Have you ever craved a warm, crispy piece of bread but didn’t want all the carbs that come with it? Or maybe you’ve been looking for a gluten-free, keto-friendly alternative that still feels like real bread? These Sour Bread Chaffles are about to become your new obsession! Light, slightly tangy, and perfectly golden, they’re an easy and delicious way to enjoy sandwiches, toast, or breakfast melts without missing traditional bread.
This recipe is perfect for anyone on a low-carb, keto, or gluten-free diet, or simply looking for a healthier, protein-packed alternative. I love making a big batch ahead of time and freezing them — they reheat beautifully in the toaster and taste just as fresh as the first day!

Ingredients:
4 egg whites
4 tablespoons sour cream
½ teaspoon baking powder
6 tablespoons almond flour
1 cup shredded mozzarella cheese
Salt, pepper, or onion powder (optional, to taste)
Instructions:
- Preheat your waffle maker.
Start by turning on your waffle maker and letting it heat up. A hot waffle iron ensures your chaffles get that crisp, golden texture on the outside while staying fluffy inside. - Prepare the batter.
In a medium-sized mixing bowl, whisk the egg whites until slightly frothy. Add in the sour cream and whisk again until well combined — this gives your chaffles a light, tangy flavor and fluffy texture. - Add the dry ingredients.
Mix in the almond flour and baking powder. Stir until you get a smooth, slightly thick batter. If you like, season the mixture with a pinch of salt, pepper, or even onion powder for extra flavor. - Fold in the cheese.
Add the shredded mozzarella and mix until evenly distributed throughout the batter. The cheese is what gives these chaffles their crisp edges and bread-like texture once cooked. - Cook the chaffles.
Lightly grease your waffle maker with a touch of oil or nonstick spray. Pour in enough batter to cover the surface (about ¼ cup for a small waffle maker). Close the lid and cook for 4–6 minutes, or until golden brown and crisp. - Cool slightly before serving.
Let the chaffles rest for 1–2 minutes after cooking — this helps them firm up and makes them easier to handle. - Enjoy or store for later!
Serve immediately as sandwich bread, burger buns, or breakfast toast. To store, let them cool completely, then freeze in a ziplock bag. When ready to eat, simply pop one in the toaster — it crisps up perfectly every time!

Tips & Variations:
For a more tangy flavor, add a teaspoon of apple cider vinegar or Greek yogurt.
For extra fiber, mix in a teaspoon of ground flaxseed or chia seeds.
To make them sweet, skip the seasonings and add a touch of vanilla extract and a keto sweetener instead.
Serving Ideas:
Top with avocado and poached eggs for a hearty breakfast.
Use them as mini sandwich buns with turkey, lettuce, and cheese.
Enjoy them toasted with butter and garlic as a quick side for soups.
