Try Adding Cornstarch

To make even lighter cakes, and to achieve an even lighter crumb, you can add a small amount (about ¼ cup/30 g per 2 cups/234 g of the blend) of cornstarch to your Cake & Muffin Blend for heavenly results. Professional bakers have used this trick for years, and it works perfectly in gluten-free baking as well. The cornstarch, especially in the case of oil-based cakes, helps create larger cake crumbs, resulting in a moist yet crumbly confection.
