• 4 tablespoons monk fruit sweetener
• 4 teaspoons unsweetened vanilla extract

Instructions

1. Directions
2. Preheat your waffle iron to a medium-high setting according to the manufacturer’s .
3. In a large mixing bowl, combine the eggs, shredded mozzarella, peanut butter, monk fruit sweetener, and vanilla extract. Use an electric mixer on medium speed to beat the until the batter is completely smooth and uniform.
4. Once preheated, lightly grease the waffle iron if necessary. Pour approximately one-fourth of the batter onto the center of the iron, spreading it slightly. Close the lid and cook for 4-6 minutes, or until the chaffle is golden brown and steam is no longer escaping.
5. Carefully remove the finished chaffle with a silicone spatula and transfer it to a wire cooling rack. This allows it to crisp up perfectly. Repeat the process with the remaining batter to make a total of four chaffles.
6. Let the chaffles rest on the rack for a minute or two to achieve maximum crispiness before serving warm.

Pro Tips

• For the crispiest chaffles, let them cool on a wire rack for a minute or two after cooking. Placing them directly on a plate will trap steam and make them soft.
• Don’t overfill the waffle iron. This batter expands, so using slightly less than you think you need helps prevent messy overflow and ensures even cooking.
• Using room temperature eggs is crucial. They emulsify better into the batter, creating a smoother, more uniform texture without having to over-mix.
• For the best melt and flavor, shred your own low-moisture, whole-milk mozzarella from a block. Pre-shredded cheeses often contain anti-caking agents that can affect the texture.
