In a skillet, heat the olive oil over medium heat. Add the finely chopped jalapeños and cook for about two minutes until they start to soften. Next, add the corn kernels and continue to cook for another five minutes, stirring occasionally. This step helps to release the flavors of the vegetables.
While the vegetables cool slightly, grab a large mixing bowl. Combine the softened cream cheese, sour cream, and fresh lime juice. Use a hand mixer or a whisk to beat the mixture until it is smooth, creamy, and free of any lumps. This smooth base is key to the dip's texture.
Now it's time to bring everything together. Add the sautéed corn and jalapeño mixture to the cream cheese base. Stir in the shredded cheddar cheese, chopped green onions, salt, and pepper. Mix thoroughly until all the ingredients are evenly distributed throughout the dip.
Preheat your oven to 350°F (175°C). Transfer the dip mixture into a 1.5-quart baking dish and spread it out evenly. Bake for 20-25 minutes. You'll know it's ready when the dip is bubbly around the edges and the top is a beautiful golden brown.
Carefully remove the baking dish from the oven and let it cool for a few minutes, as it will be very hot. Just before serving, sprinkle some fresh chopped cilantro over the top for a pop of color and flavor. Serve it warm for the best experience.
