Beat heavy cream in a chilled bowl until thickened.
Add vanilla extract, ground ginger and ground cinnamon. Beat until stiff peaks form.
Fold in sweetened condensed milk until combined. Scrap into a 9-inch loaf pan.
Melt butter in a medium-sized, microwave-safe bowl. Add the PEEPS® and stir to coat with the melted butter. Microwave on high for 60 seconds. Stir until smooth.
Allow the melted PEEPS® to cool for 2-3 minutes and then use a greased fork or spatula to drizzle over the ice cream in the loaf pan. Use a knife to swirl the marshmallow through the loaf pan.
Cover tightly with plastic wrap and then foil. Freeze overnight and for up to 7 days.
