In a saucepan over medium heat, add raspberries, sugar, brown sugar, lemon zest, lemon juice, and cornstarch. Stir and bring to a boil until the raspberries start to thicken. Let cool.
On a lightly floured surface, lay out crescent dough, one can at a time, and pinch the perforated lines together.
Roll dough so edges are even.
Carefully slice into 1-inch strips lengthwise and then cut each strip in half. (Should have 14 pieces of dough from each can of crescent rolls)
Add some raspberry mixture down the center of one strip.
Place another strip on top of the raspberry mixture.
Gently twist the two strips together and lay on the prepared baking sheet.
Repeat with the remaining ingredients.
Bake for 10-12 minutes or until golden.
Remove from the oven and let cool.
