140g(1cup)fresh blackberries, cut in half or thirds
Turbinado sugar, for sprinkling
Rolled oats , for sprinkling
Instructions
In a small bowl, whisk together the flour, quick cooking oats, baking powder, baking soda, and salt.
In a separate bowl, beat the butter and sugars for 2-3 minutes until light and fluffy.
Scrape the bowl down, then add the eggs & vanilla and mix until fully combined.
Pour in the buttermilk and mix until combined.
Fold in the dry ingredients until mostly combined, then add the blackberries and gently mix until evenly distributed.
Cover the bowl and allow to rest at room temperature.*
Meanwhile, preheat the oven to 425 degrees F and line a muffin pan with parchment liners.*
Divide the batter up between 10 muffin cavities, filling all the way up to the top. Sprinkle each muffin with turbinado sugar and rolled oats.
Bake the muffins for 5 minutes, then turn the oven down to 375 degrees F and bake for another 15 minutes. Do not open the door when you turn down the temperature.
Allow muffins to cool for a few minutes in the pan, then transfer them to a wire rack to cool completely.
Notes
Resting the batter allows the leaveners to activate and ensures the muffins bake up tall. If you're in a rush, you can skip this and bake them right away.
You can make your own parchment liners by cutting two squares of parchment paper per muffin. Press the two squares into a muffin cavity, then place a cup inside to hold it in place for a minute or two. Fill with the muffin batter and bake!
