Set your oven to 350°F (175°C) and prep a baking tray with parchment paper so nothing sticks.

In a big mixing bowl, whip the softened butter, white sugar, and brown sugar until it’s smooth and fluffy. Mix in the eggs one by one, then add the vanilla extract.

Gently stir the dry mix into the wet mixture a bit at a time. Blend just enough until it all comes together.

Separate the dough into four parts. Use the gel food dyes to color each part in pastel shades of purple, yellow, pink, and blue. Mix lightly to keep the colors soft.

Pinch bits from each colored dough, squish them gently to get a marbled look, and roll into balls. Flatten them a little on the parchment-lined sheet, then sprinkle some chocolate chips over the top.

Bake for about 10–12 minutes until the edges look slightly golden. Leave them on the tray for 5 minutes to set up before moving them to a cooling rack.
