Wash your strawberries thoroughly under cold water and pat them completely dry with a paper towel. It is vital that the fruit is bone-dry because any moisture will cause the chocolate to seize or slide off. Keep the green leafy tops on as they provide a good grip for dipping.
Place the chocolate chips and coconut oil in a microwave-safe bowl. Heat in 30-second intervals, stirring well between each session, until the mixture is completely smooth and glossy. Stir in the alcohol-free vanilla extract if you are using it to add a subtle depth of flavor.
Line a baking sheet with parchment paper. Hold a strawberry by its green top and dip it into the melted chocolate until it is mostly submerged. Lift it out, let the excess chocolate drip back into the bowl, and place it gently on the parchment paper.
While the chocolate is still wet, carefully press two mini pretzels into the top sides of the strawberry to serve as antlers. You may need to hold them for a second or two to ensure they stay upright as the chocolate begins to set.
Place two candy eyes near the top of the strawberry, just below the antlers. Finish the look by placing one red candy near the tip of the strawberry to create Rudolph’s iconic red nose. Repeat this process for all remaining strawberries.
Place the baking sheet in the refrigerator for at least 15 to 20 minutes. This allows the chocolate to harden completely and ensures the decorations are securely attached before serving.
