The Ultimate Crispy Heart Waffles, Sourdough Style
Updated: Sep 22
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:
The "I need waffles now" option: Preheat and grease your waffle iron immediately. Bake and eat!
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!
Why Are My Waffles Not Crispy?
Crispy waffles depend on moisture control. If your waffles turn out soft instead of crunchy, they were likely underbaked or allowed to trap steam after baking. For the crispiest results, bake the waffles until they are deep golden brown rather than lightly colored. Transfer them immediately to a wire rack and never stack them while they are still warm, as trapped steam quickly softens the crust. A batter that contains too much liquid can also reduce crispness. Allowing the batter to ferment for several hours often improves both texture and flavor.

How to Store Crispy Heart Waffles
If you have leftovers, allow the waffles to cool completely before storing them. Place them in an airtight container at room temperature for short-term storage. While they remain enjoyable the next day, the texture will gradually soften. To restore crispness, reheat them briefly in a waffle iron, toaster, or oven until the exterior becomes crunchy again.
Can You Freeze Crispy Heart Waffles?
Yes. These sourdough heart waffles freeze surprisingly well. Allow them to cool completely, separate layers with parchment paper, and store them in a freezer-safe container. To serve, reheat directly from frozen in a toaster or hot oven. This helps restore much of their original crisp texture.
