Stir the refried beans and taco seasoning together in a mixing bowl until evenly combined.
Spread the bean mixture evenly across the bottom of an 8x8 serving dish.
Spoon the sour cream over the beans and smooth it into an even layer.
Add the guacamole as the next layer and spread it gently to cover the sour cream.
Spread the salsa over the guacamole.
Sprinkle the shredded cheddar cheese across the top to cover the salsa.
Press the rectangular crackers upright into the cheese layer to stand as tombstones.
Scatter the sliced black olives around the base of the crackers and finish with the chopped cilantro.
