Delicious buttery marshmallowy thick peanut butter chocolate chip rice krispie treats. These homemade rice krispie treats are a fun flavor twist on a classic sweet treat!
Prepare a 9x13" pan by lining the pan with parchment paper and spraying with nonstick spray.
In a microwave safe bowl, melt marshmallows, butter, and peanut butter down in 30 second increments until fluid. Mix in the vanilla extract afterwards.You can also do this on the stovetop in a nonstick pan over low medium heat.
Mix together with a silicone spatula until the marshmallow peanut butter mixture becomes smooth and uniform.
Add in rice krispies cereal and mix until all combined working a bit quicker to avoid the marshmallow from setting. Quickly, fold in the semi sweet mini chocolate chips. They will slightly melt from the heat and create chocolate swirls throughout! Avoid overmixing.
Working quickly, gently pour out the rice krispie mixture spreading evenly in the prepared 9x13" pan. Be careful NOT to press and pack them down too firmly as this can dry out your rice krispies.
Let the rice krispies sit in the pan to firm up for at least 10 minutes before cutting into them. When they are set, slice evenly into 20 rectangle pieces or whatever size you desire. Store at room temperature, wrapped in saran wrap to avoid drying out.
