Banana and skyr protein ice cream: 18 g protein per serving

The honest question about banana ice cream is whether it scoops like ice cream or slumps into a cold slurry within two minutes. It scoops, but only if the banana goes into the blender frozen solid and you keep added liquid to a minimum. This version makes four servings at roughly 18 g protein each and takes about ten minutes of actual work.

Preparation time and servings

Prep: 10 min. Cooking: 0 min (nothing is heated). Servings: 4.

The bananas need at least 4 hours in the freezer, ideally overnight, so slice and freeze them the day before. If you want a firmer scoop, allow another 30 to 60 minutes of setting time after blending.

Ingredients

• 400 g banana, peeled, sliced and frozen (about 3 medium bananas)
• 400 g plain skyr with no added sugar (around 0.2% fat)
• 30 g vanilla protein powder (one scoop)
• 40 ml milk or a plant drink
• 5 ml vanilla extract
• 1 pinch of salt (about 1 g)

Method

1. Peel the bananas before freezing and cut them into discs about 1 cm thick. A banana frozen in its skin is a lost cause.
2. Spread the discs in a single layer on a lined tray and freeze for at least 4 hours.
3. Take the skyr out of the fridge five minutes before you blend. Fridge-cold skyr stalls the blade and tempts you into adding liquid.
4. Put the frozen banana into a blender or food processor and pulse for 20 to 30 seconds until it looks like coarse crumbs.
5. Add the skyr, protein powder, vanilla and salt. Blend for 60 to 90 seconds, stopping two or three times to scrape the sides down with a spatula.
6. Add the milk one tablespoon at a time, and only if the mixture refuses to turn. Every extra millilitre comes back later as hard ice crystals.
7. Stop as soon as the mixture is smooth and glossy, like thick soft-serve. Blending past that point warms it and it starts to weep.
8. Serve straight away, or spread it into a shallow container and freeze for 30 to 60 minutes. If it sits for more than three hours, take it out ten minutes before eating.

Nutrition per serving

These figures are an estimate per serving of roughly 215 g, calculated from the quantities listed above. The real number shifts with how ripe the bananas are and which protein powder you use.

• Calories: about 190 kcal
• Protein: 18 g
• Carbohydrates: 28 g (mostly natural sugars from the fruit and dairy)
• Fat: 1 g

That is a good ratio for a dessert but thin for a meal. When you want the same ingredients to actually feed you, Greek yoghurt with fruit and walnuts built as a meal is the better call.

Variations and swaps

No protein powder. Drop the powder and raise the skyr to 500 g. A serving then lands around 15 g protein and 175 kcal, with a sharper, tangier flavour.

Chocolate version. Add 10 g unsweetened cocoa with the skyr. That is roughly 6 kcal more per serving and a noticeably darker, more bitter result, so you may want half a banana extra.

Creamier but heavier. 40 g peanut butter smooths the texture and makes it easier to scoop straight from the freezer, at about 60 kcal and 5 g fat more per serving.

Less sugar. Swap 100 g of the banana for 100 g frozen raspberries. You lose roughly 5 g of carbohydrate per serving and gain a sharp, fresh edge, but the mixture ends up looser.

Dairy-free. Use a soya yoghurt with at least 5 g protein per 100 g and a plant-based powder. Nothing else in the method changes.

Any leftover banana that has gone too soft to freeze well is better spent on banana and oat protein muffins, and a spoonful of lower-sugar homemade granola on top gives the scoop some crunch.

When to see a doctor

If skyr and milk reliably leave you bloated, crampy or running to the toilet, that is not a recipe problem and is worth checking properly rather than experimenting on your own for weeks. The same goes if you have diabetes or have been told to watch your sugar intake: a serving carries 28 g of carbohydrate, and that belongs inside the daily plan rather than on top of it.

In short

Frozen banana supplies the texture, skyr and powder supply the protein, and added liquid is the one ingredient that can ruin the lot. Four servings, roughly 190 kcal and 18 g protein each, ten minutes of work and no machine. It is best straight out of the blender; everything after that is a compromise.
