Ingredients

70 g butter
20 to 30 g sugar, or half and half sugar / artificial sweetener. Adjust the sweetener level to your preference.
A good pinch of salt
2 eggs
juice of 1/2 lemon
3 tablespoon rum
90 ml milk
125 g whole wheat flour
1 teaspoon baking powder

Preparation === Let the butter be soft, i.e, microwave for a few seconds or remove it from the fridge in time early enough. Mix butter and sugar well.

Slowly, each time adding only a bit of liquid, add the 2 eggs, lemon juice, rum, and milk.

Finally, mix the baking powder into the flour, add to the dough, and mix well. Let sit for a few minutes, and then bake in a waffle iron.
