Melt 1/4 cup butter in a small saucepan over medium heat on the stove or in the microwave.
1/4 cup butter
In a medium-sized mixing bowl, whisk together melted 1/4 cup butter, 2 cups liquid whey, 1/2 cup Greek yogurt, 2 tbsp maple syrup, 1 tsp vanilla extract, and 1 egg until well combined.
Gradually add the dry ingredients including 2 cups all-purpose flour2 tsp baking powder to the wet ingredients, stirring until just combined. Be careful not to overmix the batter.
2 cups all-purpose flour, 2 tsp baking powder
Allow the wet mixture to rest for about 5 minutes. This helps activate the baking powder and allows the batter to thicken slightly.
Preheat the waffle iron and lightly grease it with butter or non-stick cooking spray.
Pour a cup of batter onto the preheated waffle iron, following the manufacturer's instructions for the recommended amount. Close the waffle iron and cook until golden brown and crisp. Mine take around 3 minutes to cook on medium heat.
Carefully remove the waffle from the iron and repeat the process with the remaining batter.
Avoid overmixing: To achieve a soft and fluffy texture, be cautious not to overmix the batter. Overmixing can lead to gluten development, resulting in denser waffles.Preheat the waffle iron: Make sure the waffle iron is properly heated before pouring the batter so that the waffles rise and cook evenly and most importantly peel off easily from the iron once baked.Extra protein: Add 1 scoop of plant-based protein powder such as vanilla protein powder to the batter to increase the protein content.Storage: Cooked waffles can be stored in an airtight container in the fridge for up to 4 days. To freeze cooked waffles, allow them to cool and separate, stack them with parchment paper in between, and store them in an airtight container in the freezer for up to 3 months in the freezer.
