How to Make It
Combine half of the chocolate chips and 1 tablespoon of the coconut oil in a microwavable bowl; microwave, stirring every 20 to 30 seconds until smooth, about 1 to 1 1/2 minutes total. Divide chocolate mixture among 16 molds of the ice cube tray. Use a small brush or the end of a knife to spread mixture evenly in each mold. Freeze 3 minutes.
Divide peanut butter (and/or raspberries, rice cereal, caramel) among chocolate cube bases. Repeat process of melting remaining chips and oil; pour over each filling. Freeze 20 minutes. Release treats from ice tray, and enjoy. Store in a plastic bag or container in refrigerator up to 5 days.
