The Ultimate Crispy Heart Waffles, Sourdough Style

Are you ready to leave soft, spongy waffles behind and go all‑in on crunch? These crispy heart waffles, sourdough style, are thin, golden, and delightfully brittle, very different from the fluffy breakfast waffles you may know. Think crisp edges, a light snap when you bite in, and that classic heart‑shaped pattern that feels instantly nostalgic. If you’re looking for something quick and airy, you might prefer our sourdough waffles recipe for soft, same‑day baking. But when texture is the goal, these hard waffles are in a league of their own.

What makes them extra special is the optional use of sourdough starter or discard. A small amount adds a subtle, complex tang that balances sweetness and turns these waffles into something far more interesting than a simple treat. They’re also a perfect way to put leftover starter to use, fast, low-waste, and incredibly satisfying. If you keep a discard jar in your fridge, you’ll find plenty more inspiration in our collection of sourdough starter discard recipes, where crisp, creative bakes go far beyond bread.

Instructions for Crispy Sourdough Heart Waffles

These step‑by‑step instructions guide you through making thin, crunchy heart waffles, from mixing the batter to baking them crisp in a heart‑shaped waffle iron.

Step 1: Mixing

Melt your butter (100g or 7 Tbsp) and then combine ALL the ingredients in one bowl. Stir until just combined.

Step 2: Time vs. Taste

You have two paths:

1. The "I need waffles now" option: Preheat and grease your waffle iron immediately. Bake and eat!

2. The "I Seek Flavor Depth" Path (Recommended): Cover your bowl with a damp cloth (to prevent crusting) and wait at room temperature for 4 to 24 hours. This gives your starter a chance to work its magic and develop that classic sourdough flavour.

Step 3: Baking the waffles

Preheat your waffle iron until it's hot. Grease it with a little butter. Scoop in the batter and spread it across the waffle iron. The waffles will rise during baking. Press the waffle iron firmly at the start, then let it bake without forcing it. Bake until they are deep golden brown and look crunchy! Pale waffles are soft waffles.

Step 4: The Immediate Rack Transfer

The secret to a lasting crisp? Cool them down immediately on a wire rack. Do not stack the waffles, because stacked waffles trap steam and lose their crisp texture.

Step 5: Time to enjoy

Eat them while they are still slightly warm! But be warned: The major downside to this recipe is that when they are warm, they are so dangerously delicious that you will inevitably realize you didn't make nearly enough batter. You've been warned! Enjoy your tasty waffles!
