Start by preheating your oven and spraying a muffin tin with cooking spray. Place 5–7 frozen tots in each muffin well, depending on size. Bake them until golden and slightly crisp.
Once the tots are cooked, use a small glass or measuring cup to press them down into the muffin wells. Twist slightly to form a cup shape with edges reaching near the top. This makes a perfect little vessel for your fillings.
Fill each tater tot cup with freshly shredded cheddar. I like using a small melon baller to evenly distribute the cheese. Bake briefly until the cheese is melted and gooey.
Garnish with cooked bacon bits, a dollop of sour cream, and chopped chives. You can also get creative with sauces like ranch, BBQ, or a little salsa drizzle. Serve immediately for the best texture.
