How to Bake Muffins
Don’t open your oven door until your muffins have started to brown.
To test if they’re done, use a cake tester or insert a wooden pick in the center of the muffins. Don’t insert a tester or wooden pick into moist ingredients like jam or jelly. If your tester comes out clean, your muffins are ready.
Remove the liners while the muffins are still warm.
