01 - Preheat the oven to 400°F and line a baking sheet with parchment paper.
02 - Slice jalapeños in half lengthwise. Carefully remove seeds and membranes; wearing gloves is recommended for safety.
03 - In a medium bowl, mix cream cheese, cheddar, spring onion, garlic, cilantro, smoked paprika, salt, and black pepper until well combined.
04 - Fill each jalapeño half generously with the cheese mixture, smoothing the top to ensure even coverage.
05 - Combine breadcrumbs with olive oil in a small bowl. Sprinkle the mixture evenly over the filled jalapeños to add a crunchy texture.
06 - Arrange the stuffed jalapeños on the prepared baking sheet. Bake for 18–20 minutes, or until the filling is bubbly and breadcrumbs are golden.
07 - Allow the poppers to cool for 5 minutes before serving to ensure the filling sets properly.
