Why You'll Love These Protein Blondies

• High Protein: Vanilla protein powder, Greek yogurt, egg, and egg whites help boost the protein content to support muscle recovery, satiety, and your daily protein goals.
• Soft and moist: Unsweetened applesauce and Greek yogurt add moisture without needing a large amount of oil or butter, keeping them low fat
• Made with simple ingredients: You only need a handful of pantry staples and a few minutes to prepare the batter.
• Gluten-free adaptable: Oat flour makes these blondies naturally wheat-free. If you have celiac disease, be sure to use certified gluten-free oats and oat flour, or an easy substitution is almond or rice flour.
• Lower in added sugar than many traditional blondies: Applesauce provides natural sweetness, while a small amount of maple syrup adds that classic cookie flavor. The recipe still contains some added sugar, but you can adjust it to your taste.
• Packed with cozy cinnamon flavor: Cinnamon gives these blondies their signature snickerdoodle taste, with a little cinnamon-sugar topping to finish them off.

Pro Tip: Protein powder brands vary in sweetness, texture, and how much liquid they absorb. Start with the recipe below, then add a splash of milk if your batter seems too thick. You want a thick, spreadable batter rather than a dry dough.
