Heat the oven to 400°F.
In a medium bowl, stir together the cooked chicken, cottage cheese (blend it first if you prefer a smoother dip), 1 cup of the cheddar, the hot sauce and the garlic powder.
Mix everything well, then move it to a small casserole dish or any other oven-safe dish.
Level the surface and top with the remaining 1/4 cup of cheddar, or a little more if you like.
Bake in the preheated oven for 15 to 20 minutes, until bubbling.
For a browned, crisp top, switch on the broiler for the final 1 to 2 minutes, watching closely so it doesn't burn.
Remove the dip from the oven, let it cool for a few minutes, then serve with fresh veggie sticks or tortilla chips.
