Start by greasing your 9x9 inch baking dish with a little coconut oil or lining it with parchment paper. This will ensure that your treats come out easily once they're set.
In a microwave-safe bowl or a saucepan over low heat, combine the peanut butter, coconut oil, and keto maple syrup. Heat gently until everything is melted and combined, stirring frequently to avoid burning. This should take about 1-2 minutes in the microwave or a few minutes on the stovetop.
Once melted, remove the bowl from heat and add the keto crispy cereal to the mixture. Stir gently but thoroughly until every piece of cereal is coated in the peanut butter mixture.
Transfer the mixture into your prepared baking dish. Using a spatula or your hands (dampening them slightly can help), press the mixture down firmly and evenly. This step is crucial for ensuring that your treats hold together once set.
Refrigerate the dish for at least 30 minutes to allow the treats to firm up. This cooling time helps the ingredients bind together for that perfect chewy texture.
Once set, remove the treats from the dish (if using parchment paper) and slice them into squares or rectangles. Serve immediately or store in an airtight container for later enjoyment.
