Sauté diced onions in hot oil in a large Dutch oven or stockpot over medium heat, about 8 minutes or until translucent.
Add minced garlic, and sauté 1 minute. Move onion mixture to the outside edges of the pan and add beef. Cook, breaking up the beef for 6 minutes or until meat is crumbled and is no longer pink. Drain, reserving 2 tablespoons drippings in Dutch oven; return beef mixture to Dutch oven.
Stir in 1 tablespoon salt, 1 tablespoons sweet chile powder, 1 tablespoon ground cumin, 2 tablespoons smoked paprika, and 2 tablespoons granulated sugar and cook 2 minutes stirring constantly to avoid the sugar burning.
Stir in baked beans, diced tomatoes, and tomato paste.
Add 3/4 cup beer and 1 cup water; simmer 20 minutes, stirring occasionally. Add remaining 3/4 cup beer and 1/2 cup water; simmer 30 minutes, stirring occasionally.
Add ground Fritos and cook 10 minutes to allow chili to thicken.
