Most people over-mix their muffin batter. The result is misshapen hockey pucks rather than moist rounded muffins. To avoid this, sift together all dry ingredients in a bag and mix the wet ingredients in another bowl. Once wet ingredients are mixed together, whisk in the dry until combined. The batter will be a little lumpy, but it’s supposed to be! Let sit five minutes before baking to allow the gluten to rest. Voila! Perfect muffins that look like muffins should!
Preheat oven to 350 degrees Fahrenheit. Grease a muffin pan.
In a plastic bag or bowl, combine flour, oats, sugar, and baking powder.
In a large bowl, combine oil, egg, vanilla, milk, and yogurt. Add in dry ingredients. Add to muffin cups and bake for 25 minutes.
