Preheat your oven to 375°F (190°C).
In a small bowl, mix together garlic powder, smoked paprika, cumin, salt, and pepper. Rub this seasoning mixture all over both sides of the chicken breasts.
Heat olive oil in a large oven-safe skillet over medium-high heat. Once hot, add the seasoned chicken breasts and cook for about 3–4 minutes on each side until nicely browned.
Remove the chicken from the skillet and set it aside. Lower the heat to medium and add butter to the same skillet. Once melted, stir in minced garlic and sliced jalapeños. Sauté for about 1–2 minutes until fragrant.
Stir in softened cream cheese and sour cream until smooth; then pour in chicken broth while continuing to stir until everything combines into a creamy sauce.
Return the seared chicken breasts back into the skillet, nestling them into the sauce.
Sprinkle shredded cheddar cheese generously over both chicken and sauce before transferring the skillet to your preheated oven.
Bake for about 15–20 minutes or until the chicken is fully cooked through and bubbly with melted cheese on top.
Garnish with fresh cilantro and serve with lime wedges on the side.
