Heat a large, deep skillet over medium-high heat and add olive oil. Add garlic and chilis to the pan and stir until fragrant, about 30 seconds, before adding in the sweet corn. Sprinkle with salt and pepper to taste and saute for 5-6 minutes, stirring frequently.
Add butter to the corn and stir until melted. Check for seasoning and adjust accordingly. Garnish with optional toppings before serving.
