Why You'll Love It

These spicy chaffles prove that eating keto can still be fun, flavorful, and satisfying.

Ingredients & Substitutions

You only need a few simple staples to make these spicy chaffles — plus a couple of easy swaps if you’d like to adjust the flavor or heat level.

Egg – The essential binder that holds everything together. One large egg is all you need for 2 mini chaffles. If you want a fluffier texture, you can separate the egg and whip the white before folding it back in.

Mozzarella cheese – Melts smoothly and crisps up perfectly in the waffle maker. For a stronger flavor, try cheddar, pepper jack, or even a Mexican blend. Pre-shredded cheese works in a pinch, but freshly grated melts better.

Cayenne pepper – The original source of spice in this recipe. Just a pinch gives a warm, lingering heat without overpowering. Adjust the amount to suit your spice tolerance.

Garlic powder – Rounds out the flavor with a savory backbone. Onion powder can be used instead if you want something milder and slightly sweet.

Jalapeño (optional substitution) – If you’d like more texture and freshness, swap or add finely diced jalapeños. Use fresh for bold flavor or pickled for a tangy twist. Remove seeds for less heat.

How to Make It

With just a few quick steps, you’ll have crispy, cheesy chaffles ready in under 10 minutes:

Heat It Up

Preheat your mini waffle maker until it’s nice and hot. This guarantees crispy edges every time. Don’t have one yet? I use this mini waffle maker — it’s affordable and perfect for keto chaffles.

Whisk the Egg

Crack the egg into a small bowl and whisk until smooth. This helps give your chaffle the right structure.

Add the Good Stuff

Mix in the shredded mozzarella, cayenne pepper, and garlic powder until everything is evenly combined.

Press & Sizzle

Spray the waffle maker lightly with avocado oil spray (it holds up well to high heat). Then sprinkle a pinch of cheese directly on the hot surface before pouring in half the batter. This creates a golden, crispy coating. Close the lid again and cook for 3–4 minutes until golden and crisp.
Tip: For extra crispy sides, sprinkle a little cheese on the waffle maker before adding the batter and again halfway through cooking. This coats both sides in golden, cheesy crunch.

Double the Fun

Carefully remove your first chaffle and set it aside (if you can resist eating it right away!). Spray the waffle maker again, add a sprinkle of cheese if you’d like those crispy edges, and repeat the steps to make your second chaffle.
Tip: Place your chaffles on a wire rack for a few minutes after cooking — this helps the steam escape and keeps them extra crispy.

Serve & Enjoy

Stack your chaffles while they’re warm and crispy. Garnish with extra jalapeño slices if you like the heat turned up, or pair them with your favorite keto toppings. They’re perfect on their own, or you can use them as a bun for burgers and sandwiches.
