These soft whey waffles can be prepared in 20 minutes, perfect for meal prepping or busy mornings. Using liquid whey leftover yogurt making, this quick and easy recipe makes a delicious breakfast, snack, or even dessert. Packed with protein, these soft waffles are the best way to use up leftover whey.

Since making yogurt in the Instant Pot I’m forever looking for ways to use leftover whey from yogurt making. My whey bread, whey scones, and whey pancakes are other good examples to utilize it in other recipes to reduce foo waste. Leftover whey adds a soft and fluffy texture to these waffles and the whey and yogurt add extra protein too. Win win!

I love to meal prep these waffles for an easy breakfast or snack for the kids. Simple make the batter 1-2 days ahead and store it in the refrigerator or cook a batch of waffles and freeze them. Reheat the frozen waffles in a toaster oven or oven when ready to eat. Top them with extra yogurt and fresh fruit for a balanced breakfast or snack!

Ingredients
 
 

  • 1/4 cup butter unsalted
  • 2 cups liquid whey
  • 1/2 cup Greek yogurt
  • 1 egg
  • 1 tsp vanilla extract
  • 2 tbsp maple syrup
  • 2 cups all-purpose flour
  • 2 tsp baking powder

Instructions
 

  • 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.
    2 cups liquid whey, 1 egg, 1 tsp vanilla extract, 2 tbsp maple syrup
  • Gradually add the dry ingredients including 2 cups all-purpose flour 2 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.
  • Serve the warm whey waffles with your favorite toppings. Enjoy!

Notes

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.

Ingredients and substitutions

  • Liquid whey – You’ll need 2 cups of leftover liquid whey from yogurt or cheesemaking. You can substitute the liquid whey with milk if needed.
  • Greek yogurt – Yogurt in waffles is a fantastic addition that enhances the texture and flavor. I typically use my Instant Pot Greek yogurt. It adds moisture, tenderness, and a slight tanginess to the waffles. You can also make quark waffles by substituting the yogurt with quark 1:1.
  • Butter – Unsalted butter works best but you can also use salted butter or substitute it with 1/4 cup of coconut oil as a plant-based option.
  • Egg – A large egg in waffle batter provides binding, moisture, leavening, and flavor.
  • Flour – All-purpose flour works best but you can also use whole wheat flour or substitute 1/3 of the flour with oat flour for a more wholesome flavor.
  • Baking powder – It acts as a leavening agent and gives the waffles their fluffy texture.
  • Maple syrup – The syrup adds a subtle sweetness to the waffles. You can add more if you prefer sweeter waffles or substitute it with sugar or honey.
  • Vanilla – Vanilla extract adds richness and flavor. You can also use vanilla syrup or essence if needed.

Variations

  1. Extra protein: Add a scoop or two of your favorite protein powder to the waffles batter to boost the protein content. Vanilla or chocolate whey protein powder work well.
  2. Chocolate waffles: Add 2 tbsp of cocoa powder and some chocolate chips to the batter for a chocolatey twist. Serve with a drizzle of chocolate sauce.
  3. Spice it up: Mix in 1 tsp of pumpkin spice or Christmas spice mix to the batter for warm and aromatic waffles. Top with a dusting of cinnamon and icing sugar.
  4. Go nuts: Add 2 tbsp of peanut butter or almond butter to the batter for a nutty waffle flavor.
