A light panna cotta is a great way to end a romantic evening, like Valentine's Day. It is easy to prepare and can be set up in advance, which leaves you free to worry about other aspects of your night. When discussing panna cotta, "light" usually refers to the delicate texture and melt-in-your mouth appeal of the lightly gelled dessert, not necessarily to the fat or calorie content of the treat. There is nothing wrong with a little indulgence, but it's nice when a dessert that is light in texture is also light in the stomach, so I have made this panna cotta a little more figure-friendly by using yogurt and light cream (half and half) in place of the all-cream standard. I added some berries for color and a little bit of sugar for sweetness. The result is a dessert with the appealing texture of panna cotta, far less fat and the slight tang of yogurt.

The original pound cake got its name from the fact that it contained a pound of each of its basic ingredients: butter, sugar, flour and eggs. The average pound cake these days tends to be a bit more refined, using some sort of leavening agent in addition to eggs and often incorporating additional ingredients, such as vanilla, sour cream, heavy cream or even chocolate.

Pound cake, needless to say, is not a low fat food. It is dense, tender, buttery and something that is best eaten in small portions if you are watching what you eat. Of course, pound cake tastes so good that it can be hard to stop with just one slice. This recipe produces a lightened pound cake that is almost entirely fat free, so you don't have to stop with a mere sliver.

Hanukkah is known as the "festival of lights" and is a holiday in which oil has a special meaning. To put it very, very briefly, Hanukkah celebrates a miraculous occurrence where one night's worth of oil burned for eight. There is a lot of oil used in foods that are served for this holiday and much of it is used for frying. The two most well-know Hanukkah staples are sufganiyah (jelly-filled donuts) and latkes, or potato pancakes. As good as these two foods are, health-conscious holiday revelers don't always want to completely blow their diet with a meal of entirely fried foods, nor do they want to restrict themselves to only a few bites of this holiday favorite. Recognizing the health conscious, many people who host Hanukkah parties plan to serve baked latkes, as well as fried.

Baked latkes are often undercooked and not nearly as crispy as fried ones, but this recipe makes an excellent stand-in that is better than most. A minimal amount of oil is still used to grease the baking sheets, and the latkes turn out to be very crispy and very satisfying - with far less fat than ordinary latkes. They have a good potato flavor and, because they are thin, are not undercooked in the center.

Replacing the fat in baked goods is something that we have done a few times now, but for some people fat is not the issue that they want to tackle - it's sugar. Baking without sugar is much harder than baking without fat because fats contribute to the texture of the finished product, but not as much to the flavor. Granted, a buttery flavor can be nice, but I have had fat free cookies (made with applesauce) on numerous occasions that have tasted quite good, even if they are lacking in the texture department.

When Alanna sent me a note to let me know about a Lifehacker post on making low-fat cupcakes, I knew I would have to give it a try out of sheer curiosity. After all, Lifehacker is not exactly a food oriented site and to take a break from their regularly scheduled content to mention cooking seemed to be a sign that their technique was worth trying. Notice that I said technique and not recipe.

These light cupcakes are sort of a food hack (or a diet hack) using two ingredients: cake mix and diet soda. If you're not curious, or are so put off by the ingredients that you don't want to hear how the cupcakes turned out, you may as well stop now. Otherwise, read on...

While trying out light recipes is fun for those who love to bake, not to mention a satisfying way to know that you're not going to over-do the indulgences because the desserts are lighter/healthier than "normal" recipes, sometimes a boxed mix is convenient. For example, if you are at the home of a friend who owns no baking ingredients whatsoever, a mix with all the flour, sugar, leaveners and flavorings you need can come in handy. Mixes are also reliable, and even if you have a fool-proof favorite chocolate cake recipe, sometimes it's just easy to have a backup on hand.

The final reason to use a mix is that some of them taste good. And this is especially good to keep in mind when the good-tasting ones turn out to be fat free.

While reducing the fat in baking gets easier with time, especially after you practice with a few recipes and accept the possibility of failing every once in a while, you have to wonder how far you can push the limits. While there are fat free cakes, like angel food, the texture in those is decidedly different from that of a traditional cake, which you expect to be moist and tender, not airy. After much testing, cookbook author Sarah Philips, came up with a whole book of all-natural, low fat recipes (The Healthy Oven Baking Book). This cake is a variation on one of the recipes from that book - and it has almost no fat.

Last week we looked at how to make some low fat oatmeal cookies that were just as good as their full-fat counterparts – not to mention that they are better for you. This week, instead of choosing a recipe that needed to have something replaced, as the applesauce stood in for some of the butter in the cookies, the recipe is a cake that already has a no-added-fat base. Basically, instead of relying on a richer butter cake base, this version of pineapple upside down cake uses a sponge cake as the base.

Reducing fats in baked goods is difficult, without question. The reason that so many recipes involve copious amounts of butter and sugar is that they taste best that way. Shortbread without butter is just a cracker and a pecan pie without sugar is just a bunch of nuts. Since baking is actually more science – a delicious science - than not, each ingredient in a recipe has a role to play, so changing them can adversely effect the outcome you are trying to achieve when your real goal is to indulge without expanding your waistline.

Fats in particular are important. They are important to dieters and they are important to bakers. Light Life, which is a new feature here at Slashfood, is going to take a look at lightened and low fat recipes, as well as at some commercially avaliable products, like baking mixes.
