Step 1

Preheat the oven to 350 degrees F. Spray 1 loaf pan and set aside.

Step 2

In a medium bowl mix together flour, baking powder, and salt. Set aside. In a separate bowl, combine coconut oil and lemon juice. Set aside.

Step 3

In a stand-up mixer or an electric handheld mixer, beat together the butter, sugar, and lemon zest until light and fluffy. With the motor running, add vegan sour cream, scraping down the sides as necessary. The mixture will appear to have separated at this point, but it will come back together.

Step 4

Alternating wets (oil and lemon juice) and dries (flour mixture) add in three batches, scraping down the sides as needed, ending with the flour mixture until it just comes together. Do not over-mix.

Step 5

Pour batter into prepared loaf pan and smooth top. Bake until cake is golden brown (about 50-55 minutes), and a toothpick comes out clean when inserted in the middle. Remove from the oven and let cool for 30 minutes. Flip out onto wire racks and allow the loaf to cool completely.

Step 6

To make the lemon glaze, combine powdered sugar and lemon juice until smooth and pourable. Pour over the cooled loaf pan. The glaze will harden as it cools. Keep at room temperature, tightly wrapped, for up to 3 days. This cake can also be stored in the freezer for up to 6 weeks.
