Preheat oven to 400°.
Place the berries into a medium-sized bowl. Add the extra flour and sugar to the berries, gently mix, and set aside.
Use a stand or hand mixer and beat the eggs, butter, oil, milk, yogurt, and vanilla. Start at a slow speed as the mix is runny and may splatter.
Add the sugar and continue to mix at medium speed.
Add flour and baking powder and mix until fully incorporated.
Gently fold the flour/sugar-coated berries into the mixture.
Spray a muffin pan with non-stick spray.
Fill the muffin tin 3/4 of the way to the top.
Bake for 17-19 minutes.
The edges will be slightly brown.
Cool on a wire rack.
