Marbled Heart Cookies

I don’t know about you, but I believe one of the best ways to tell someone you love them is through making them something yummy to eat.

Cooking and baking takes time, passion and patience which are 3 ingredients to love.

Seriously, haven’t you heard the saying, “The way to a man’s/woman’s heart is through their stomach?”

That is why I love making tasty treats for Valentine’s Day like these Valentine Peanut Butter M&M’s Bars, Valentine Unicorn Cake, Red Velvet Heart Crinkle Cookies and even this Strawberries and Chill Cocktail.

With that being said, these Heart Cookies are a soft, chewy sugar cookie covered with a sugary, marbled royal icing. They are truly almost too pretty to eat!

Marbled Cookies Tips

  • Be careful to not overcook the cookies. If they are golden brown, you overcooked them. They are done when they are set and no longer shiny, don’t wait for the edges to turn. 
  • Gel food coloring works best especially for a vibrant color.
  • The icing is really interesting, each time I make this I seem to use a different amount of milk. Add more or less milk as needed. The icing should be the consistency of Elmer’s glue.

Cover the dough and place in the refrigerator for one hour.

While the dough is chilling, preheat the oven to 350 degrees and line a baking sheet with parchment paper. 

Remove dough from the refrigerator and roll out onto a floured surface about a half of an inch thick and cut into desired shapes.

Bake for 10-12 minutes or until the cookies are set.

Meanwhile, prepare the icing by combining the confectioners sugar, milk and corn syrup in a small bowl.

Add more or less milk to adjust consistency.  Squeeze a small amount of food coloring into the icing and use a toothpick to drag the color across the surface.
