You're going to go nuts over these Sugar Cookie Bars! Sweet, buttery, and dense, these bars pair PERFECT with creamy strawberry frosting and sprinkles. And they're lightened up, but you'd never know because they're still full of the good stuff! Truly a sweet treat everyone will enjoy.
Preheat the oven to 350 degrees F. Line a 8x8" baking dish with parchment paper and/or spray with cooking spray.
In a large bowl combine the butter, brown sugar, sweetener, and vanilla; beat with a hand mixer or whisk until smooth.
Add the egg and applesauce and beat again. Then add in the flour and protein powder and stir just until dry ingredients are incorporated.
Pour batter into the prepared pan and even out so the top is smooth.
Bake for 25-30 minutes or until the center is set.
Let the blondies cool to room temperature then place in the fridge for an hour or until ready to frost.
When ready, spread the frosting evenly over the bars and top with sprinkles, if desired. Cut into bars and enjoy!
