Stir all of the ingredients together. Careful stirring in the sprinkles, as they may slightly bleed their color. The mixture will be thick. Taste it. If you want it sweeter, you can add a little more agave/honey. If you want a little more lemon, add more juice or zest. Pour mixture evenly into each popsicle mold. If your popsicle mold has slots for sticks, you can insert them before freezing - if not, freeze for 2 hours, then put a wooden popsicle stick in the middle (that is what I did). Continue to freeze for an additional 3-4 hours or overnight. Run popsicle molds under warm water to easily remove. Eat on a hot day!
