Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
Slice the jalapeño peppers in half lengthwise and use a small spoon to carefully scrape out the seeds and white membranes.
Heat the olive oil in a skillet over medium-high heat and add the ground turkey, breaking it up with a spatula.
Season the turkey with sea salt, black pepper, garlic powder, and onion powder, cooking until it is fully browned and cooked through.
In a medium mixing bowl, combine the cooked turkey, cream cheese, and half of the shredded cheddar cheese until well incorporated.
Spoon the turkey and cheese mixture into each jalapeño half, pressing down slightly to pack the filling.
Sprinkle the remaining cheddar cheese and the almond flour evenly over the top of each stuffed pepper.
Place the poppers on the prepared baking sheet and bake for 15 to 18 minutes until the peppers are tender and the tops are bubbling and golden.
