Heat the oven to 180 ° C.
Separate yolks from whites and whisk them in a mixer with all the other ingredients except protein and blueberries.
Add blueberries and mix gently.
Separately whisk the whites with a pinch of salt to steep peaks.
Now slowly and very carefully put the protein into the dough to a homogeneous mass, try not to overdo it with mixing, otherwise, the cupcakes do not rise.
Then spread the dough into silicone moulds 2/3 of their height.
From above you can decorate with nuts or seeds.
Bake for about 20 minutes, after which it is necessary to turn off the oven and not to take out to let them cool down for 7 minutes.
Then take out, cool the cakes completely and only then get them out of the moulds. That's all! Bon Appetit!
