Grease TWO standard loaf pans (9" x 5" x 4.5") and preheat your oven to 375°F If you do not want to make 2 loaves of this bread just divide all the ingredients by half and double check your math!
Melt the vegan butter or coconut oil & reserve
Combine the plant milk with the lemon juice then add the vanilla extract & lemon zest, let stand to thicken for about 5 minutes. (soy milk is the only plant milk that will thicken like buttermilk)
In a large mixing bowl combine the flour, sugar, baking soda & salt & whisk together to incorporate all the ingredients very well.
Add the liquids: the mock buttermilk, vanilla & the melted vegan butter or oil & the applesauce ~ whisk smooth.
Fold in the blueberries then divide the batter evenly between your 2 prepared loaf pans.
Bake immediately in a preheated 375°F oven for 10 minutes then turn the oven temperature down to 350°F for another 25 minutes.
The loaves should be almost baked by 35-45 minutes but definitely check them at the 30 minute mark just to be sure, as all ovens bake differently.
I like to do the "toothpick" test to make sure there is no raw batter, if there is you will want to turn the oven down even more to 300°F to continue baking all the way without risking over browning or drying of the edges of your bread.
Cool the loaf pans on a wire rack until you can safely touch them with your bare fingers then flip them out carefully to cool the rest of the way.
Once the breads are completely cooled, whisk together the confectioner's sugar with the lemon juice to smooth.
Pour over the bread and then zest a lemon over top. *Obviously if you are keeping this bread low sugar you will omit this glaze OR use a powdered monk fruit sugar glaze
