Milk

Most whey powders contain soya lecithin, which counts as soya. Check the tub.
Oat drinks count as a gluten cereal under UK labelling unless made from certified gluten-free oats.

Flags follow UK labelling rules and come from the ingredients as listed, not from any particular brand. Check the packet before cooking for somebody with an allergy.

Ingredients

Whey protein isolate1 scoop, about 30 g
Values for an unflavoured or lightly flavoured isolate. A concentrate or a blend carries more fat and carbohydrate at the same scoop.
Espresso1 shot, about 30 g
Cocoa powder2 tsp, about 6 g
Oat milk200 ml
IceA large handful
SaltA tiny pinch

Method

Stir the cocoa into the hot espresso until it dissolves, then leave to cool for a few minutes.
Pour the oat milk into the blender, add the coffee mixture, whey, salt and ice.
Blend for twenty seconds and pour. It will be frothy; that is the oat milk.

Worth knowing

Oat milk carries the most carbohydrate of the plant milks and is the reason this tastes sweet with nothing added. Soya milk in its place is lower and has more protein.
Cocoa dissolved in the hot coffee first is the difference between a mocha and a coffee with brown specks in it.
