This is basically just a 7ish layer bean dip — so you can totally customize it however you want! This is just how I made mine:
Mix together refried beans and cream cheese. Spread on the bottom of a pie pan.
Mix together sour cream and taco seasoning. Spread on top of beans.
Use prepared guacamole — or make your own — and spread that on top of the sour cream mix.
I used one of those sour cream already-in-a-squeeze-bottle contraptions and it worked great! Or you can put sour cream into a piping bag or plastic bag and snip the corner off. This is to create your spider web look!
Next, sprinkle the diced tomatoes around the outside and cut a cute little spider out of tomatoes or olives to sit in the center of the web. Serve with blue tortilla chips if you have them!
