Vegan Cupcakes

  • 1 1/2 teaspoons apple cider vinegar
  • 3/4 cup non-dairy milk, room temp (curdled with vinegar)
  • 1 3/4 cups oat flour (about 210 -215 g), sifted (see notes)
  • 1/4 cup tapioca flour (30 g)
  • 2 Tbsp cornstarch or arrowroot starch
  • 2/3 cup fine sugar
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/3 cup melted coconut oil or vegan butter (or a neutral oil)
  • 1 teaspoon vanilla extract

Frostings


Instructions

  1. Once cool, decorate with a frosting of choice. To create fluffy swirls of frosting, use a pastry bag with a star tip. For a touch of glitter, sprinkle some raw sugar on top!

Notes

Batter Tip – Oat flour varies by brand/grind. Start with 210-215 g (about 1 ¾ cups) and add up to 230-240 g (about 2 cups) if the batter is too thin. Always sift for best results. Homemade oat flour (from blended rolled oats) is often coarser and may require the full 2 cups.

Gluten-Free Blend: You can also use a gluten-free all-purpose flour blend without xanthan gum in place of the oat/tapioca mix. In that case, skip the extra starch and start with ⅔ cup milk.

Other Substitutes – Any neutral oil like avocado oil and light olive oil may be used in place of melted coconut oil or vegan butter. 

Flour Substitute-  A gluten-free all-purpose flour blend without xanthan gum can be used in place of oat flour. Because most blends already include starches, you can skip the extra 2 tablespoons of starch. In this case, start with ½–⅔ cup milk instead of ¾ cup — the batter should be thick and scoopable, not pourable. Texture will vary depending on the blend. 

Starch choice (if using oat flour): Cornstarch gives the lightest crumb; tapioca adds chew; arrowroot makes a tender cupcake.
