Grind the softened butter with sugar. Add eggs to the resulting mass, and beat with a mixer until a homogeneous mass is obtained.
Mix all the bulk ingredients in a separate container.
Using a mixer, we combine the two resulting masses, periodically pouring in the milk.
We put the resulting dough in a prepared heat-resistant form, level it, and put it in the oven, preheated to 180 degrees for 30 minutes. Check the readiness of the biscuit with a toothpick – it must remain dry.
Free the finished biscuit from the mold, cool, and use as directed.
