Ingredients

  • 1 cup (240ml) milk
  • 1 cup (100 g) old-fashioned rolled oats (you can also use quick oats)
  • 1 tsp vinegar
  • ½ cup (115 g) unsalted butter, melted
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 ½ cups (180 g) all-purpose flour
  • ½ cup (110 g) brown sugar (you can also use honey for healthier alternative)
  • 1 tsp baking powder
  • ½ tsp baking soda
  • ½ tsp ground cinnamon
  • ½ tsp salt
  • About 1 cup adders of choice (see notes below for list of variations)

Instructions

  • Preheat oven to 400° F.
  • In a small bowl, combine the milk, oats, and vinegar. Set aside while you prepare the rest of the ingredients. It's good for the oats to soak for at least 15 minutes.
  • Meanwhile, prepare a muffin tin by greasing with nonstick spray or use cupcake liners.
  • Melt the butter in a microwave safe bowl. Set it aside to begin cooling. In a mixing bowl, combine all the dry ingredients - flour, sugar, baking powder, baking soda, and cinnamon. Whisk together.
  • Add eggs and vanilla to the melted butter and whisk together. Add the butter mixture and the oats mixture to the bowl of dry ingredients. Gently mix together until combined.
  • Fold in adder of choice. (See tips above for a list of variations!) Pour batter into the muffin tins. Batter should reach almost to the very top. If you wish to sprinkle something on top (coarse sugar, oats & cinnamon sugar, chocolate chips) do so now before baking.
  • Bake* for 17-20 minutes (might take a minute or two longer if your adder is fruit). Let them cool in the muffin tin for a few minutes before transferring to a cooling rack. Store in an airtight container once cooled.

Notes

BAKING TIME:
  • Mini muffins take about 12-14 minutes.
  • Muffins with fruit in them will take a couple minutes longer compared to plain or chocolate chip.
