Preheat the oven to 375F and spray your muffin tin with Pam Baking Spray.

In a large bowl mix the eggs (room temperature) milk, greek yoghurt, melted butter, vanilla extract.  Add the mixed berries.  You can use either fresh berries, or the frozen berries. I’ve set out the quantities in the ingredients list above. These are your wet ingredients.

In a medium bowl, blend together the all purpose flour, whole wheat flour, brown sugar, cinnamon, salt, baking soda.

Carefully stir the dry ingredients into the wet ingredients, just enough to blend. 

Using a cookie scoop or ice cream scoop, drop the muffin batter into the muffin cups.

Place the muffin pan in the centre of a preheated oven and bake for 20 to 25 minutes.

Place on a wire rack to cool, and store in an airtight container.

These muffins freeze really well, I usually pop a half dozen into a zip lock bag.
