For best results, ensure the cream cheese is fully softened to avoid lumps in the filling. Chilling the mixing bowl and beaters before whipping the cream helps achieve stiff peaks more quickly. If you don't have silicone ice cube trays, you can use mini muffin tins lined with parchment paper liners. Feel free to experiment with different flavors of jelly or chocolate drizzles to customize your cheesecake bites.
