    These Vegan Chocolate Peanut Butter Bars are fudgy and chewy, perfectly salty-sweet and covered with a thick layer of silky peanut butter-infused chocolate! They're melt-in-your-mouth rich, super satisfying, and high in protein and fibre. They're quick and easy to make, require just 4 ingredients, take 20 minutes to make and come together in one bowl. They're also gluten-free and refined sugar free and great for meal prep. They're perfect for sharing, are a great make-ahead dessert for entertaining and make excellent edible gifts!

      I love your recipes they’re great and easy to make. But just wanted to make sure on something here just to sure I’m not wrong, the nutrition facts on calories is per serving right? So in this recipe 1 bar = 347 calories. If I’m wrong please correct me thank you.

      These bars look like the peanut butter bars I enjoyed for dessert at lunchtime in my middle school cafeteria. I’ve been hoping to find a recipe for them, for years now. Thank you.
      {One issue with your wording, though: usually if I see “nut-free” in a recipe, I think of tree nuts, from raising my nut-allergic son. Peanut allergy is different—sometimes I think it’s worse for those people, like a more vicious allergy—but your suggestion of sunflower butter works for both allergies.}
