Last night I made :
Orange Coconut Cake
1 18 1/4-oz box Duncan Hines Orange Supreme Cake mix
1 3-oz package orange-flavored gelatin
1 cup water
1/3 cup vegetable oil
1 plus 1 teaspoon orange flavoring
1 16-oz package sour cream
1/4 cup frozen orange juice
1 12-ox package shredded coconut
2 cups sugar
1 8-oz package refrigerated whipped topping
In a large bowl combine the cake mix, gelatin, water, oil, eggs, and 1 teaspoon of the orange flavoring. Mix well, and pour into four prepared 8-inch pans. Bake according to directions on the cake mix box. Cool.
For the filling: In a bowl combine the sour cream, orange juice, coconut, sugar, and the remaining teaspoon of orange flavoring. Mix well. Reserve 1 cup of the filling for the frosting. Spread the remaining filling between the layers of the cake. Fold the topping into the reserved 1 cup of filling. Spread this on the top and sides of the cake. Refrigerate six to eight hours.
Okay, everywhere it says "orange" replace with lime - except the cake mix itself, where I used French Vanilla 'cause that's what I had on hand. The coconut was fresh. I used lime zest instead of flavoring because I had fresh key limes and fresh lime juice.
The cake came out nicely. The filling... was generous. And thin. I refrigerated it for the whole time the cake was cooling, but it never thickened. I tried to spread it on the first layer and it all ran all over the place. I scraped it up and put half of it into a second bowl and thickened it with a significant amount of powdered sugar, counting on the tartness of the limes to prevent it from being too sweet. This worked - more or less. As each layer was put on the cake, more and more of the filling oozed out (fortunately, much of it was at this point oozing into the cake itself, which wasn't bad); finally I got it frosted and we didn't refrigerate it before tasting - despite all, it's really good. And tonight, after the required refrigeration, it's AMAZINGLY GOOD. But I have a whole bowl of filling left... I don't know if this was a design flaw or if I missed something.
In any case, I'm going to try it again with another flavor of cake mix to use up the filling. Maybe chocolate.
I did not get my butt out of bed this morning and did not work out. I'm now full of cake and barbecue chicken. This is not the path to weight loss. Pbblllttt.
