These vibrant sugar cookie bars feature swirls of vanilla, cocoa, and strawberry for a marbled, nostalgic treat. Quick to make and perfect for parties, they’re soft, tender, and customizable for gluten-free or vegan diets.
For gluten-free, use a 1:1 gluten-free flour blend. For vegan, substitute butter with vegan margarine, eggs with flaxseed eggs, and milk with non-dairy milk. Swirl gently for distinct ribbons; overmixing will muddy the colors. Bars stay soft for days and freeze well for up to 2 months.
