Hi, everyone -
I've made this recipe a few times now and thought I'd share what I've found using cocoa instead of unsweetened chocolate (that you need to melt) and using a mix of sweeteners. My latest experiment turned out with the perfect level of sweetness (IMHO!), no artificial aftertaste (tested by 3 people), and an absolutely silken texture.
When using cocoa for unsweetened chocolate, you can use 3T cocoa plus 1T oil as an equivalent to one square of unsweetened chocolate. So that would be 9T (or 1/2 cup plus 1T) cocoa plus 3T oil for this recipe.
The first time I did this, I used only about half the oil because of all the butter in the recipe. I found the final result to be too dry. The flavor was fine, but I didn't care for the texture. The next time I used the full 3T of oil (Crisco veggie oil, but any "flavorless" oil would work). This time, the texture was like a superb buttercream frosting. Absolutely wonderful.
I got the best results when I sifted the cocoa into a bowl, then added the oil and THOROUGHLY mixed the two together. This creates a kind of crumbly pasty mixture. Then I added the cocoa mixture to the butter/sweeteners in 3 or 4 steps, thoroughly mixing between each one. The cocoa I use is a 24% butterfat cocoa (high quality) that I buy in bulk from Penzey's Spices. (I don't have any affiliation with them, I just love that company. Great products and prices. Check them out at
penzeys.com .) I think you can also get this high-quality cocoa from
King Arthur Flour .
For the sweeteners, I had found that the artificial sweetener aftertaste was too strong for me with the original recipe. I'm very happy with the flavor (very natural) of the latest experiment which used:
3/4 C Splenda
15 packets Equal
1.5T Sugar (Yes, real sugar. I figured with all the maltodextrin and dextrose used in the Splenda and Equal, that 1.5T of sugar wasn't going to make much of a difference in the level of high-glycemic carbs.)
Note: I also paid very close attention to making sure the butter/sweeteners were thoroughly creamed together. This is not just a step of "mixing" the two together. They need to be "creamed" to make sure that each grain of sweetener is fully coated with fats. You will notice that the longer you beat the butter/sweeteners together, the lighter in color the mixture gets. I think I beat mine for 2 -2.5 minutes and frequently scraped down the bowl.
And, for what it's worth, I also beat the mixture for about 5 minutes after each egg is added. What I look for is to see if the color of the mixture is continuing to change as I beat it. Whenever I stir down the bowl, I keep a little of the mixture on the spoon. Then I beat the mixture some more, and if the color/texture of the mixture is continuing to improve after a minute or so (compared to the "sample" I kept on the spoon), then I know that I'm not wasting my time. (Remember that the process of "beating" the mixture actually changes the mixture's structure. It does this by forcing the proteins and fats and sugars to become more and more intimately bound. The clumps of protein molecules get broken up and emulsified with the broken clumps of fat molecules which then wrap around the sugar molecules. The smaller these tiny "clumps" get, the smoother and lighter the texture will be.)
So, that's my version of this wonderful contribution (THANK YOU Azure!). I realize everyone's taste is different, so sweetness and aftertaste "requirements" may be different for you. (BTW, I used a mix of salted/unsalted butter, and I reduced the vanilla extract to about 1/2tsp.) Wow, this turned out longer than I thought. Sorry!
