Full Recipe:

Ingredients

Sourdough Puff Pastry:

205g all-purpose flour
7g salt
226g (2 sticks) salted butter, cold and grated
60g water
113g sourdough discard

Brown Sugar Cinnamon Filling:

6 tbsp brown sugar
1/2 tbsp all-purpose flour
1/2 tbsp cinnamon
1 tbsp salted butter, melted
1 tsp vanilla extract
1 egg + 1 tbsp milk (for egg wash)

Simple Glaze:

1/2 cup powdered sugar
1 tbsp milk of choice
1/2 tsp vanilla extract

Directions

Prepare the sourdough puff pastry:

In a medium bowl, whisk together the sourdough discard and water.
In a separate large bowl, whisk together the flour and salt. Add the grated butter and mix to coat.
Make a well in the center and pour in the discard mixture. Stir until a dough forms, then knead until combined.
Wrap the dough in plastic wrap, flatten it into a rectangle, and refrigerate for 30 minutes.

Laminate the dough and chill:

On a floured surface, roll out the dough into a large rectangle (~18”x8”).
Perform a book fold by folding the short sides towards the middle and then folding in half. Wrap and chill for 30 minutes.
Repeat 2-3 letter folds (rolling and folding like a letter), chilling 30 minutes between each fold.
After the last fold, refrigerate for at least 1 hour before using.

Preheat oven and prepare the pan:

Preheat oven to 400°F and line a baking sheet with parchment paper.

Make the toaster strudels:

Prepare the filling by mixing all ingredients in a bowl.
Divide the sourdough puff pastry in half, saving one half for later.
Roll out the pastry slightly and cut into 12 small rectangles.
Spoon ~1/2 tbsp of filling onto 6 rectangles, leaving a border.
Brush the edges with egg wash, cover with remaining rectangles, and press the edges together.
Use a fork to crimp the edges and transfer to a baking sheet.
Brush the tops with egg wash and bake for 15-18 minutes, until golden brown.
Let cool slightly before glazing.

Make the glaze & finish:

Whisk together all glaze ingredients in a bowl.
Drizzle or spread over the toaster strudels.
Enjoy!

Why Make Homemade Toaster Strudels?

Many people grew up enjoying store-bought toaster strudels, popping them into the toaster and drizzling on the signature icing. However, making them from scratch offers several benefits:

Superior Flavor: The combination of real butter, sourdough, and brown sugar cinnamon creates a deeper, richer taste than any processed version.
Healthier Ingredients: Store-bought strudels often contain artificial flavors, preservatives, and excess sugar. With homemade ones, you control the quality of ingredients.
Sourdough Benefits: Incorporating sourdough discard into the pastry enhances the flavor while reducing food waste, making this a sustainable and delicious recipe.
Customizable: You can adjust the sweetness, spice level, or even swap the filling for jam, Nutella, or cream cheese to create a variety of flavors.

The Magic of Sourdough Puff Pastry

Traditional puff pastry relies on layers of butter and dough to create its signature flakiness. In this recipe, sourdough discard adds a new dimension of flavor and texture to the pastry. The natural fermentation in the discard creates a slight tang, balancing the richness of the butter and the sweetness of the filling.

Laminating the dough (rolling and folding it multiple times) is what gives the pastry its delicate layers. This process requires some patience, as the dough needs to be chilled between folds, but the result is a perfectly flaky and golden crust that makes these toaster strudels irresistible.

The Perfect Brown Sugar Cinnamon Filling

The filling of these mini toaster strudels is simple but packed with flavor. Brown sugar provides a rich sweetness with hints of caramel, while cinnamon adds warmth and spice. A touch of vanilla extract enhances the overall flavor profile, and a small amount of flour helps bind everything together to prevent the filling from leaking out during baking.

This classic combination gives the strudels a taste reminiscent of cinnamon rolls or warm spiced pastries, making them ideal for a cozy breakfast or afternoon snack.

A Simple Yet Delicious Glaze

A toaster strudel isn’t complete without its signature icing, and this simple vanilla glaze ties everything together beautifully. Made with powdered sugar, vanilla extract, and a splash of milk, it’s just the right amount of sweetness without overpowering the pastry.

Drizzling or spreading the glaze while the strudels are still slightly warm allows it to melt slightly into the flaky layers, creating a delicious contrast of textures with every bite.

What Makes These Toaster Strudels Special?

Flaky and Buttery Texture: Thanks to the sourdough puff pastry, these strudels have an incredible texture that’s crispy on the outside yet soft and rich on the inside.
Warm and Comforting Flavor: The brown sugar cinnamon filling provides a nostalgic, homey taste that pairs perfectly with coffee or tea.
Easy to Store and Reheat: You can make a batch ahead of time, store them in the fridge or freezer, and simply reheat them in the oven or air fryer for a quick and delicious breakfast.
Fun to Make: While they do require some preparation, making these strudels is a rewarding baking project that’s perfect for weekend baking or holiday treats.

Serving Suggestions

These mini toaster strudels are delicious on their own, but if you want to elevate your breakfast or snack time, try pairing them with:

A cup of coffee or chai tea – The warm spices in the filling complement coffee’s richness or the spices in chai.
Fresh fruit – Berries, sliced apples, or a fruit salad add a fresh contrast to the sweet and buttery pastry.
Whipped cream or Greek yogurt – A dollop of lightly sweetened whipped cream or a scoop of yogurt balances the sweetness and adds creaminess.
Maple syrup drizzle – For an extra indulgent touch, a light drizzle of maple syrup enhances the cinnamon flavors beautifully.

Storage and Reheating Tips

One of the best parts about these homemade strudels is that they store well, making them perfect for meal prep.

Refrigeration: Store leftover toaster strudels in an airtight container in the refrigerator for up to 3 days.
Freezing: Freeze unbaked or fully baked strudels for up to 2 months. If freezing unbaked, simply bake them straight from the freezer, adding a few extra minutes to the baking time.
Reheating: To enjoy them warm, reheat in a 350°F oven for about 5-7 minutes or pop them in an air fryer at 325°F for a few minutes until heated through. Avoid microwaving, as this can make the pastry soggy instead of crispy.

Variations and Customizations

Once you’ve mastered the base recipe, get creative with your fillings and flavors! Here are a few fun ideas:

Apple Cinnamon: Add finely chopped apples to the brown sugar cinnamon mixture for a fall-inspired treat.
Nutella & Banana: Spread Nutella inside and top with thin banana slices before sealing.
Cream Cheese & Berry Jam: A tangy cream cheese and fruit jam filling makes these taste like mini Danish pastries.
Pumpkin Spice: Replace the cinnamon with pumpkin spice for a seasonal twist.
Almond & Honey: Add slivered almonds and a drizzle of honey inside for a nutty, slightly floral flavor.

The Joy of Baking with Sourdough Discard

If you maintain a sourdough starter, you know how often you end up with leftover discard that needs to be used. Rather than throwing it away, this recipe is a great way to put it to delicious use. Sourdough discard not only enhances the texture of baked goods but also adds a subtle tang that makes pastries even more flavorful.
