Peanut Butter and Jelly Blondies

These Peanut Butter and Jelly Blondies are the absolute best combination of salty peanut butter and sweet jelly in a dense, chewy, moist blondie. Even better, they're super easy to make and less than 100 calories per bar. I guarantee you're going to be fighting your kiddos off for the last one of these!

Ingredients

  • 1/2 cup vanilla or peanut butter cookie protein powder (62g) I used PEScience
  • 3/4 cup all-purpose flour (90g)
  • 1/4 granular sweetener alternative (48g) I used Swerve
  • 2 Tbsp brown sugar alternative (24g) I used Swerve
  • 1/2 tsp baking powder
  • 1/4 tsp baking soda
  • 1/2 cup plain nonfat Greek yogurt (112g)
  • 1/2 cup unsweetened applesauce (122g)
  • 1 Tbsp pure vanilla extract
  • 2 Tbsp light butter (28g) softened
  • 2 Tbsp peanut butter chips (30g) melted
  • 2 Tbsp drippy peanut butter* (28g)
  • 3 Tbsp grape jelly (57g) or other jelly of choice (57g)

Instructions

    Cup of Yum
  1. Preheat the oven to 325 degrees F. Line a 8x8-inch baking dish with parchment paper and/or spray with nonstick cooking spray.
  2. In a large bowl, add the protein powder, flour, sweetener, brown sugar, baking powder, and baking soda. Stir dry ingredients until they are mixed well. Then add the yogurt, applesauce, vanilla, butter, and melted peanut butter chips. Using a hand mixer (or a stand mixer), mix to combine. Pour the batter into the prepared dish and spread evenly out.
  3. Drizzle the peanut butter across the blondies and add the jelly in small dollops across the top. Use a toothpick or a butter knife to make swirls. You can swirl as much or as little as you would like!
  4. Place the blondies in the over and bake for 25-30 minutes, or until a toothpick inserted in the center comes out mostly clean. It's okay if they are still a little gooey. They will set more in the pan and especially overnight.

Notes

  • These blondies are best the next day, chilled, after the texture has set and the flavors have come together overnight. Keep stored in an airtight container in the fridge.
  • *I used American Dream White Chocolate Pretzel Peanut Butter. You can use LaurenFitFoodie for 10% off your purchase.
  • To make gluten-free: I recommend using Bob's Red Mill 1:1 Gluten-Free Baking Flour or oat flour.
  • To make vegan: use vegan protein powder, vegan butter, and vegan yogurt. Replace peanut butter chips with peanut butter (gram for gram).
