INGREDIENTS

  • Light butter – I used I Can’t Believe It’s Not Butter Light.
  • Brown sugar – This helps create the ‘chewy cookie” effect. I used Swerve brown sugar. You can use brown sugar, coconut sugar, or other brown sugar sweetener alternative of your choice.
  • Sweetener – I used Swerve granular sweetener.
  • Vanilla extract
  • Egg
  • Unsweetened applesauce
  • Flour – I used all-purpose flour. This white flour helps create the best sugar cookie texture. You could replace with Bob’s 1:1 gluten-free flour to make gluten-free if necessary.
  • Protein powder – I used PEScience Gourmet Vanilla. Cake Pop or a birthday cake flavor would also work great. Not all protein powders bake the same, so if you use another brand, just make sure it is also a whey + casein blend and one that bakes well.

  • Frosting – I used whipped strawberry! Use whatever kind sounds good.
  • Sprinkles – Get creative here! You can use these to make these bars more festive around the holidays!

HOW TO MAKE SUGAR COOKIE BARS

  1. Preheat the oven to 350°F. Line a 8×8″ baking dish with parchment paper and/or spray with nonstick cooking spray.
  2. In a large bowl, combine the butter, brown sugar, sweetener, and vanilla. Beat with a hand mixer or whisk until smooth. Add the egg, applesauce, and molasses and beat again. Then, add in the flour and protein powder. Stir just until combined. 
  3. Pour batter into the prepared pan and even out so the top is smooth. Place the pan in the oven and bake for 25-30 minutes or until the center is set. 
  4. Let the blondies cool to room temperature. Then, place them in the fridge for an hour or until ready to frost. 
  5. Spread the frosting evenly over the bars and top with sprinkles, if desired. Cut into bars and enjoy! 

STORAGE TIPS

These are best eaten chilled the next day! Keeping them in the fridge overnight allows them to get to the desired temperature and allows the flavors to come together. Store the bars in an airtight container in the fridge (frosted or not frosted) for up to a week.

To freeze, hold off on frosting. You’ll want to wait until you’re ready to eat as the frosting won’t hold up well when you defrost the bars. Wrap bars individually and store in an airtight Ziplock bag in the freezer for 3 months.

FREQUENTLY ASKED QUESTIONS

What’s the difference between cookies and cookie bars?

Cookie bars are made by pressing batter into a pan whereas cookies are made from individual pieces of dough. Technically, any cookie could be made into a cookie bar. Bars are typically a little more dense and chewy.

Do I need to use strawberry frosting?

Not at all! Feel free to use your favorite. Chocolate, vanilla, or another flavor would work great.

How do you recommend I serve these bars?

I think these bars taste best chilled and eaten the next day. Storing them overnight allows the flavors to come together a little more!

  1. As soon as I saw these were posted I couldn’t wait and made them last night. Holy moly!! The whole house loved them and you still can’t convince me these are lightened up! Great recipe 😊

  2. Is the frosting just generic store bought frosting? I didn’t see a recipe for the frosting or any mention of brand. And is it included in the macros, or at the macros just for the bar, without frosting? Thanks!
