Preheat your oven to 350°F (175°C) to ensure even baking.
Prepare your 9x13 inch baking dish with non-stick cooking spray or butter.
In a mixing bowl, combine the melted butter, brown sugar, and 3 tablespoons of heavy whipping cream. Add pecans if using, and mix until creamy.
Open the cans of cinnamon rolls and place them in the prepared baking dish, spaced evenly. Pour the butter and sugar mixture over them.
Pour 1 cup of heavy whipping cream over the cinnamon rolls for a soft texture.
Bake in the preheated oven for 25-30 minutes until golden brown and cooked through.
Allow to cool slightly, then drizzle the icing over the warm rolls.
