The combination of chocolate and peanut butter together is an absolute classic and Reese’s peanut butter cups are proof that this is a winning combination! This recipe produces bars that taste just like peanut butter cups but in bar form and completely dairy free.

They are so addicting and delicious – you’ll love them!

These chocolate peanut butter bars are the perfect sweet snack for all occasions and are a great idea to bring to any gatherings such as birthdays, work morning teas or BBQs.

The best part is that you really only need 10 minutes to throw these together and then they can just chill in the fridge until you need them making them a great option to make in advance.

Key Ingredients

You just need 5 ingredients to make these vegan bars and you may already have them all in your pantry ready to go!

all ingredients needed to make vegan peanut butter bars laid out in small bowls.

Note all ingredients and their quantities are laid out in the recipe card at the bottom of this post.

  • Dairy free butter – I always use Nuttelex buttery to replace butter in my recipes as I find it gives the best taste, but any vegan butter alternative will work.
  • Biscuit crumbs – traditionally peanut butter bars use graham cracker crumbs however in Australia and the UK a great alternative is the original Digestive biscuits as they also happen to be vegan, however you can use any plain, sweet biscuit you prefer. Simply pulse the biscuits in the food processor to create the crumbs to use in this recipe.
  • Icing sugar – for sweetness in the filling. Make sure to sift before using so it can be evenly combined.
  • Peanut butter – I’m using regular, Bega peanut butter for this recipe. I don’t recommend using a natural peanut butter as it will alter the texture.
  • Vegan chocolate – you can use vegan chocolate chips but I prefer to use a block of dark chocolate for the best flavour. Use what you like to eat.

Step-By-Step Instructions

You don’t need any special equipment to make these peanut butter bars making them the perfect beginner recipe.

You’ll need a couple of bowls and a square tin or dish that’s been lined with baking paper which will help make it easier to remove the bars once set.

To start, you’ll need your biscuit crumbs, so add the digestive biscuits to a food processor and pulse until fine crumbs form.

step one and two - making the peanut butter layer.

Measure out the biscuit crumbs and add them to a large mixing bowl with the sifted icing sugar, melted dairy free butter and the peanut butter and mix together. I like to soften the peanut butter slightly in the microwave for 20 seconds first to make it easier to mix through.

Press the peanut butter mixture into the prepared pan so it’s an even layer on the base. Set aside while you make the chocolate layer.

In a microwave safe bowl, add the chopped chocolate or chocolate chips and the extra peanut butter and place in the microwave for 20 second bursts, mixing well between each with a metal spoon until the chocolate is melted.

Pour the chocolate mixture over the peanut butter layers, ensuring it’s spread into all four corners and place in the fridge to set for at least 2 hours before slicing into squares.

You can store any remaining bars in the fridge or freezer.

They’ll last a week in the fridge and even longer in the freezer making them the perfect sweet treat to make ahead of time.
