Preheat oven to 350 degrees and place oven rack in center position. Cover a cookie sheet with parchment paper

Dust counter with flour

Remove thawed pie crust from pan, if it keeps it's shape just lay it flat on prepared counter, if it doesn't,  shape into a ball with your hands and roll dough into an oval shape at least 8" wide

Use a knife to cut into the shape of a heart, set on parchment covered cookie sheet (note: I free hand the heart shape, but you could also fold parchment in half, draw half a heart, cut and unfold, then use as a template...think elementary school days:)

Place heart shaped dough on parchment covered cookie sheet. Set aside.

Set a pan on cooktop on medium heat. Add butter, allow to melt, add brown sugar (or maple syrup) and cinnamon, stir until sugar is melted

Add apples and cook until soft (4-5 minutes)

Use a slotted spoon to remove apple slices leaving as much butter/melted sugar in pan as you can

Arrange apple slices on pie crust, starting on the outer edges and spiraling your way to the center, leaving 1" around the edges bare. Fold the edges over making a bit of a frame around your heart. Bake for about 12 minutes or until pie crust is cooked.

When tart is ready, take out of oven, allow to cool for 4-5 minutes. While tart cools: reheat the butter/sugar mixture remaining in pan on low heat. When melted, add cream to pan and whisk until it turns into a nice caramel. Turn off heat.

After tart has cooled, add a scoop of ice cream to the center of tart, add walnuts, and spoon caramel sauce over ice cream and apples. Serve!
