Begin by gathering all the ingredients.
Next, you'll cook the corn, on the grill, in a skillet, or over the flame of a gas stove. Toast the corn until the outer kernels are lightly charred. This will give the dip a delicious nutty flavor. Use fresh corn on the cob or frozen corn in a skillet.
When getting ready to mix the items together, reserve a small portion of corn, cheese, and cilantro to garnish the dip with.
In a medium bowl, mix the sour cream, cotija cheese, cilantro, chili powder, paprika, garlic, lime juice, onion, and jalapeno. Mix well until all combined.
If using corn on the cob, cut the corn off the cob. Then stir the cooked corn into the dip mixture.
Garnish with reserved toppings.
Serve with tortilla chips, top tacos, or tostadas.
Refrigerate or serve immediately.
