Another great way to cut calories is to add a can of pumpkin to a box of cake mix instead of the oil, eggs and water. I've made them with both spice cake mix and chocolate. You can't really taste the pumpkin in the chocolate muffins!
You can read about these muffins on my other blog (My Romantic Home). Just click on these links: Diet friendly Pumpkin Spice Muffins or Diet Friendly Chocolate Muffins.
I think I may make some of these this weekend and freeze them! Some mornings it's nice to treat yourself with a muffin with your coffee!
