Method
 

Step-by-Step Instructions
  1. In a large mixing bowl, cream together the butter and sugar on medium speed until light and fluffy, about 3-5 minutes.
  2. Add beaten eggs and vanilla extract, mixing on medium speed until smooth and pale, about 1-2 minutes.
  3. Gradually sift in the flour and baking soda, mixing on low speed until fully incorporated.
  4. Divide the dough onto a lightly floured surface, leaving one portion white and adding food coloring to the other four to create a marbled effect.
  5. Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper. Drop pieces of the colored dough onto the sheet.
  6. Gently press the dough down to about ¾ inch thick. Bake for 10-15 minutes until edges are golden but the center is underbaked.
  7. Allow the cookie bars to cool completely on a wire rack before frosting with buttercream and optional decorations.
