Prepare the Ingredients: Gather all your ingredients and have them measured out and ready to go.
Mix Dry Ingredients: In a large mixing bowl, combine flour, sugar, baking powder, baking soda, and salt. Mix well.
Combine Wet Ingredients: In a separate bowl, whisk together sourdough discard, milk, cottage cheese, and eggs until fully combined.
Mix Wet and Dry Ingredients: Pour the wet ingredients into the bowl with the dry ingredients. Gently mix until just combined. Be careful not to overmix; it's okay if there are a few lumps.
Preheat the Skillet: Heat a waffles iron over medium heat. Lightly grease with butter or cooking spray.
Cook the Pancakes: Pour batter into sprayed waffle iron until it almost fill the waffles iron, but not all the way to the edges as it will spread when the lid is closed. Cook until the light on your waffle iron turns green.
Keep Warm: Transfer the cooked waffles to a plate and keep warm. Repeat the cooking process with the remaining batter, greasing the iron as needed.
Serve the waffles warm with your favorite toppings such as maple syrup, fresh berries, or peanut butter.
