What texture does Wayne Thiebaud use in his work?

Wayne Thiebaud is famous for painting still lifes that showcase the textures of the objects in the painting, including cakes, chocolates, and other objects. According to the site from the National Gallery of Art (see the link below), Thiebaud uses paint in ways that re-create the look and feel of what he is depicting. For example, in the painting Cakes, the artist used very thick paint to show the texture of the desserts. He uses impasto, a technique that involves the thick application of paint onto the canvas, to show texture. He also uses heavy, broad strokes. His work is known for showing the foods he paints as if they were real. For example, his frosting really looks like it has the texture of frosting on a cake.
