1 cup sourdough discard: This leftover starter provides a unique flavor and uses up what might otherwise go to waste.
1 cup all-purpose flour: The basis of the dough, feel free to experiment with different flours for varied texture and taste.
2 tbsp sugar: Adds the essential touch of sweetness to balance the dough.
1 tsp cinnamon: The star spice that infuses these crisps with cozy warmth; adjust to your preference.
1 pinch salt: Enhances the overall flavors and cuts through the sweetness.
2 tbsp melted butter: Brushed on for a golden finish and extra richness.
Additional sugar and cinnamon to taste: For that signature cinnamon sugar sparkle on top.

How to Make Cinnamon Sugar Crisps Recipe

Step 1: Preparation

Start by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper. This ensures an even bake and an easy clean-up, setting the stage for perfect crisps.

Step 2: Mixing the Dough

In a medium bowl, combine the sourdough discard, all-purpose flour, sugar, cinnamon, and a pinch of salt. Stir until everything is evenly incorporated and a rough dough forms. This dough is forgiving and comes together quickly, making it ideal for a casual baking session.

Step 3: Rolling Out the Dough

Lightly flour your work surface and roll the dough out thinly to about 1/8 inch thickness. The thin roll is crucial; it’s what guarantees a delicate crunch once baked. Taking your time here pays off big when you bite in.

Step 4: Butter and Cinnamon Sugar Topping

Brush the rolled dough generously with melted butter — this adds moisture and helps the topping stick. Then sprinkle a generous layer of your cinnamon sugar mixture on top, making sure every section has that sweet, spicy coating.

Step 5: Cutting Into Crisps

Using a sharp knife or pizza cutter, slice the dough into small squares or rectangles. The size is up to you, but smaller pieces bake faster and provide perfect bite-sized snacks.

Step 6: Baking the Crisps

Arrange the pieces on your prepared baking sheet ensuring they don’t overlap. Bake in the preheated oven for 15-20 minutes until the crisps turn a warm golden brown. Keep an eye on them — the aroma of cinnamon sugar toasted to perfection will guide you.

Step 7: Cooling Down

Once baked, let the crisps cool completely on a rack or the baking sheet. This cooling step is essential for them to crisp up fully. When they’re ready, store them in an airtight container to keep that satisfying crunch alive.

Garnishes

A simple dusting of powdered sugar or a light drizzle of honey can elevate these Cinnamon Sugar Crisps to the next level. Fresh fruit like sliced apples or pears also adds a lovely, juicy contrast to the crisp texture and warm cinnamon notes.

Side Dishes

These crisps shine alongside creamy beverages like chai tea, hot cocoa, or a perfectly brewed latte. They also make for a surprising partner to ice cream or whipped cream, adding a crunchy texture and cinnamon sweetness that complements any dessert spread.

Creative Ways to Present

For gatherings, arrange the crisps in a layered jar or mason jar with cinnamon sticks tied around for rustic charm. You could also stack them with layers of cream cheese frosting or fruit preserves to create a playful, crunchy trifle. These treats are as visually inviting as they are tasty.

Make Ahead and Storage

Storing Leftovers

Keep any uneaten Cinnamon Sugar Crisps in an airtight container at room temperature to maintain their crispness. Stored properly, they’ll stay fresh and crunchy for up to one week — perfect for snacking throughout the week.

Freezing

You can freeze the crisps once fully cooled by wrapping them tightly in plastic wrap and placing them in a freezer bag. When stored this way, they freeze well for up to two months. Thaw at room temperature when you want a quick cinnamon sugar treat.

Reheating

If the crisps lose some of their crunch over time, simply pop them in a 300°F oven for 5-7 minutes to refresh their texture. Let them cool briefly afterward and enjoy that fresh-baked crispness all over again.

FAQs

Can I use a different type of flour for this Cinnamon Sugar Crisps Recipe?

Absolutely! While all-purpose flour is the standard, you can try whole wheat, spelt, or even gluten-free blends. Just be mindful that different flours may affect the dough’s texture and baking time slightly.

Is sourdough discard necessary or can I omit it?

The sourdough discard adds a unique tang and tenderness to these crisps but if you don’t have any, you could substitute with yogurt or buttermilk for some acidity, or even plain milk for a milder flavor.

How thin should I roll out the dough?

Roll the dough to about 1/8 inch thickness. This ensures the crisps become delightfully crunchy after baking without burning.

Can I make these crisps spicy or add other flavors?

Definitely! Try adding a pinch of nutmeg or ground cloves for extra spice, or sprinkle some finely chopped nuts for crunch. The cinnamon sugar base is very versatile.

What’s the best way to make the crisps extra crispy?

Make sure to roll the dough thinly and bake until the edges are golden brown. Also, letting them cool completely before storing helps maintain that crispy texture.
