Add peanut butter, liquid sweetener, melted coconut oil, salt, and coconut flour to a food processor. Pulse until completely combined, scraping down the sides. Add more coconut flour 1 Tablespoon at a time if the mixture isn't easy to work with by hand.
Scoop 2-Tablespoon-sized scoops and mold into an egg shape. Place on a parchment-paper-lined baking sheet that will fit in your freezer. Continue shaping until all the mixture is used.
Place the baking sheet in the freezer for about 15 minutes so they're good and set up before dipping in chocolate.
In a small microwavable bowl, melt the chocolate chips and coconut oil in 30-second intervals until completely melted and smooth.
Remove the peanut butter eggs from the freezer and using a fork, dip each egg, one by one, into the chocolate, tapping any excess chocolate.
Place chocolate peanut butter eggs back on the parchment paper. If you are wanting to decorate with sprinkles, do so immediately before the chocolate hardens. Once all eggs are coated, place back in the freezer for at least 15 minutes to set.
At this point they are finished. Or you can put melted chocolate in a small ziploc bag and cut off the corner to pipe decorations on the set eggs, creating a little more dimension.
Store in an air-tight container in the refrigerator for a week and the freezer for about a month.
