Mix cornstarch and water in a bowl.
Pour the cornstarch mixture, brown sugar, salted butter, and sliced peaches into the saucepan. Cook until the liquid begins to bubble, stirring continuously.
Once the mixture thickens, remove the pan from the heat. Stir in the vanilla extract. Allow the peach filling to cool.
To assemble the peach cobbler egg rolls, overlap two wrappers over a flat surface. Arrange the wrappers in the shape of a diamond.
Place a tablespoon of the cooled peach mixture into the center of the wrap.
Bring the bottom corner up and over the filling. Next, take the two side corners and bring them to the center.
Brush the top corner with water, then roll the egg roll up to finish. Repeat with the remaining wrappers and peach mixture. Press the edges gently to secure the wrappers in place.
On a separate plate, mix the granulated sugar and cinnamon. Set aside.
Heat your oil in a frying pan. To know when it’s ready, dunk the handle of a wooden spoon into the oil. It’s good to go once you see bubbles forming around the spoon.
Fry the peach cobbler egg rolls in the oil for 3 to 6 minutes or until crispy and golden brown on both sides.
Place the fried peach cobbler egg rolls over paper towels to absorb the excess oil.
After 2 minutes, roll the warm peach cobbler egg rolls in the cinnamon sugar mixture.
Serve and enjoy!
