In the mixing bowl of a Stand Mixer, add the Butter, Sugar, and Egg, and blend with the Whisk attachment until smooth, and creamy.

Add the Vanilla, and mix until blended. In a separate bowl, add the Flour, and Salt, and mix well to blend.

Add the Flour mixture to the mixing bowl, and mix until blended, and smooth.

Divide the dough into 5 chunks of dough and place each piece of dough in a bowl.

Add gel food coloring to each bowl and mix with a spoon until dough is the desired color, about 3 drops of color to each dough section.

Next, place the dough on a piece of parchment paper, sprinkle the dough with flour and roll out to 1/2" thickness.

Then take the heart cookie cutter and cut out hearts.

Remove the excess dough from around the edges and you are ready to stamp each cookie.

Take a cookie stamp and lay it on top of one of the hearts.

Remove from the oven to a wire rack, and cool completely.
