1/3cupplain whole milk Greek yogurt, or sour cream
lemon icing
1 1/2cupspowdered sugar
2-3tbsplemon juice
2tspvanilla extract
Instructions
Preheat oven to 350 degrees. Grease a loaf pan generously with oil or butter.
In a large bowl, toss the sugar with the lemon zest until the zest is distributed. Then, beat with the butter for 2-3 minutes until fluffy. Whip in eggs, one at a time, until incorporated. Beat in the lemon juice and vanilla.
Add the flour, baking powder, baking soda, and salt. Beat until just combined. Measure in the yogurt and whip until smooth.
Pour the batter into the prepared loaf pan. Bake 50-60 minutes until a toothpick inserted in the center comes out clean. If the loaf begins to brown too quickly, tent with foil. Let cool in the pan 5 minutes, then slide a knife around the edges to loosen and invert the loaf onto a wire rack. Flip upright and cool 10 minutes more.
To make the glaze, whisk together the powdered sugar, lemon juice, and vanilla until a thick but drizzly icing forms. If needed, add more powdered sugar to thicken, or a bit of milk or water to thin. Add thinly sliced strips of lemon zest, as desired. Spoon the icing over the loaf cake. Let set 5 minutes. Slice and serve warm or at room temperature.
