What you will need:
3 ounces of unsalted butter
1 cup of granulated sugar
2 eggs
1/2 cup of milk
1 1/3 cup of all purpose flour
1 teaspoon of baking powder
1/2 teaspoon of salt
2 tablespoons of lemon zest
For the glaze:
1/3 cup lemon juice
2 cups of powdered sugar
1 tablespoon of vegetable oil
1 tablespoon of water
Cream the butter with the granulated sugar. Once the butter and sugar is light and fluffy, add the 1/2 cup of milk. Add the eggs in one at a time. The mixture will be really soupy.
Sift the flour, baking powder, and salt together and then add the dry ingredients to your batter. Mix just until the batter comes together. It will be very creamy and light yellow. Fold in the lemon zest when done. You can portion the batter into a muffin pan or a bread loaf pan. Bake at 350 degrees for about 35 to 40 minutes if you are using the loaf pans (about 15 minutes for muffins) until light brown on top.
While the bread is baking, mix the lemon juice, water, oil, and powdered sugar together in a bowl. This will become your glaze.
Once the bread is done and cooling on a rack, pour the glaze over the top. Make sure you have a piece of parchment paper or a paper towel underneath when you pour the glaze. Unless you mind cleaning up lemony sugary goodness all over your countertop.
