Preheat oven to 350*. Combine first 4 ingredients in a medium bowl and set aside.
In a large bowl, combine remaining ingredients (except berries) and stir until well blended.
Pour wet ingredients into dry and stir until JUST combined - don't over mix!
Add berries (I had frozen mixed berries on hand) and stir until just incorporated.
Pour into lined jumbo muffin tin, sprinkle tops with sugar, and bake for 30-40 minutes or until golden brown.
Remove from oven and let cool in pans (about 20 minutes) and move to cooling racks.
Enjoy your delicious, soft, easy-to-make muffins! :)
