cupcake filling/refrigeration question

I am making cupcakes for a party today - i was planning on making vanilla cupcakes with raspberry mascarpone filling, with dark chocolate frosting... but I realized that I won't be able to refrigerate them, which I was thinking I might have to because of the mascarpone. Do you think they'd be okay at room temp for a bunch of hours? Or should I make a raspberry buttercream to fill them instead?

I'm not 100% sure... But I think you'd be ok leaving it a room temp for a few hours. Hasn't mascarpone been "cured" with citrus? This would slow the spoiling process, no?

On another note this sounds delish. Do you make your frosting? If so, could I have the recipie?!

Thanks! That's what I though too.. I was going to stiffen the filling with a little powdered sugar so it's not too runny, so the sugar should help preserve it too, no?

Here's my frosting recipe

¾ cup butter, room temperature
6 oz unsweetened chocolate, chopped
1.5 lbs powdered sugar
1/2 cup milk or so
3 teaspoons vanilla
big pinch sea salt

Melt the chocolate. Let it cool for 5 minutes. While it is cooling, beat the butter until fluffy. Add the vanilla and salt. Add in the powdered sugar a heaping tablespoon at a time, waiting for it to be incorporated before adding more (this helps the frosting to be extra fluffy). Pour in the chocolate. Add in milk as needed until it is the consistency you want.

I usually will use rum instead of milk, at least for some of it. And if I want to use milk and don't have it, I will use a mix of fat free half and half and a splash of water.

I think this time I will use a mix of raspberry liquor and rum.

ETA: I also will often add some cocoa powder too, to make it extra chocolaty and have the dark chocolate flavor.

Ohhh thank you - sounds amazing!


I don't think adding the powdered sugar will make a difference in the preservation. I'm sure they'll be fantastic!!
