Pour the premade baked beans and their sauce into a casserole dish or crockpot.
Drain the great northern beans and add the beans to the casserole or crockpot.
Add 1 Tablespoon each Worcestershire sauce and mustard, 2-3 Tablespoons ketchup and 1 teaspoon each garlic powder and onion powder.
Mix all and bake at 300 for 30 minutes or heat in the slow cooker for 3-4 hours. If you double the recipe you can use 1 can of black beans to replace the second can of great northern beans. Or pinto beans instead of either.
