Place ¼ cup of coconut flakes on a sheet pan; bake at 325°F for 4-6 minutes, or until coconut flakes just begin to turn brown. (Tip: watch closely as the coconut flakes can burn quickly!)
Meanwhile, whisk together all of the remaining ingredients in a medium bowl until well combined.
Place a large griddle over medium-low to medium heat. Once hot, grease well with butter and add 2 Tbsp of batter. Cook for 3-5 minutes, or until bubbles begin to appear on the surface of the pancake. Flip and cook for 3-5 more minutes, or until pancakes are golden brown.
Repeat with remaining batter. (Tip: Place the cooked pancakes on a pan in a 200°F oven to keep them warm while the others are cooking.)
Top pancakes with toasted coconut and serve with maple syrup.
