Creating Heart-Shaped Cinnamon Rolls is a straightforward and enjoyable process. Just follow these simple steps:

1. Warm the Milk: In a small saucepan, warm the milk over low heat until it's lukewarm. Remove from heat.
2. Prepare the Yeast: Add the active dry yeast and 1 tablespoon of sugar to the warm milk. Let it sit for about 5-10 minutes until foamy.
3. Mix Dry Ingredients: In a large mixing bowl, combine flour, remaining sugar, and salt. Mix well.
4. Add Wet Ingredients: In a separate bowl, whisk together the melted butter and eggs. Once combined, add the yeast mixture and stir.
5. Combine Mixtures: Gradually add the liquid ingredients to the dry ingredients. Mix until a dough forms.
6. Knead the Dough: Transfer the dough to a floured surface. Knead for about 5-7 minutes until it becomes smooth and elastic.
7. First Rise: Place the dough in a greased bowl, cover it with a clean towel, and let it rise in a warm place for 1 hour or until doubled in size.
8. Prepare Filling: In a small bowl, mix brown sugar and ground cinnamon to create the filling.
9. Roll Out the Dough: After the dough has risen, punch it down and roll it out on a floured surface into a rectangle (about 14"x10").
10. Spread Butter: Spread the softened butter evenly over the surface of the dough.
11. Add Filling: Sprinkle the cinnamon-sugar mixture evenly over the buttered dough.
12. Shape the Rolls: Starting from the long edge, carefully roll the dough tightly into a log. Pinch the seams to seal.
13. Cut Rolls: Cut the log into 12 equal pieces.
14. Create Heart Shapes: Take each piece and shape it into a heart by inviting the two cut ends towards the center and tucking one end underneath.
15. Second Rise: Place the heart-shaped rolls on a greased baking sheet, cover them, and let them rise for an additional 30 minutes.
16. Preheat Oven: While the rolls are rising, preheat your oven to 350°F (175°C).
17. Bake Rolls: Bake the rolls in the preheated oven for 25-30 minutes, or until they are golden brown.
18. Prepare Icing: While the rolls are baking, whisk together powdered sugar, milk, and vanilla extract in a small bowl until smooth.
19. Cool Rolls: Allow the rolls to cool for about 10 minutes after baking.
20. Drizzle Icing: Drizzle the icing over the warm cinnamon rolls before serving.

With these steps in hand, your Heart-Shaped Cinnamon Rolls will turn out beautifully and be sure to impress!
