There is something about winter that makes me crave spice cake. Even while the cake is baking, I feel comforted – the whole house fills with a warm and comforting smell.

I decided to make a carrot cake and I love the idea of sneaking in more healthy ingredients  – so why not lentils? I love lentils because they are just as packed with nutrients as beans, but are so much easier to use because no soaking, etc., required.

Using lentils in this cake gives the cake a rich, moist texture without tons of oil or butter being used.

So, if you have some leftover lentils after making soup, try this delicious way to use up your leftovers.  And make your house smell good all day!
