Step 1: Preheat the oven
Preheat the oven to 375°F (190°C). Prepare cookie sheets with parchment paper or a suitable baking liner if desired.
Step 2: Cream the butter and sugars
Add the softened butter, granulated sugar, and brown sugar to the bowl of a stand mixer.
Cream together until the mixture is smooth, light, and well combined.
Step 3: Add the eggs and vanilla
Add the eggs and vanilla extract.
Continue mixing until the mixture becomes fluffy and evenly combined. Scrape down the sides and bottom of the bowl as necessary.
Step 4: Add the baking soda and salt
Mix in the baking soda and salt until evenly distributed.
Step 5: Add the flour
Add the all-purpose flour gradually, mixing between additions.
Continue until all the flour has been incorporated and a soft cookie dough forms. Avoid excessive mixing once the flour disappears into the dough.
Step 6: Divide the dough
Separate the cookie dough into three equal portions.
Leave one portion its natural pale cookie-dough color.
Step 7: Color the dough
Add orange food coloring to the second portion and gently mix until you reach the desired orange shade.
Color the third portion brown.
For halal-friendly Harvest Marble Chocolate Chip Cookies, use food colorings made without alcohol or other unsuitable ingredients.
Step 8: Add the chocolate chips
Divide the chocolate chips among all three portions of dough.
Gently fold them into the natural, orange, and brown dough until evenly distributed.
Step 9: Create the marble cookies
Take small pieces of each of the three dough colors and bring them together to form a 2-ounce cookie dough ball.
Gently shape the pieces together without thoroughly kneading the colors into one another. Keeping the colors distinct creates the best marble pattern.
Step 10: Shape on the cookie sheet
Arrange the cookie dough balls on the prepared cookie sheet, leaving enough room between them to spread.
Gently press each ball down slightly.
Step 11: Bake
Bake at 375°F (190°C) for 8–10 minutes, or until the edges are lightly golden.
The centers may still appear slightly soft when the cookies are ready to leave the oven.
Step 12: Cool
Allow the cookies to rest on the baking sheet for several minutes before transferring them to a wire rack.
Let them cool until the centers have set, then serve
