Homemade Toaster Strudel Treat

Category: Start Your Day Deliciously

This homemade version features buttery puff pastry cut into rectangles and filled with a flavorful berry jam mixture thickened with cornstarch. After sealing the edges with an egg wash, the strudels bake to a golden brown, developing a flaky texture. The final touch is a smooth sweet icing made with powdered sugar, half and half, vanilla, and almond extracts, drizzled over each warm pastry. Use your preferred jam and ensure puff pastry is thawed for best results.

Preparation includes layering pastry sheets carefully, sealing the filling to avoid leaks, and brushing with an egg wash for a glossy finish. Baking time is around 20 minutes until golden. This treat captures a balance of crisp pastry and sweet, tangy jam, perfect for a comforting snack or breakfast addition.

This homemade toaster strudel brings a touch of bakery magic to your kitchen using simple ingredients and straightforward steps. Perfect for weekend mornings or special breakfasts, these golden pastries with berry filling and sweet icing are a delightful treat that beats any store-bought version.

I threw these together when craving a nostalgic breakfast and found the homemade version just as satisfying as the frozen packs but fresher and less processed.

Ingredients

  • Puff pastry sheets: provide a flaky buttery crust make sure they are fully thawed for easy handling and best puffing
  • Berry jam: is the star of the filling choose fresh vibrant tins without additives for true fruit flavor
  • Cornstarch: helps thicken the filling so it stays put during baking preventing soggy layers
  • Large egg: combined with water creates the perfect egg wash to seal and glaze the pastries
  • Salted butter: melted into the dough adds richness and enhances browning
  • Powdered sugar half and half vanilla extract and almond extract: make up the classic icing that balances tang and sweetness always use fresh powdered sugar for smooth icing

Instructions

Preheat the Oven:
Set your oven to 400 degrees Fahrenheit and prepare a baking sheet lined with parchment or a silicone mat to prevent sticking and easy cleanup.
Prepare Puff Pastry and Filling:
Lightly flour your work surface to prevent sticking. Lay out one sheet of puff pastry and cut it into six equal rectangles using a sharp knife or pizza cutter. In a small bowl whisk together your chosen berry jam with cornstarch to thicken it slightly.
Assemble the Strudels:
Spoon about one and a half tablespoons of the jam mixture onto three of the pastry rectangles leaving a half-inch border around the edges clear of filling.
Seal with Egg Wash:
Beat the egg with a tablespoon of water to make the egg wash. Carefully brush the edges around the jam on each rectangle to act as glue for sealing. Place the corresponding plain pastry rectangles over the jam-topped ones and press the edges firmly with your fingertips to seal them well ensuring no jam leaks during baking.
Bake Until Golden:
Lightly brush the tops of each assembled strudel with the remaining egg wash for a gorgeous golden finish. Bake on the prepared sheet for about 20 minutes or until puffed and golden brown. Remove and let cool on a wire rack until warm to the touch.
Make and Drizzle the Icing:
Whisk together powdered sugar half and half vanilla extract and almond extract in a small bowl until smooth. Adjust the consistency with more half and half if needed so it drizzles nicely. Transfer the icing to a small resealable bag snip a tiny corner and drizzle it evenly over the warm strudels for a classic finish.

My favorite part is the buttery crisp layers of the puff pastry paired with the jam’s fruity zing. Making these reminds me of cozy family breakfasts where everyone gathered around the kitchen sharing stories as the warm strudels baked.

Storage Tips

Store leftover strudels in an airtight container at room temperature for up to two days To keep them fresh longer refrigerate and reheat in a toaster oven or regular oven for best texture I learned the hard way reheating in a microwave makes them soggy so slow and steady is better

Ingredient Swaps

Use apricot or peach jam for a different sweet note that complements the buttery crust If you do not have cornstarch arrowroot powder works well as a thickener too For a dairy-free version swap half and half with coconut milk and use a dairy-free puff pastry

Serving Ideas

Serve warm with a dollop of whipped cream or vanilla yogurt for brunch or dessert A sprinkling of fresh berries on the side adds brightness and contrast Pair with a cup of coffee or tea to balance the sweetness and create a comforting morning ritual

Frequently Asked Recipe Questions

→ What type of puff pastry works best?

Use thawed, store-bought puff pastry sheets for an even rise and flaky layers. Ensure they are completely thawed but still cold before shaping.

→ Can I use different jams for the filling?

Absolutely, a variety of berry jams like strawberry, raspberry, or blueberry work well and can be mixed to customize the flavor.

→ How do I prevent the filling from leaking?

Brush the pastry edges with an egg wash before sealing to help them stick tightly. Press edges firmly to create a good seal.

→ What’s the purpose of cornstarch in the filling?

Cornstarch thickens the jam filling as it heats, preventing it from becoming too runny during baking.

Guide to Cooking

Step 01

Preheat the oven to 204°C. Line a baking sheet with a silicone liner or parchment paper.

Step 02

On a lightly floured surface, lay one sheet of puff pastry and cut into six equal rectangles. In a small bowl, whisk together the berry jam and cornstarch.

Step 03

Spoon approximately 22 ml of the jam mixture onto three rectangles, leaving a 1.3 cm rim around edges. Whisk the egg with 15 ml water and brush this mixture lightly on the exposed rims to assist sealing.

Step 04

Place the remaining three rectangles of puff pastry atop the jam-coated ones. Press the edges firmly to seal. Transfer assembled pastries to the refrigerator while repeating the process with the second sheet.

Step 05

Lightly brush the tops of the strudels with the egg wash. Bake for 20 minutes or until golden brown.

Step 06

Meanwhile, whisk together powdered sugar, half and half, vanilla, and almond extracts until smooth. Add additional half and half if necessary to thin. Once strudels have cooled until warm, drizzle the icing over the top using a resealable bag with a cut corner.

Extra Suggestions

  1. Use your preferred berry jam to customize flavor. Ensure puff pastry is fully thawed for optimal texture. Brown butter can be substituted in the icing for added richness.
