Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper.
Slice the jalapeños in half lengthwise and carefully scoop out the seeds and membranes with a spoon for milder heat. Place the prepared peppers on the baking sheet.
In a small mixing bowl, combine the softened cream cheese, shredded cheddar, buffalo sauce, smoked paprika, and lemon juice. Mix until smooth and creamy, with a slightly fluffy texture.
Using a spoon, generously fill each jalapeño half with the cheese mixture, pressing gently to pack the filling inside.
Sprinkle breadcrumbs evenly over the stuffed jalapeños, pressing lightly to help them adhere and adding a crunchy topping.
Place the baking sheet in the oven and bake for 15-20 minutes, until the cheese is bubbling and golden, and the jalapeños are slightly blistered and tender.
Remove from the oven and let rest for 5 minutes to allow the cheese to set slightly. Finish with a quick drizzle of buffalo sauce or a squeeze of lemon for extra brightness.
Serve hot with your favorite dipping sides, such as ranch or celery sticks, and enjoy the perfect balance of heat, creaminess, and smoky flavor.
