First, add all of your peanut butter rice krispie treats ingredients to a food processor MINUS the rice cereal (Medjool dates, drippy natural peanut butter, vanilla extract and salt). Process for a couple minutes until the dates are in very tiny pieces and the mixture is soft and moist and easily sticks together. If it feels a little dry, feel free to add 1 or 2 tbsp of water and process again.
Next, add your peanut butter date mixture to a microwave safe bowl and microwave for about 25 seconds. Alternatively, you can put the mixture in a small pot and heat up on the stove top. You just want the mixture warm, not hot, for mixing with the rice cereal.
Once the peanut butter date mixture is warm, add in your rice cereal and mix very very well. If the mixture still doesn’t look like it’s sticking together, you can add a tablespoon of water and keep mixing.
Line an 8 x 8 baking dish with parchment paper and add the peanut butter rice krispie treat mixture and press down very very well so that it all sticks together.
Next, add your dark chocolate chips to a microwave safe bowl or to a small pot on the stove. Melt the chocolate chips and then stir in your drippy natural peanut butter. Mix well and then add the dark chocolate peanut butter layer on top of the peanut butter rice crispy treats.
Freeze until the chocolate has set, about 10 or so minutes. Slice and enjoy! You can top with sea salt if desired. Store these Healthy Vegan Peanut Butter Cup Rice Krispie Treats covered in the fridge.
