Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
In a bowl, whisk together flour, sugar, poppy seeds, baking powder, baking soda, and salt.
In another bowl, mix plant-based milk, lemon juice, zest, coconut oil, vanilla extract, and vinegar.
Gradually combine wet and dry ingredients, stirring until just mixed (don’t overdo it).
Scoop batter into the muffin tin, filling each cup about ¾ full.
Bake for 18 minutes or until a toothpick comes out clean.
Let them cool for 10 minutes, then devour.
