I extended the Layered Nacho Dip from Real Housemoms by substituting the type of cheese, adding guacamole, and making smaller (and more) layers. This is a perfect way to add a non-dessert element to a science party when layering it into a beaker while still working for non-science parties if using a different serving dish. I could see this working in any glass or plastic container depending on how many layers you want while also working in an opaque dish if you don't mind the layers not being visible.
This can easily be altered based on what ingredients you prefer and how much of each you want to use.
Optionally bring the cream cheese out ahead of time to soften.
Combine the cream cheese, sour cream, and taco seasoning. Mix together until completely combined.
Shred your cheese if it isn't already.
Choose which order you want to layer your ingredients and how many layers you want it repeated. I started with the cream cheese mixture and finished with the shredded cheese. Remember to not lay the guacamole down next to an airy layer or on top if making this ahead of time as you don't want it to brown.
Chill until the cheese firms up a bit. Or keep in the fridge overnight.
Enjoy topping tortilla chips or crackers.
