Stir the sour cream and taco seasoning together in a bowl until the seasoning is fully mixed in.
Spoon about 1/4 cup of refried beans into the bottom of each of four clear cups and spread it into an even layer.
Add a layer of the seasoned sour cream over the beans in each cup, using about 1/4 cup per cup.
Spoon 1/4 cup of salsa on top of the sour cream layer in each cup.
Spread 1/4 cup of guacamole over the salsa in each cup.
Sprinkle 1/4 cup of shredded cheddar cheese on top of the guacamole in each cup.
Place a few sliced black olives on the cheese layer of each cup to create simple window and door shapes.
Set the cups on a tray with a bowl of tortilla chips nearby for dipping.
