Healthy desserts don’t have to mean no sugar and…well, no fun! Plus, I have a thing for creating recipes like this that taste way too good to be healthy. They’re refined sugar free, yet they are freaking DELISH. I can almost guarantee you’ll be coming back for more until the tray is empty. Consider this your warning to double the batch. 😉

How to make these Chewy Oat & Peanut Butter Cookie Bars

  • When choosing your peanut butter, get the good stuff – Opt for ‘natural’ with no added sugar or oils. Peanut butter not only acts as a natural oil in this recipe, but also flour and keeps the health game in check! Seriously… What can’t peanut butter do?
  • Serving options – Perfect to enjoy as is, as a midday snack, or as a late night dessert after dinner with a side of vanilla bean coconut ice cream.
  • Meal prep friendly – These cookie bars are perfect for meal prep. The recipe makes 9 squares which will store nicely in an airtight container at room temperature for 3-5 days.

Like most of my recipes, these Chewy Oat & Peanut Butter Cookie Bars are super easy to make and only require 10 ingredients! You can make these cookie bars with your little one on your hip or in a baby carrier. They are such a fun treat for a dessert or even just a late night snack!

Refined Sugar Free Cookie Bars

Peanut butter mixed with natural sweeteners give your cookie bars that sweetness (and that ooey gooey texture) without adding refined sugar. I love using a combination of coconut sugar and maple syrup because it’s healthier and naturally sweet.

Instructions:

  • Preheat the oven to 350F and line a 8x8 baking pan with parchment paper.
  • Next, in a large mixing bowl, either with a stand mixer or using an electric hand mixer, whisk together the two peanut butters, coconut sugar, maple syrup, and vanilla until smooth. Crack in one egg at a time and whisk until combined.
  • Stir in the oats, baking soda and sea salt until just combined, making sure to not over mix.
  • Fold in the chocolate chips and transfer the batter to your baking pan, making sure to press the mixture down evenly with the back of a rubber spatula.
  • Bake in the oven for 18-20 minutes or until the edges are rounded and the top is slightly firm to the touch.
  • Transfer to a cooling rack and allow it to fully cool to firm up a bit before slicing, as this will ensure they are extra gooey and soft inside.
