This vegan lemon loaf is super easy to whip up and bursting with zippy, lemony flavor! It's a perfect dessert for everything from special dinners to just enjoying with an afternoon cup of tea.
Preheat the oven to 350°F. Grease the bottom and sides of an 8-inch loaf pan (Note 2).
Whisk the flour, sugar, baking powder, and salt together in a large mixing bowl.
In a small container such as a liquid measuring cup, stir together the yogurt, oil, lemon juice, lemon zest, lemon extract, and yellow food color, if using.
Pour the yogurt mixture into the bowl with the flour mixture. Stir the ingredients together just until they're combined.
Pour the batter into the prepared loaf pan, smoothing out the top with a spoon or spatula.
Bake the loaf until the edges are golden brown and a toothpick inserted into the center comes out clean. Place the loaf on a cooling rack and allow it to cool completely before removing it from the pan.
When the loaf is cool, make the glaze by stirring the powdered sugar and lemon juice together in a small bowl. Add more powdered sugar if it seems too thin, or more lemon juice if it seems too thick.
Remove the loaf from the pan. Spread the glaze over the top and sides of the loaf. Let it sit until the glaze has fully set.
Slice the loaf. Serve.
