Optional Toppings: More maple syrup or peanut butterchopped nuts, butter, whipped cream
In a large bowl, combine oat flour, baking powder, salt, nutmeg and cinnamon. Whisk together to combine.
In separate medium bowl, whisk the eggs. Add milk, olive oil, peanut butter, maple syrup and vanilla extract. Whisk until completely combined. Pour into flour mixture. Stir with spatula or spoon until just combined, small lumps in the batter are fine. Let the batter sit for 10 minutes so the oat flour can soak up the moisture (optional but recommended), batter will be pretty thick.
Plug in and preheat your waffle iron. Gently stir the batter one more time to combine. Pour some batter into center of heated waffle iron. It should fill most of the surface area, but not pour out the sides when closed. Cook each waffle according to your waffle iron directions (usually 3-5 minutes). Waffles should be crisp and golden brown. Serve right away or place waffles in oven at 200ºF to keep warm and crisp until serving. Top with desired toppings. Optional sides: Eggs, sausage, bacon, yogurt or fruits
