Creamy peanut butter, gooey chocolate, and crunchy cereal are an INCREDIBLE trio in these soft and chewy rice krispie chocolate chip cookies! Easy to whip up in only 20 minutes with a handful of ingredients.
Preheat oven to 350F. Line two large baking sheets with parchment paper and set aside.
In the bowl of a stand mixer OR with a handheld electric mixer, beat butter and sugars together until completely creamy, about 1-2 minutes. Beat in peanut butter, egg, and vanilla until smooth.
In a medium bowl, combine flour, baking soda, cinnamon, and salt. Mix flour mixture into butter mixture until a soft dough forms. Fold in rice krispie cereal and chocolate chips.
Scoop dough into 1-in balls and place 1-in apart on prepared baking sheets. Bake cookies at 350F 9 minutes, then remove from oven and tap pan on counter several times to flatten cookies. Return cookies to oven for an additional 3-4 minutes or until edges are lightly browned.
Top cookies with a sprinkle of sea salt if desired. Cool cookies on pan 10 minutes then transfer to a wire cooling rack to cool completely. Enjoy!
