Oat and banana muffins

These oat-banana muffins are the ideal homemade snack: 11 g of protein for 184 kcal each, with no added sugar (the banana sweetens them). Made from oats, banana, eggs and whey, they are a great replacement for industrial bars and pastries. Make six at once for ready snacks all week.

At 184 kcal and 11 g of protein, these muffins suit cutting as well as a snack around training. For more protein, increase the whey or add quark to the batter. For bulking, fold in dark chocolate chips, nuts or peanut butter. The oat-banana-egg base stays the same.

Blend the ingredients, divide into moulds (silicone, no grease) and bake 20-25 minutes at 180 °C: the muffins are ready when a knife comes out clean. Very ripe bananas give more sweetness and moisture. They keep 3-4 days at room temperature in a box, or freeze individually.

A shop-bought protein bar or pastry is often a lot of sugar, refined oils and a long ingredient list. These homemade muffins do better on every front: the banana replaces added sugar, the oats bring fibre, the whey protein, and you know exactly what you're eating. All for a fraction of the price.

It is also a matter of habit: having a stock of homemade snacks on hand stops you caving to industrial snacking when hunger strikes between meals. Make a batch at the weekend, keep some in the freezer, and you always have a healthy, protein-rich option within reach — far more effective than willpower for sticking to a diet.

The oat-banana-egg base accepts dozens of variations. Add a handful of blueberries or raspberries for a fruity note, grated apples with a little cinnamon for an autumn version, unsweetened cocoa for a chocolate muffin, or a spoonful of almond butter for quality fats. Each addition changes the taste without upsetting the structure. Just avoid going beyond a small handful of filling per muffin so the batter rises properly and does not collapse in the middle. For an even richer taste, lightly toast the oats dry in a pan before blending them: they develop very pleasant nutty notes.

To adapt the recipe to your diet, replace the semi-skimmed milk with a plant drink, choose certified gluten-free oats if you are sensitive, or use a whey isolate to limit lactose. For an even higher-protein muffin, add 100 g of 0% quark and one extra egg, slightly reducing the milk. You can also replace one banana with unsweetened apple sauce: the texture stays moist and the taste more neutral, handy for palates that do not like banana. Always keep the same weight of batter per mould so all the muffins bake at the same time and have comparable macros, which makes tracking easier.

The first mistake is using bananas that are too firm: they bring little sweetness and moisture, and the muffins come out bland and dry. Choose spotted, almost brown bananas. The second mistake is overbaking: as soon as a knife comes out dry, take the tray out, because residual heat finishes the cooking. An oven that is too hot browns the outside before the inside is cooked, giving a cracked dome and a damp centre. Check the real temperature with an oven thermometer if your muffins turn out inconsistently. One last useful cue: the muffins should spring back slightly when you press the top with a finger, a sign they are cooked through.

Watch out for the whey too: some powders absorb a lot of liquid and make the batter dry. If it looks too thick, add a spoonful of milk. Let the batter rest for five minutes before baking so the oats hydrate, which clearly improves the texture. Finally, cool them on a rack instead of leaving them in the tin: trapped steam would make them sticky and hard to unmould cleanly. For easy unmoulding without fat, use paper cases or flexible silicone, and keep them overnight in an airtight box so they stay soft.
