How to Make Sourdough Cinnamon Toast Crunch
-
Preheat your oven to 350°F. This step is crucial for achieving that perfect golden crunch, so don’t skip it!
-
Mix the sugar and cinnamon together in a small bowl, combining 1/2 cup sugar and 1 tablespoon of ground cinnamon. Set this sweet mixture aside to use later.
-
Melt 1/4 cup of butter in a small dish until it’s completely liquid. Let it cool slightly before setting it aside; we want it warm, not hot!
-
Whisk together the flour, 1/4 cup granulated sugar, 1 tablespoon cinnamon, and salt in a large bowl. This will create a beautiful base for your dough.
-
Shred the cold butter using a box grater and add it to the dry ingredients. Use a pastry cutter or fork to mix until the mixture resembles pea-sized crumbs.
-
Add the sourdough starter and vanilla extract into the bowl. Use a fork to begin combining them, then switch to your hands to form a cohesive dough ball, adding cold water if needed.
-
Divide the dough in half and turn it onto a clean work surface. This will make it easier to roll out each half separately.
-
Roll one half of the dough on a piece of parchment paper until it’s about 1/8-inch thick, creating a lovely rectangle perfect for cutting.
-
Cut the dough into 1/2-inch squares using a pizza cutter. Transfer the squares on the parchment paper to a baking sheet, ensuring they’re spaced apart.
-
Brush the tops of the dough squares with the melted butter and sprinkle generously with the cinnamon sugar mixture you prepared earlier.
-
Bake for 15-20 minutes until the squares are golden brown and delightfully crunchy. Allow them to cool to room temperature before indulging!
Optional: Serve with a drizzle of icing for an extra touch of sweetness!

Tips for the Best Sourdough Cinnamon Toast Crunch
-
Measure Carefully: Accurate measurements are key to achieving the perfect texture. Too much flour can yield dry bites, so level your cups!
-
Shred Cold Butter: Ensure your cold butter is shredded; this helps create those delightful flaky layers. If you use melted butter instead, the texture will suffer.
-
Use Active Starter: Make sure your sourdough starter is active and bubbly for enhanced flavor. A weak starter can lead to a disappointing result.
-
Watch the Bake Time: Keep a close eye while baking; the cinnamon squares can quickly go from golden to overdone. Remove them once they’re lightly browned for optimal crunch.
-
Let Cool: Allow the crunch to cool completely before serving. This helps maintain its crispy texture and allows the flavors to meld beautifully.
Make Ahead Options
These Sourdough Cinnamon Toast Crunch squares are perfect for meal prep enthusiasts! You can prepare the dough up to 24 hours in advance by following the recipe instructions up to the point of cutting it into squares. Once cut, simply layer the squares on a baking sheet, cover them tightly with plastic wrap, and refrigerate. This helps preserve their flavor and texture. When you’re ready to bake, just remove them from the fridge and proceed with brushing melted butter and sprinkling the cinnamon sugar mixture. Baking them freshly from the fridge ensures you’ll still enjoy that warm, crispy goodness that makes this treat so irresistible!
How to Store and Freeze Sourdough Cinnamon Toast Crunch
Room Temperature: Store leftover pieces in an airtight container at room temperature for up to 3 days. This will keep them crunchy and delicious!
Fridge: For longer freshness, you can refrigerate the crunch in a sealed container for up to a week, but note that they may lose some crispiness.
Freezer: If you want to save some for later, freeze the pieces in a single layer on a baking sheet, then transfer to a freezer bag. They’ll last for up to 2 months.
Reheating: To enjoy them again, simply reheat in the oven at 350°F for about 5-7 minutes until warmed through, reviving that delightful crunch!

If your dough feels crumbly or too dry, don’t fret! Just add 1 tablespoon of cold water at a time while mixing until it comes together as a cohesive ball. You want it to be firm but not sticky—so go slow, and trust your instincts!
Can I make this recipe gluten-free?
Certainly! You can use a gluten-free all-purpose flour blend as a substitute for regular flour. Just ensure the blend you choose has xanthan gum or a similar binder included. Keep in mind that the texture may vary a bit from the original version, but the yummy flavors will still shine through!
