    ½ cup light brown sugar, 1 cup natural peanut butter, 2 teaspoons vanilla extract
  • Add in the flour, oats, salt, and baking soda. The dough will be very thick and clumpy, but it should hold together if you squeeze a handful of it.
    1 cup white whole wheat flour, 1 cup rolled oats, 1 teaspoon baking soda, ¼ teaspoon salt
  • Slowly add the milk in a steady stream, mixing until a clumpy dough forms.
    ½ cup milk
  • Fold in chocolate chunks, using your hands to knead everything together.
    ¾ cup dark chocolate chips or chunks
  • Press the dough into the prepared baking dish - wet hands are helpful here
  • Bake for about 15-20 minutes until the bars are lightly golden on top and set.
  • Allow to cool completely and cut into squares.
  • Once cooled, drizzle with melted dark chocolate if desired.

Notes

  • Nutrition values are an estimate only.
  • Can I use an alternate sweetener in these oat bars? I've made these using an equal amount of coconut sugar and they turned out just fine, if only a smidge more crumbly.
  • Are these oat bars vegan? If you use a plant-based milk and vegan chocolate, they're totes vegan.
  • Can these oat bars be made gluten-free? I personally haven't tried this as I always use whole wheat flour, but I'm willing to bet they can be made with a gluten-free flour blend instead. Also be sure to seek out gluten-free oats if it's important for you.
  • How should I store these oat bars? They'll last about a week in an airtight container at room temperature. 
  • Can I freeze these oat bars? Please do! They'll last about 3 months in the freezer.
  • Can I use something else in place of the chocolate? I've made these with half chocolate half raisins before and they're super tasty.
