Ingredients for 1 serving

1 serving

Check off ingredients as you go.

Contains milk, peanuts. Check the labels on packaged ingredients:

  • whey protein powder. Protein powders differ by brand in protein per scoop, sweeteners and allergens; check the label.
  • peanut butter. Most peanut butter contains added salt, and some contains palm oil or sugar; this figure is for the unsalted kind.

Cooking steps

  1. Pour the milk into the blender jug and add the protein powder.

  2. Blend on low for 10 seconds, until no dry protein powder is left on the surface or the sides of the jug.

  3. Add the peanut butter and the frozen banana. Blend on high for 30 to 45 seconds, until smooth and lightly frothy.

  4. Pour into a glass. If it is too thick to drink comfortably, blend in 2 to 3 tablespoons of cold water.

The useful detail

Blend the protein powder into the milk before anything thick goes in. Added last, it sits on top of the banana and peanut butter, sticks to the jug walls and leaves dry pockets; blended first, it dissolves in seconds.

Make it work for you

One serving is One glass, about 350 ml. You can switch to a smaller portion in the ingredients above; it is three quarters of this, and it contains correspondingly less energy and protein. It is an option, not a goal.

  • Ground almonds instead of peanut butter

    Milder and a little less smooth; blend for an extra 20 seconds.

    Per serving: about the same energy, about the same protein, about the same fat.

    Allergens: Removes peanuts but adds tree nuts (almonds).

  • Plain skyr instead of protein powder

    Thicker and tangier, with less protein. Use 150 ml of milk instead of 220 ml so the glass stays the same size; the figures here keep the full 220 ml.

    Per serving: about 10 kcal more, about 2 g less protein, about the same fat.

  • Unsweetened soya milk instead of semi-skimmed

    Slightly thinner, with a nutty note that suits the peanut butter.

    Per serving: about 25 kcal less, about 1 g more protein, about the same fat.

    Allergens: Adds soya. The whey protein powder still contains milk.

Estimated nutrition

Per standard serving, calculated from the ingredients above. Nutrition changes with substitutions, brands and how much oil stays in the pan.

The protein powder and milk carry most of the protein; the peanut butter adds most of the fat. Protein powders differ by brand, so check yours against the figures here.

Show calculation notes

Each ingredient’s weight is multiplied by its USDA FoodData Central values per 100 g. The whole recipe is added up and divided by 1. Raw weights are used for meat, fish and vegetables; beans and lentils are drained weights. All of the oil is counted as eaten. Added salt is not included; sodium from stock, bread, cheese and tinned food is.

Storage and reheating

In the fridge
Best drunk straight away. If you keep it, cover it and refrigerate within 2 hours, and drink it within 24 hours; it separates, so shake or stir it first.
Reheating
Not for reheating. Serve cold.

Checked against US Food and Drug Administration, Refrigerator and Freezer Storage Chart, USDA Food Safety and Inspection Service, Leftovers and Food Safety, FoodSafety.gov, Safe Minimum Internal Temperatures and FoodSafety.gov, Cold Food Storage Chart. UK guidance from the Food Standards Agency is shorter, at two days for most leftovers.
