Add the yeast, sugar, and warm milk to a bowl. Let proof until frothy, about 15 minutes. Meanwhile, measure out the other ingredients. Mix them all together until a thick but wet dough forms (kind of like cookie dough). Let proof for 1 hour. Measure in 1/4 cup sizes, roll into balls and place into greased muffin tins. Preheat the oven to 350F while letting the cakes rise a second time, for about 20 minutes. Bake until puffed and golden about 30 minutes.
