                Warm up your oven to 150°C. Line your loaf pan (23x13 cm) with parchment and grease it up a little.

                Grab your mixer (stand or hand-held) and beat egg whites with vinegar until stiff and cloud-like. This can take 10 to 15 minutes. Set this bowl aside for now.

                In a fresh bowl, whisk up the yolks with cottage cheese, salt, baking powder, both proteins, allulose, and any extra flavors you want. Everything should end up smooth — blending works too.

                Take a little bit of that yolk mix and gently fold it into the whites to loosen them up. Slowly add the rest of the yolk mix while folding — don’t beat it or you’ll lose the fluff.

                Pour your mixture into the loaf pan and even it out. If you want little rolls, pop dollops onto a parchment-lined tray or use a silicone mold. Top with sesame seeds or bagel sprinkle if you’d like.

                Bake on the middle oven rack for about 50 minutes. It’s ready when the top goes golden and a stick comes out clean.

                When baking’s done, switch off the oven and keep the bread inside for 10 more minutes. Don’t peek yet!

                Slice it up and eat while it’s warm, toasted, or let it cool for later sandwich making. Keep leftovers the way you would with any high-protein cloud loaf.
