Since these muffins are fat and dairy-free, they will have a bigger chance of sticking to the muffin liners. Our first recommendation is to use silicone or non-stick muffin papers. Cheaper muffin papers don’t release as well. You can line the muffin tin with liners and then give them a quick spray with non-stick cooking spray or just grease the muffin pan without papers. Lastly, let your banana blueberry muffins cool before removing the liner. The muffins often shrink and will contract from the liner.
