Make the Easy Vegan Pie Crust and press it into the bottom of a 9 x 9-inch baking dish. Do not bake the crust.
Make the Filling
Combine all ingredients into a high-walled saute pan at room temperature. Stir until cornstarch is fully dissolved.
Heat over medium to high heat, stirring constantly until the mixture thickens.
Pour the thickened mixture over the uncooked pie crust and bake at 400F for 15 minutes.
Allow the bars to cool and set for 30-60 minutes before slicing.
Dust with powdered sugar, slice, serve, and enjoy!
Notes
Not Vegan? Use dairy milk instead of plant milk
Gluten-Free? Use a 1:1 gluten-free flour replacement for the pie crust, or your favorite gluten-free pie crust recipe and you're all set. Make sure to opt for a gluten-free plant milk as well.
*A note about granulated sugar: Not all granulated sugar is vegan, make sure to choose a USDA Organic variety to ensure it is not processed with bone char, an animal ingredient.
