In a large bowl, whisk together the dry ingredients.
In a smaller bowl, whisk the eggs, melted butter, milk and vanilla until well combined
Add the wet ingredients to the dry, and mix until just combined. Mixture will be lumpy.
Fold in the blueberries.
Spray the waffle iron with baking spray, and cook waffles until light brown and slightly crispy.
Serve dusted with powdered sugar and a little maple syrup.
Add a little cinnamon to the batter (about a teaspoon) - it will add a really delicious warmth to the waffles.
Grate a little lemon zest into the batter, for a fresher, brighter flavor.
Can you freeze waffles? Absolutely! Just place a little parchment between each and store in a freezer zip lock bag. They'll stay good for 3 months. Just reheat in the toaster! If you are planning to freeze them, undercook them slightly - as they'll brown up when you toast them.
What is the difference between pancake and waffle batter? In a nutshell, waffles contain more sugar and more butter than a typical pancake
What goes good with blueberry waffles? Whipped cream, maple syrup, and powdered sugar are my go-tos! Blueberry sauce is also good, but I like a scoop of vanilla ice cream on waffles - then it's a dessert!
Fresh blueberries or frozen? Either will work just fine. Frozen blueberries contain a little more moisture, and will "bleed" a little into the batter, but that won't affect the flavor at all.
