Preheat the oven. Set your oven to 350°F (175°C) and allow it to preheat while you prepare the appetizer.
Shape the salami cups. Press individual slices of hard salami into the cavities of a mini muffin tin, gently shaping them to line the bottom and sides of each cup.
Prepare the creamy filling. In a mixing bowl, combine the softened cream cheese, spinach-artichoke dip, and garlic powder. Stir until the ingredients are evenly incorporated and the mixture is creamy.
Fill the salami cups. Spoon the prepared cream cheese mixture into each salami-lined muffin cup, distributing the filling evenly.
Bake the appetizers. Place the muffin tin in the preheated oven and bake for approximately 10 minutes, or until the filling looks warm and creamy.
Serve. Remove the muffin tin from the oven. Allow the salami cups to cool slightly so they are easier to handle, then carefully lift them out and arrange them on a serving platter.
