This Cherry Toaster Strudel is the grown up version of a childhood classic. Thanks to puff pastry, these come out flakey, perfectly sweet, and irresistible.
In a small saucepan, add pitted cherries, lemon juice, and sugar. Mix until combined. Bring to a low boil.
In a small ramekin, combine cornstarch and 1 tbsp of water. Mix. Add the cornstarch slurry into the cherries and stir. Simmer for 4 - 6 minutes or until the cherries have released their juices.
Remove from heat and mix in vanilla. Allow to cool.
For the Strudel
Preheat oven to 375℉. Lay out both sheets of thawed puff pastry onto a lightly floured surface. Cut each sheet into 6 equal pieces (so 12 total).
Have a small ramekin of water ready. Spoon 2 - 3 tbsp of cherry filling into the middle of 6 dough rectangles. Dip your finger in the ramekin and wet along the edges of the dough.
Carefully top the cherry dough rectangles with a rectangle, closing the filling in. Gently press down around the edges. Use a fork to crimp around the edges. (It's ok if a little filling juice spills out). If you're making the icing, reserve 1 tbsp of cherry liquid.
Brush the tops with egg wash. Use a fork to pierce the top 3 times to allow steam to release. Bake for 30 minutes.
Remove from oven and cool for 5 minutes.
For the Icing (optional)
In a small bowl mix the cherry liquid and powdered sugar until smooth. Add more liquid if needed. Drizzle on top of baked toaster strudels.
