Last week at happy hour, a coworker of mine noticed me lugging around a birthday cake for my next stop of the evening and lamented that I never made anything for him. Lucky for him, these jabs work on me if I know you. Put on a little puss and I am usually suckered into making something. Especially if the thing I just made (i.e. aforementioned birthday cake) was a disappointment and I feel the need to redeem myself. So I asked him what he wanted and he made a specific request: dark chocolate cupcakes with raspberry filling.
Ooh. Filling.
I had some leftover homemade raspberry coulis(which is even more fun to write than "I had some leftover homemade stock") from making the filling for another cake. And given that the coulis demands so much of a poor girl's time running the berries through a sieve or a food mill to remove the seeds, it's a terrible shame to let any go to waste.
The cake is a devil's food recipe with sour cream I use a lot, with a fudgy pan frosting. I love frostings with cooked sugar (i.e. not powdered sugar) and this one was adapted from an Anne Byrd recipe.
The recipe for the coulis was the raspberry sauce and puree recipe from The Cake Bible. I have used it before with great success as a filling for a dark chocolate cake, a sauce to serve with the cake and to flavor buttercream. Rose Levy Beranbaum's technique of reducing the juice drained off the berries, pureeing the pulp and heightening the flavor with fresh lemon juice results in a very intense raspberry flavor. The filling tastes so fresh and looks so beautiful I would gladly lick it off cardboard, so thank you Rose for making me look good!
I had about a cup of coulis and it was the perfect amount to fill 22 cupcakes. Since I couldn't find a succinct description of how to fill cupcakes after a perfunctory search, and it is a question I am most often asked, the filling is put into cupcake after it has baked with a pastry bag fitted with a pastry tip (a bismark tip is ideal but you can use any large round tip).
You can see a better shot of the filling here. Altough I probably got overzealous with applying pressure wile getting the filling into the cupcake at right, it does give a peek of the bright pink puree inside.
The coworker? He ate four of them.
