Get Ready: Start by preheating your mini or classic style waffle iron. Avoid using a deep Belgian style waffle maker for this recipe.
Whip Egg Whites: In a large bowl, beat the egg whites along with the salt and cream of tartar until they form stiff, glossy peaks. Set aside.
Combine Dry Ingredients: In a separate large bowl, whisk together the almond flour, erythritol sweetener, and baking powder until well combined.
Mix Wet Ingredients: To the dry mixture, stir in the room temperature almond milk, the egg yolk (from your separated egg), avocado oil, and vanilla extract. Mix until the batter is smooth and lump-free.
Fold Gently: Carefully and gently fold the beaten egg whites into the almond flour mixture. Continue folding until no white streaks remain, keeping the batter light and airy.
Cook Waffles: Lightly grease your preheated waffle iron. Spoon about 3 to 4 tablespoons of batter into each mini waffle well or section. Close the lid and let them cook without disturbing for 4 to 5 minutes, then gently lift to check for a golden brown color.
Cool & Repeat: Transfer the cooked waffles to a wire rack placed over a rimmed baking sheet. Re-grease the waffle iron lightly before cooking the rest of the batter. For an extra crispy finish, you can place the baking tray of waffles in a 200°F (95°C) oven for 10-15 minutes after cooking.
Prepare Coating: In a shallow bowl, mix together the granular sweetener and cinnamon for your irresistible "churro" coating.
Coat Waffles: While the waffles are still warm, lightly brush each side with melted butter, then immediately dip them into the cinnamon mixture, ensuring an even and delicious coating.
