Baking a cake on a random weeknight , especially when living in a small household, is a rare occasion. However, craving a slice of cake on a Wednesday night is not that uncommon. What to do? Freeze slices of cake, of course. Then you're only a few minutes away from a slice any night of the week.
A few cautionary items before throwing that birthday cake in the freezer: frosting can get weird when thawed out. Not all frosting will weep and separate, but steer clear of those made with egg whites and cream. Basically, the more butter, the better. If you're determined to give the frosting a shot, freeze it in small portions before adding to the cake. When defrosting, give it a good stir before topping your cake slice. Some frostings like cream cheese and buttercream will hold up just fine. Be sure to allow the cake to freeze before packaging to keep the frosting intact — just place the slices on a sheet pan in your freezer until solid, then wrap with plastic wrap as usual.
I love freezing my almond buttermilk cake. I wrap each slice tightly in plastic wrap and then either place in a heavy freezer bag or wrap with aluminum foil. When I'm ready for a slice, I pull one out of the freezer and either let it thaw on the countertop or pop it in the toaster oven wrapped in foil to speed up the process. Dusted with a little powdered sugar it's as good as fresh baked!
Choose sturdy, moist cakes for freezing so they'll hold up through the process. Pound cake, carrot cake and dense chocolate cake all freeze well.

I love this idea because I love cake...
This is a nice idea.
I have a very basic, simple recipe for cake that can be varied any way you like. It's so simple and quick, with such ordinary ingredients, that you can mix it all together in a few minutes, leave it in the oven while you're cooking dinner, and have it ready for dessert after. It's not fancy at all, but you can add spices or chocolate chips, or coconut, of fruit. Or frosting or powdered sugar...
If you are going to eat the cake within 2 weeks, you don't have to freeze the frosting. Place the frosting in an airtight container and put it in the fridge. It's not going to get stale like the cake will if you put cake in the fridge. Sitting in the fridge will produce fewer negative effects on frosting than freezing frosting would.
What I would do is put the frosting in a pastry bag or a plastic ziploc bag with a corner snipped off. Then place the pastry bag or plastic bag in a larger bag. When you defrost your cake, squeeze a bit of frosting out. That's less messy than having the frosting in an airtight container with a lid, then having to get out a spatula, etc.
Almond buttermilk cake! Looks and sounds amazing! Lovely presentation!
What about cupcakes? Do these freeze well? I'm not a huge cake-y person, but I love cupcakes. Also, what about cheesecake?
