Here are two very different recipes that I found for you on the internet, Bets. I have not tried either one. I hope that one of them is what you are looking for.

8 ounce cream cheese
3/4 tsp garlic powder

Mix first 4 ingredients with hand or stand mixer on medium until softened and well mixed. Add next two ingredients and mix on med-low until just incorporated. Add spinach and mix on low until just incorporated. Transfer mixture to a small ovenproof dish and sprinkling cayenne on top to taste. Top with cheddar.

Bake for 15-18 minutes or until bubbling around the edges. Remove from oven and allow to set for 5-7 minutes before serving.
