Prepare the PanPreheat your oven to 350°F (175°C).Grease a bundt pan generously with vegan butter or non-stick spray. Lightly dust with flour and set aside. Mix the Dry IngredientsIn a medium bowl, whisk together the flour, baking powder, salt, and lemon zest. Set aside. Make the BatterIn a large bowl, mix together the oil sugar until well combined. (about 2–3 minutes). Add the non-dairy milk, lemon juice and vanilla extract. Mix until smooth.
Add the dry ingredients into the wet ingredients. Mix gently until just combined — do not overmix.
Fold in the blueberries, coating lightly in flour first if using fresh berries to prevent sinking.
Bake the CakePour the batter evenly into your prepared bundt pan. Bake for 45–55 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 10–15 minutes, then flip onto a wire rack and cool completely.
Make the Lemon GlazeIn a small bowl, whisk the confectioners’ sugar and lemon juice until smooth and pourable. Once the cake is completely cooled, drizzle the glaze over the top and let set.
