- Blend all ingredients (except the cacao nibs to fold in, if using) together in a blender until smooth.
- Pour mixture into popsicle molds. If using cacao nibs, fill molds 1/3 at a time and layer in about ¼ teaspoon of cacao nibs after each third. Once molds are filled, give the mixture in each mold a little swirl with a straw or spoon handle to distribute the nibs.
- Freeze for at least 4 hours or until frozen solid. Run outside of mold under a bit of hot water to loosen and remove popsicles.
