Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 10 inch round cake pan or springform pan.
In a large saucepan over medium-high heat, mix black beans, pinto beans, refried beans, olives, corn, bell pepper, and jalapeno pepper. Season with cumin, chili power, and black pepper. Cook and stir until thickened, about 10 minutes.
Lay one tortilla flat on the bottom of the prepared baking pan.
Spread 1/4 of the bean mixture on the tortilla.
Sprinkle 1/4 cup Cheddar cheese lightly over the bean mixture. Repeat layering, ending with a tortilla. Top with remaining Cheddar cheese.
Bake 20 minutes in the preheated oven. Allow to cool slightly before serving.
