Heat a large skillet over medium heat with some butter or oil. Once the pan is hot, add in your sliced pieces and cook for about 5 minutes until they’re nice and soft.
While your peaches are cooking, make your glaze by combining the water, sugar, cornstarch, vanilla extract, lemon juice, egg, melted butter, and ½ teaspoon of cinnamon in a medium bowl. Whisk everything together until it’s combined.
Once your peaches are cooked through, add them to the glaze and mix everything together until it’s combined.
Now you’re ready to assemble your egg rolls! Place an egg roll wrapper on a flat surface in front of you. Take one tablespoon of the peach filling and place it onto the center of the wrapper.
Fold over one corner of the wrapper, and then fold in each side before rolling up the whole thing, making sure to press down firmly so everything sticks together.
Dip the egg roll in the melted butter.
Place the egg rolls on a parchment-lined baking sheet in preheated oven at 400 degrees, and bake for 15-20 minutes until golden brown and crispy.
Mix together 1 Tbsp of brown sugar and 1 Tbsp of cinnamon in a bowl, and coat the butter-dipped egg rolls in the mixture.
Ready to serve!
