Preheat your waffle iron according to the manufacturer's instructions, typically to a medium-high setting. Grease the plates with cooking spray or oil.

In a bowl, whisk together 1 ½ cups of all-purpose flour, 2 tablespoons of sugar, 1 tablespoon of baking powder, and ½ teaspoon of salt until combined.

In another bowl, whisk together 1 ¼ cups of milk, 2 large eggs, ¼ cup of melted butter, and 1 teaspoon of vanilla extract until smooth.

Gently pour the wet ingredients into the bowl with the dry ingredients, stirring until just combined. Fold in 1 cup of pureed strawberries.

Pour about ¾ cup of batter onto the center of the waffle iron and cook for 4-5 minutes or until golden brown and crisp.

Remove the waffles from the iron and serve topped with fresh strawberries or your choice of toppings.
