Combine walnuts, dates, oats, & coconut oil into a food processor.
Process the crust mixture until a dough forms.
Place even amounts of the dough into muffin cups or a muffin pan.
Press the crust/dough mixture down and compact it into the bottom of the muffin cups in an even layer.
Place the muffin cups into the refrigerator to chill.
Next, add the coconut cream, powdered sugar, lemon extract, and optional food coloring to a mixing bowl.
Beat the cream mixture until combined and creamy.
Remove the muffin cups from the refrigerator and scoop the cream mixture into the muffin cups evenly.
If you want, you can add walnuts, coconuts, or both to the top of the muffin cups.
Place the muffin cups back into the refrigerator to chill for at least 1 hour (preferably overnight).
Keep the desserts in the refrigerator until ready to serve.
Store leftovers in the refrigerator in an air tight container.
