Before anything else, I prep all the ingredients so the process feels effortless. I dice the jalapeños finely and drain the corn very well. Softened cream cheese makes a big difference, so I never skip that step.
I add the cream cheese, sour cream, corn, jalapeños, garlic powder, salt, and pepper directly into the slow cooker. Everything gets a gentle stir so the ingredients are evenly distributed before cooking begins.
I set the slow cooker on low and let it cook for about two hours. Every 30 minutes, I give it a stir to help the cream cheese melt smoothly and prevent sticking.
Once the mixture is hot and creamy, I stir in the shredded cheddar cheese. It melts quickly and thickens the dip, making it extra luscious.
Right before serving, I sprinkle chopped green onions on top. I give it one last stir, taste for seasoning, and adjust salt if needed before serving warm.
