Preheat your oven to 350 degrees. Line your pie pan with a 9 inch pie crust.

Add in your flour, brown sugar, and dash of salt. Gently stir it right in the pie pan, and spread it evenly.

Now you will pour the evaporated milk over the brown sugar mixture. Do not stir and then slice the butter and lay over the pie mixture.

Sprinkle with cinnamon and bake for 50-60 minutes. The pie will bubble in the center.

Allow the pie to fully cool.

Then once pie is cooled whip heavy cream in bowl until it is nice and thick. Add in powdered sugar and mix on low speed until well incorporated.

Spread the whipped cream over the pie with a piping bag or spatula.
