Preheat oven to 375° F. Line a 12-cup muffin tin with liners.
In a large bowl, whisk together the flour, baking powder, salt, and cinnamon. Add the eggs, milk, maple syrup, and olive oil, stirring only enough to dampen the flour (batter should not be smooth). Add the berries and mix lightly. Spoon batter into the muffin pan, filling each cup about two-thirds full. Let batter rest for 10 minutes.
Place in the oven and bake for about 20-25 minutes or until lightly browned. Remove from oven and let cool in the pan for 5 minutes, then turn out onto a wire rack to cool completely.
