Ingredients You’ll Need
The ingredient list is short, making this a convenient recipe for using up sourdough discard.
For the Crisps
- 1 cup unfed sourdough discard, room temperature
- 1/4 cup unsalted butter, melted and slightly cooled
- 1/3 cup granulated white sugar or brown sugar
- 2 teaspoons ground cinnamon
- 1 teaspoon pure vanilla extract
- 1/4 teaspoon fine sea salt
For the Cinnamon-Sugar Topping
- 2 tablespoons granulated sugar
- 1 teaspoon ground cinnamon
Optional
- A light spray of olive oil
- A small amount of melted butter for brushing the top
- Finely chopped pecans or almonds
- A pinch of flaky sea salt
Room-temperature sourdough discard is particularly convenient because it combines easily with the melted butter and other ingredients.
What Kind of Sourdough Discard Should You Use?
This recipe is designed for unfed sourdough discard, making it a useful option when you are maintaining a sourdough starter.
Your discard should have been stored properly and should have its normal pleasantly tangy or fermented aroma. If you notice mold or an unusual spoiled smell, discard it rather than using it in a recipe.
You do not need to feed the starter specifically for these crisps. The unfed discard works well because the goal is flavor and texture rather than fermentation and rising.
How to Make Sourdough Discard Cinnamon Sugar Crisps
Step 1: Prepare the Oven
Preheat your oven to 325°F (165°C).
Line a large baking sheet with parchment paper or use a silicone baking mat.
Lining the tray is important because the thin batter contains sugar and butter, which can become sticky as they bake. A lined baking sheet makes the finished crisps much easier to remove.
Step 2: Mix the Batter
Place the room-temperature sourdough discard in a large mixing bowl.
Add the melted and slightly cooled butter, sugar, cinnamon, vanilla extract, and sea salt.
Use a whisk or spatula to mix everything together until the mixture looks smooth and evenly combined.
Make sure the butter has cooled somewhat before mixing it into the discard.
Step 3: Spread the Mixture
Pour the cinnamon-sourdough mixture onto the center of the prepared baking sheet.
Use an offset spatula or the back of a spoon to spread it into a very thin, even layer.
This is the most important step for achieving a crisp texture. If some areas are significantly thicker than others, the thin edges may become dark before the thicker center is fully crisp.
Take your time and spread the mixture as evenly as possible.
Step 4: Add the Cinnamon-Sugar Topping
In a small bowl, combine the 2 tablespoons of sugar with 1 teaspoon of cinnamon.
Mix well.
Sprinkle the cinnamon-sugar mixture evenly over the entire surface of the batter.
If you want a slightly richer finish, lightly brush or spray the surface with a small amount of butter or oil before adding the topping.
Avoid adding too much extra fat because the recipe already contains butter.
Step 5: First Bake
Place the baking sheet on the center rack of your preheated oven.
Bake for approximately 15 minutes.
At this point, the mixture should have set enough to handle carefully.
Remove the tray from the oven using oven mitts.
Step 6: Score the Crisps
While the baked sheet is still warm, use a pizza cutter or sharp knife to score it into squares or rectangles.
You do not necessarily need to cut all the way through. The goal is to create lines that will make the crisps easier to separate once they are completely baked.
You can make the pieces large or small depending on how you plan to serve them.
Step 7: Continue Baking
Return the baking sheet to the oven.
Bake for another 15–20 minutes, keeping a close eye on the crisps during the final few minutes.
The exact time can vary depending on how thinly you spread the batter and how your oven heats.
The edges should become a deep golden brown, while the center should feel firm.
Because the topping contains sugar, it can darken quickly toward the end of baking. Check frequently during the last few minutes.
Step 8: Cool Completely
Remove the tray from the oven and let the crisps cool completely on the baking sheet for at least 20 minutes.
Do not rush this step.
The crisps become firmer and crunchier as they cool. Once completely cooled, break them apart along the scored lines.
Transfer the pieces to a serving plate or airtight container.
The Secret to Extra-Crispy Crisps
The biggest secret is simple: spread the batter thinly and evenly.
A thick layer will retain more moisture and may remain chewy in the center. A thin layer allows the moisture to evaporate during baking, producing the delicate crunch that makes these crisps so enjoyable.
Cooling is equally important. The crisps may seem slightly softer when they first come out of the oven, but they will firm up as they cool.
If they are still softer than you prefer after cooling, you can return them to a low oven for a few additional minutes. Watch carefully because the sugar can brown quickly.
Easy Flavor Variations
This recipe is easy to customize.
Cinnamon Nut Crisps
Add finely chopped pecans, walnuts, or almonds to the surface before baking. The nuts provide another layer of crunch and pair beautifully with cinnamon.
Cardamom Cinnamon Crisps
Add a small pinch of ground cardamom to the batter along with the cinnamon for a fragrant, slightly exotic flavor.
Nutmeg Spice Crisps
For a cozy fall-inspired version, add a pinch of nutmeg to the cinnamon mixture.
Pumpkin Spice Crisps
Replace part of the cinnamon with your favorite pumpkin pie spice blend.
Almond Vanilla Crisps
Add a small splash of almond extract along with the vanilla. The combination works especially well with the buttery base.
Sweet and Salty Crisps
Sprinkle a tiny amount of flaky sea salt over the cinnamon-sugar topping before baking. The salty contrast can make the sweetness and cinnamon taste even more pronounced.
How to Serve Cinnamon Sugar Crisps
These crisps are delicious straight from the container, but there are many other ways to enjoy them.
Serve them alongside:
- Coffee
- Tea
- Hot chocolate
- Vanilla yogurt
- Cream cheese
- Peanut butter
- Fresh berries
- Fruit dip
- Chocolate sauce
- Vanilla ice cream
You can also crush the crisps into small pieces and use them as a crunchy topping for ice cream, oatmeal, yogurt bowls, or fruit parfaits.
For a party, arrange them on a dessert platter alongside fresh fruit and creamy dips.
How to Store Them
The goal when storing these crisps is to protect their crunch.
Allow them to cool completely before placing them in an airtight glass jar or metal container.
Store them at room temperature in a cool, dry place.
If you live in a humid environment, pay particular attention to storage because moisture can soften thin baked crisps.
Avoid sealing them in a container while they are still warm. Any trapped steam can create moisture and reduce their crisp texture.
How to Restore Their Crunch
If the crisps become soft after storage, you do not necessarily need to throw them away.
Place them on a baking sheet and warm them in a 300°F (150°C) oven for about 3–5 minutes.
Let them cool completely before serving.
Keep a close eye on them because thin crisps can darken quickly.
Can You Add Nuts?
Yes. Nuts are an excellent addition to this recipe.
Finely chopped pecans are especially delicious with cinnamon and brown sugar. Sliced almonds and walnuts also work well.
For the best texture, use a relatively small amount and distribute the nuts evenly over the surface before baking.
Frequently Asked Questions
Can I use brown sugar instead of white sugar?
Yes. Brown sugar can give the crisps a slightly deeper, richer flavor. White sugar provides a more straightforward sweetness and can create a lighter finish.
Does the sourdough starter need to be active?
No. Unfed sourdough discard is ideal for this recipe.
Can I use cold discard?
You can, although room-temperature discard is easier to mix with melted butter. If your discard is refrigerated, allow it to warm slightly before preparing the batter.
Why aren’t my crisps crunchy?
The most common reason is that the mixture was spread too thickly. Uneven thickness can also cause some areas to remain soft while the edges become overbaked.
Allow the crisps to cool completely before judging their final texture.
Why did my crisps brown too quickly?
Sugar can caramelize quickly, particularly around thin edges. Keep a close eye on the crisps during the final stage of baking.
Can I make larger pieces?
Yes. Simply score the baked sheet into larger rectangles or squares. Smaller pieces are convenient for snacking, while larger pieces can be served alongside dips or desserts.
