Preheat the oven to 400°F (200°C).
Line a rimmed baking sheet with parchment and lightly oil it.
In a mixing bowl, combine cream cheese, cheddar, jalapeños, bacon, green onion, garlic powder, onion powder, smoked paprika, cumin, salt, and pepper. Mix until the cream cheese is evenly distributed.
Add the ground beef and ground pork to the bowl. Sprinkle in the almond flour.
Crack in the eggs and add 1 tbsp heavy cream.
Using clean hands, mix just until combined. If the mixture feels dry or crumbly, add the remaining 1 tbsp heavy cream. If too wet, add a bit more almond flour, 1 tablespoon at a time.
The mixture should hold its shape without sticking aggressively to your hands.
With damp hands, form golf ball–sized meatballs (about 1.5 inches wide). You should get 18–22 meatballs. Place them evenly on the baking sheet.
Bake for 14–17 minutes, or until the centers reach 160°F (71°C).
They should look set and release a bit of fat onto the pan.
For color, switch to broil and cook for 1–2 minutes more, watching closely to prevent scorching. Optionally, sprinkle a little extra cheddar on top before broiling for a bubbly finish.
Rest for 5 minutes. Garnish with sliced jalapeños, chopped cilantro, or a dollop of sour cream.
Serve with a simple side: salad greens with lime vinaigrette, roasted broccoli, or cauliflower rice.
