While sopapillas (or sopaipillas) and buñuelos are made with basically the same sweet dough, they have very different textures. Sopapillas are softer, slightly chewy, and more pillowy (more like a donut) and served with a drizzle of honey, while bunuelos are thin, have a crispy exterior and light, airy interior, and are served with cinnamon sugar and piloncillo syrup.
