Preheat oven to 350°F. Line a muffin tin with paper liners or oil cups very lightly.
In a large bowl, stir together oat milk and apple cider vinegar. Mixture will curdle slightly. Don’t fret. Set aside.
Meanwhile, in a separate bowl, combine flour, baking powder, baking soda and salt.
Add oil, sugar, vanilla, lemon juice and zest to the oat milk mixture, stir to combine.
Add dry ingredients to wet and stir until well combined. Gently spoon batter into lined muffin cups until each is 3/4 full.
Bake about 20 minutes or until cupcakes are golden and slightly pebbly on top. They should spring back when lightly touched. Let cool completely before dipping tops in glaze.
Lemon Glaze 1-1/2 cup powdered sugar, sifted
juice of 1 lemon
Combine powdered sugar and juice in a small bowl. Stir until thick and smooth.
Dip cupcakes, top side down, into glaze, coating tops well. Then set right side up on a plate and let cupcakes sit a few minutes. Glaze will harden to a pretty gloss.
