For the test, I chose to whip up two half batches of Vanishing Oatmeal Raisin Cookies – one using butter, the other using ICBINB sticks.
I set up two bowls, each labeled with the fat of choice.

Next, I creamed the sugars and fats together.

Then, I added the eggs and mixed until well combined.

This is when I noticed the first major difference – the texture of the ICBINB mixture was much softer and looser.

Then, I added the dry ingredients to the wet ingredients.

Next, I lined two half-sheet pans with parchment paper and marked the underside of each sheet with either a B or I to indicate which batch was which.

Then, using a large spoon, I dropped the dough onto the appropriate pans. The ICBINB dough was significantly stiffer.

Between batches, I switched up which versions cooked on which racks in the oven. When each batch came out, I noticed that the butter-based cookies consistently spread more and browned more.

In the side-by-side taste comparison, the ICBINB version was preferred 6 out of 10 times. My taste testers commented that the ICBINB cookies were moister and tasted a bit sweeter. Truth be told, I still preferred the butter version, even though I was outnumbered. But, I wouldn't turn an ICBINB cookie down. If I weren't tasting them side-by-side, I don't think I'd notice a difference.

So, in the end, what does this mean? Well, if you're watching your saturated fat intake, the ICBINB Cooking & Baking sticks might be a better option for you and you don't have to sacrifice taste. That's good in my book.

On a separate note, it's my blogiversary! A whole year ago, this little blog was born. It's been a lot of fun and I'm excited about the year to come!
