you would normally get from loads of oil or butter. Here we use just one tablespoon of melted coconut oil to keep the texture moist without piling on unnecessary calories.
Making these muffins is genuinely straightforward. You do not need a stand mixer or any fancy equipment. A couple of bowls, a fork, and a standard 12-hole muffin tin is all it takes. The bananas need to be properly ripe, with plenty of brown spots on the skin. Under-ripe bananas will not mash smoothly and the natural sugars will not be as developed, so the muffins will taste flat. If your bananas are not quite there yet, pop them unpeeled in a 160C oven for 15 minutes and they will soften and sweeten up perfectly. The Greek yogurt should be full-fat or at least 2 percent fat. Low-fat versions tend to make baked goods a little rubbery and do not contribute the same creamy richness. Full-fat Greek yogurt is also more satiating, so it actually works in your favour nutritionally.
Once baked, these muffins store brilliantly and are ideal for meal prep. Make a batch on Sunday and you have breakfast sorted for the whole week. They freeze exceptionally well too, so you can double the batch and keep a stash in the freezer for busy mornings. Pull one out the night before and let it thaw on the counter, or warm it in the microwave for about 40 seconds straight from frozen. A thin spread of almond butter or a drizzle of honey on top takes them from great to genuinely special. Kids love them too, and there is absolutely nothing in here that you would feel any hesitation about serving to them. Real ingredients, real nutrition, real flavour.
Ingredients
- 3 medium ripe bananas (heavily spotted skins give the best sweetness, about 300g peeled)
- 180 g plain full-fat Greek yogurt (around 3/4 cup, do not use fat-free)
- 2 large eggs (room temperature)
- 60 g smooth almond butter (about 3 tablespoons, natural with no added sugar)
- 1 tbsp coconut oil (melted and slightly cooled)
- 2 tbsp pure maple syrup (or raw honey)
- 1 tsp pure vanilla extract
- 100 g rolled oats (use certified gluten-free oats if needed, about 1 cup)
- 80 g oat flour (about 3/4 cup, or blend rolled oats until fine)
- 60 g vanilla whey protein powder (or plant-based vanilla protein, about 2 scoops, 20g protein per 30g serving)
- 1 tsp baking powder
- 1 tsp baking soda
- 1 tsp ground cinnamon
- 1 tsp fine sea salt
- 40 g dark chocolate chips (optional, 70 percent cocoa or higher, about 3 tablespoons)
Instructions
- 1
Preheat your oven to 180C (350F) fan-forced. Line a standard 12-hole muffin tin with paper liners or lightly grease each cavity with a little coconut oil.
Using paper liners makes cleanup far easier and helps the muffins release cleanly once cooled.
- 2
Peel the ripe bananas and place them in a large mixing bowl. Mash thoroughly with a fork until you get a smooth, lump-free puree. A few tiny lumps are fine, but aim for mostly smooth.
The riper the banana, the sweeter and more intensely flavoured your muffins will be. Blackened skins are actually ideal here.
- 3
Add the Greek yogurt, eggs, almond butter, melted coconut oil, maple syrup, and vanilla extract to the mashed banana. Whisk everything together with a fork or small balloon whisk until the mixture is uniform and slightly glossy.
Make sure your coconut oil is not too hot when it goes in or it may begin to scramble the eggs. Lukewarm is ideal.
- 4
In a separate medium bowl, combine the rolled oats, oat flour, protein powder, baking powder, baking soda, cinnamon, and sea salt. Stir with a fork to distribute everything evenly.
Sifting the protein powder and oat flour together prevents any lumps forming in the final batter.
- 5
Pour the dry ingredients into the wet ingredients and fold gently with a spatula until just combined. Stop as soon as you can no longer see dry flour. The batter will be thick and slightly sticky. If using chocolate chips, fold them in now.
Overmixing activates the gluten in oat flour and makes muffins dense and tough. A gentle hand here makes all the difference.
- 6
Let the batter rest for 5 minutes. This allows the oats to absorb some moisture and the baking powder to begin activating, which helps the muffins rise evenly.
- 7
Divide the batter evenly among the 12 muffin cavities, filling each about three-quarters full. Optionally, press a few extra chocolate chips on top of each muffin for a nicer finish.
An ice cream scoop or a large spoon makes portioning neat and quick.
- 8
Bake for 18 to 20 minutes, until the tops are set and lightly golden. A toothpick inserted into the centre of a muffin should come out clean or with just a few moist crumbs attached.
Protein powder can cause baked goods to brown a little faster than usual. If the tops are browning too quickly, loosely tent the tin with foil for the last 5 minutes.
- 9
Remove the tin from the oven and allow the muffins to cool in the tin for 5 minutes before transferring to a wire rack. They firm up as they cool, so do not rush this step.
Eating one warm is absolutely allowed. Just know they slice and hold together better once fully cooled.

Pro Tips
- ✓
Use bananas with very dark, spotted skins for maximum natural sweetness and the best muffin moisture.
- ✓
Do not substitute the Greek yogurt with regular yogurt. Greek yogurt is strained, so it is thicker and higher in protein, which directly affects texture and nutrition.
- ✓
If your protein powder is unflavoured, add an extra half teaspoon of vanilla extract and a teaspoon of extra maple syrup to compensate.
- ✓
Resting the batter for 5 minutes before baking makes a noticeable difference to the final rise and texture.
- ✓
For a nut-free version, swap the almond butter for sunflower seed butter in exactly the same quantity.
- ✓
Always measure oat flour by spooning it into the measuring cup and levelling off rather than scooping directly, to avoid packing in too much.
Frequently Asked Questions
Variations
- •
Peanut Butter Banana Protein Muffins
Swap the almond butter for smooth natural peanut butter in the same quantity. The flavour combination is a classic and the protein content stays virtually identical.
- •
Blueberry Banana Protein Muffins
Fold in 80g of fresh or frozen blueberries instead of the chocolate chips. The blueberries burst during baking and add pockets of jammy fruit alongside extra antioxidants.
- •
Chocolate Banana Protein Muffins
Replace 20g of the oat flour with 20g of raw cacao powder and use chocolate protein powder instead of vanilla. Top with a few extra dark chocolate chips for a deeply chocolatey muffin that still hits your protein goals.
- •
Banana Protein Muffins with Walnuts
Add 40g of roughly chopped walnuts to the batter along with the oats. Walnuts bring omega-3 fatty acids and a lovely crunch that contrasts beautifully with the soft muffin crumb.
Substitutions
- •Almond butter → Sunflower seed butter (A 1:1 swap that makes the recipe nut-free. The flavour is slightly more neutral but the texture is almost identical.)
- •Coconut oil → Light olive oil or avocado oil (Use the same quantity. These neutral oils keep the muffins moist without adding any coconut flavour.)
- •Maple syrup → Raw honey or agave syrup (Both work as a direct 1:1 swap in terms of volume. Honey adds a slightly more floral sweetness.)
- •Eggs → Flax eggs (Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water per egg and let sit for 5 minutes. This makes the recipe vegan and egg-free, though the muffins will be slightly denser.)
- •Greek yogurt → Coconut yogurt (full-fat) (Use full-fat coconut yogurt for a dairy-free version. The muffins will be slightly less protein-dense but will still hold together well and taste great.)
- •Whey protein powder → Pea protein or brown rice protein blend (Plant-based protein can absorb more liquid. If the batter feels very thick, add an extra 2 tablespoons of Greek yogurt or a splash of almond milk to loosen it slightly.)
🧊 Storage
Store in an airtight container at room temperature for up to 2 days. Refrigerate for up to 5 days. To freeze, wrap each muffin individually in cling film and place in a zip-lock bag. Freeze for up to 3 months. Thaw overnight in the fridge or microwave from frozen for 40 to 50 seconds.
📅 Make Ahead
These muffins are excellent for meal prep. Bake a full batch on the weekend and refrigerate or freeze for the week ahead. The batter can also be prepared the night before and stored covered in the fridge, then baked fresh in the morning. Add 2 to 3 extra minutes to the bake time if cooking from a cold batter.
