Easy Sweet Potato Cookies

Sweet potatoes are about as humble as you can get in a vegetable, aside from the the classic russet potato. As versatile as russet potatoes can be, sweet potatoes can beat them out in terms of versatility. Sweet potato pie, candied and desserts, we’re all over it like kids in a candy store. Moving on over to something different this week, we’re craving something cookie-ish and of course, sweet potato-ish because tis the season for sweet potatoes.

Vietnamese cinnamon & sweet potatoes: deadly combination. But in a good deadly way.

We’re seeing them everywhere at the markets and with so many different varieties, we’ve always eating something every week that sweet potato based. We combined a few different sweet potato cookies to come up with these soft, molasses, rum-macerated-raisin, sweet potato cookies. One of us is a big fan of cake-like cookies, and the other loves to inebriate our desserts, so we both won on this cookie recipe. The combination of soft, fluffy and cake-like texture of these cookies reminds us of muffin tops. So if you’re a fan of muffin tops, these cookies are perfect for you.

It’s the sweet, caramel taste of the molasses that shines through this cookie too. Not too sweet and perfectly pillowy soft like a little cake. Our sweet potato molasses cookies are different and always a treat to share with cookie lovers.

We also used a very cool buttermilk substitute for the first time.  It is something we we never have in the fridge and we hate having to go out the the store for just one ingredient, so we tried this method and were very pleased.  For every cup of buttermilk needed, take a cup of regular milk, add a tablespoon of lemon juice, then let it sit for about 5 minutes.  Works great for most of our cooking needs.

Molasses Sweet Potato Cookie (Cake-like cookies)

These are a nice soft, cake-like molasses cookies which has a nice texture from the grated sweet potato.  If you really want to knock someone's socks off, macerate the raisins for a long time, like a couple weeks or more. 
If you don't have any buttermilk on hand, make your own.  In general, add 1 tablespoon of lemon juice to 1 cup of milk and let sit for for 5 minutes. So for this recipe, add 1/4 Tablespoon (just a bit less than 1 teaspoon - 3 teaspoons=1 tablespoon) of lemon juice to a 1/4 cup of milk, then let it sit for 5 minutes.  Perfect buttermilk substitute.
