Marinate the Chicken: In a large bowl, combine the chicken cubes, buttermilk, ¼ cup / 60 ml (2 fl oz) Buffalo sauce, salt, and pepper.
Stir to coat, cover, and refrigerate for at least 30 minutes.
Prep for Baking: After the chicken has marinated for 15 minutes, preheat your oven to 450°F / 232°C.
Line a large sheet pan with parchment paper.
Set Up Breading Stations: In one shallow bowl, whisk together the almond flour and grated Parmesan.
In a second shallow bowl, beat the 2 large eggs.
Bread the Chicken: Remove a chicken cube from the marinade, allowing excess to drip off.
Dip it into the beaten egg, then press it firmly into the almond flour mixture to coat all sides.
Place the coated chicken on your prepared sheet pan.
Repeat with all remaining chicken pieces, arranging them in a single layer.
Drizzle and Bake: In a small bowl, whisk together the olive oil and 3 tablespoons (45 ml / 1.5 fl oz) of Buffalo sauce.
Drizzle this mixture evenly over the chicken.
Bake for 30 minutes, or until the coating is golden brown and the chicken is cooked through.
Make the Dip: While the chicken bakes, whisk together the mayonnaise, sour cream, the remaining 1 tablespoon (15 ml / 0.5 fl oz) of Buffalo sauce, smoked paprika, and pepper in a small bowl.
Serve Hot: Serve the crispy boneless wings immediately with the creamy Buffalo dip on the side.
