Preheat oven to 350. Apply non-stick spray/oil to 8 wells of mini-bundt pan or standard-sized muffin pan. If using a silicone baking pan, place on a firm baking sheet.
In a small bowl, mix together dry ingredients (not including berries) and set aside. In a separate bowl, whisk together liquids until well blended. Combine dry ingredients with liquids and mix well.
Fold in blueberries, then pour into prepared pan and bake until cooked through, approximately 18 minutes. Tops will spring back when lightly touched.
Remove from oven and allow to cool a few minutes on cooling rack. Remove from pan and allow to cool. Serve warm or store in the fridge.
