Lemon Cake Donuts
Lemon juice and zest brighten these rich, dense buttermilk donuts. They're dipped in a lemon glaze and sprinkled with more zest before serving.
If you want to make all donut holes, flatten dough to 3/4 to 1 inch thick. Use a floured 1 1/2-inch cutter to cut out about 42 rounds. Cook, flipping a few times, until deep golden brown all over, 2 1/2 to 3 1/2 minutes total.
