Line a 10x10-inch pan with parchment paper. Set aside.
Mix the peanut butter and the honey in a small saucepan and turn the heat on low. Heat until it is melted and combined, but do not let it boil or burn.
1½ cups creamy peanut butter, ⅔ cup honey
Remove from heat and add the coconut oil while the mix is still warm. Mix until melted.
2 tablespoons coconut oil
Add in the vanilla and combine.
1 teaspoon pure vanilla extract
Pour the mix onto the rice krispies and mix until combined. Do not overmix it so the rice cereal does not break.
4½ cups Rice Krispies cereal
Pour into the prepared pan, and use a spatula to flatten the top, so it is even.
Make the chocolate topping by adding chocolate to a microwave-safe bowl. Microwave on high in 30-second intervals, stirring in between, until chocolate is completely melted.
1 cup semisweet chocolate chips
Pour the melted chocolate over the rice and use a spatula to spread it evenly.
You may garnish with sea salt if you like and place the pan into the refrigerator.
Sea salt
After 15 minutes, take the pan out of the refrigerator and cut the rice crispy treats into squares.
Place the pan back in, and leave them in for an additional 20 minutes or until the chocolate has hardened.
