First, combine the almond milk and vinegar in a measuring cup, stir well, and set aside.
1 tbsp vinegar, ¾ cup almond milk
Preheat oven to 350 degrees. Line a muffin pan with cupcake liners.
Place all dry ingredients into a medium size bowl and whisk well.
1½ cups flour, 1¾ tsp baking powder, 1 tbsp cornstarch, ¼ tsp baking soda, ¼ tsp salt
Next, mix butter and sugar on medium-high until fluffy.
1 cup sugar, ¼ cup butter
Then add oil and mix again for about 1 minute.
¼ cup vegetable oil
Add eggs and vanilla bean paste, then mix slowly until combined.
2 large eggs, 1 tbsp vanilla bean paste
Mix half of the dry ingredients into the wet mixture until combined. Then, add the remaining dry ingredients and almond milk mixture. Mix this in the medium until fully combined.
Pour batter evenly into cupcake liners about 2/3 of the way. Bake for 14 to 19 minutes until a toothpick comes out clean.
