Preheat oven to 350° F. Line a large sheet pan with parchment paper.
In a medium bowl, whisk all dry ingredients until combined.
In a large bowl, whisk all wet ingredients.
Slowly add the dry ingredients to the wet ingredients. I did mine in three parts and used a silicone tipped wooden spoon. Mix together until just combined. Fold in mix-ins of choice.
Using a silicone spatula, spread the batter evenly on to the sheet pan. Use the silicone spatula to smooth the batter to a uniform thickness throughout.
Bake at 350° F for 20 minutes. The edges will be slightly browned and a toothpick will come out clean when inserted.
Cut as desired. Top with plenty of butter and real maple syrup and enjoy!
