Temperature of the Sweet Potato Matters

Ensure your sweet potato is fully cooled or refrigerated before blending. Using cold potato helps the batter maintain a thicker consistency, which leads to a fluffier waffle.

Flexible Toppings!

These pair perfectly with a dollop of Greek yogurt (for extra probiotics), a drizzle of drippy peanut butter, and sliced bananas for a complete 10/10 breakfast experience.

Let the Batter Rest: Let the batter sit for 5 minutes. While the batter rests, preheat your waffle iron. Greasing the iron well is essential for this flourless batter.
