Step 1

In a medium bowl mix buttermilk with oats and leave to hydrate while preparing the rest.

Step 2

Turn on the oven at 350°F/180ºC.

Step 3

Line 12 muffin cups with paper liners. Or butter and flour them. Reserve.

Step 4

In a large bowl, mix flour, baking soda, salt, and baking powder. Add the sugar and mix.

Step 5

Add the oil and egg to the oatmeal mixture. Mix everything well without beating.

Step 6

Add the wet ingredients to the dry ingredients and mix with a spatula or hand mixer, and only until just combined, don’t be tempted to beat it as it will result in tougher and less fluffy muffins.

Step 7

Fill the muffin tins or paper cups 3/4 full, dividing the mixture as evenly as possible.

Step 8

Cook 20-25 minutes, or until a tester comes out dry. Let cool completely on a metal rack.
