Why we love this recipe

  • The combination of chocolate and peanut butter is a classic and always a popular flavor pairing.
  • This recipe is easy to make and offers a perfect balance of sweetness and texture.
  • These yummy snack bars are naturally gluten-free and can easily be made vegan. Bonus!

Ingredients 

  • butter or coconut oil – we love using salted butter as it adds a lovely sweet and salty element to these bars. Coconut oil also works well for a dairy-free version. Be sure to use refined coconut oil and not liquid coconut oil as it needs to return to solid when refrigerated to hold the bars together.
  • coconut sugar – we prefer coconut sugar as it is less refined and has a delicious caramely taste. You could substitute brown sugar instead.
  • vanilla extract – adds that classic sweetness.
  • oats – you can use quick oats or old-fashioned oats. Both will work in this recipe. Be sure to check for a certified gluten free label if there are allergy concerns.
  • cinnamon – adds a lovely warm flavor.
  • sea salt – always add a pinch of salt to bring out all of the flavors in your recipe.
  • chocolate chips – we like to use dark chocolate.
  • peanut butter – we recommend using a natural nut butter that only lists peanuts on the label. Smooth or crunchy both work but we prefer crunchy to add some texture with the small pieces of peanuts.

Equipment

  • medium saucepan – you will need two saucepans for this recipe. One for the oat mixture and one for the chocolate peanut butter blend.
  • rubber spatula – we use this for stirring and for pressing the oat mixture into the pan.
  • baking dish – we use an 8×8 square pan for this recipe.
  • parchment paper – a must for easy cleanup! We recommend using unbleached parchment paper.

Expert tip

Use high-quality chocolate and natural peanut butter for the best flavor and texture. Avoid using peanut butter with added sugars or oils, as it may affect the overall taste and consistency of the bars.
