Allergens

Gluten
Milk
Eggs

Oats count as a gluten cereal under UK labelling and ordinary oats are milled alongside wheat. Certified gluten-free oats are a separate ingredient here.
Most whey powders contain soya lecithin, which counts as soya. Check the tub.

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

Rolled oats120 g
Dry weight.
Courgette150 g
Grated and squeezed in a tea towel until it stops dripping. Unsqueezed, the bake is soggy in the middle.
Cocoa powder5 tsp, about 15 g
Egg2 large, about 110 g
Honey3 tsp, about 21 g
Whey protein isolate1 scoop, about 30 g

Baking powder1 tsp
SaltA pinch

Method

Heat the oven to 180°C and line a 20 cm square tin with baking paper.
Grate the courgette, wrap it in a clean tea towel and wring it out over the sink. You should get a small cup of green water from it.
Whisk the eggs and honey, then stir in the courgette, oats, cocoa, whey, baking powder and salt. Spread into the tin and bake for twenty-five minutes until set.
Cool in the tin. It tastes of cocoa, not courgette, and nobody who did not watch you make it will know.

Worth knowing

The courgette adds almost nothing to the numbers and a lot to the texture. It is the reason the square stays soft two days later.
Cocoa powder is bitter and the honey is set against it. Cut the honey and the square goes from dark chocolate to plain cocoa quickly.
