This recipe comes together quickly, and thanks to the olive oil is inherently moist and tender.
Preheat oven to 425 Prepare muffin tins by putting papers in every other well.
In a medium bowl, whisk together dry ingredients. To the dry ingredients add the milk, olive oil, eggs, and vanilla and whisk until combined and then fold in berries using a rubber spatula.
Using a scoop or pouring carefully fill each paper until just below the top of paper. Let batter then sit for 15 minutes before placing in oven.
Bake at 425 for the first 7 minutes. Reduce temperature to 350 and cook for the remaining 20 minutes. Test with toothpick to ensure it comes out clean. Remove from pans and cool on wire rack.
Dust with powdered sugar after cooling.
