Preheat oven to 375 deg. F.
Whisk dry ingredients in one bowl and set aside.
Mix wet ingredients in another bowl. Add wet mixture to flour mixture, add in berries and chocolate chips, using a spatula to very gently fold mixtures together. Batter will be lumpy, do not over-mix.
Spoon batter into greased or lined mini muffin tin and bake at 375 deg. F. for 10-12 minutes, or until tops are golden brown. Remove from oven and allow to cool.
