Tender, buttery spongecake is filled with a light and fluffy marshmallow whip and topped with marshmallow buttercream.

Hostess Twinkies were good. I had a love hate relationship with them, to be honest.
On the one hand I hated the chemical sugary ick but on the other — well dang, who doesn't like that unique flavor and texture?
And texture is what is throwing off all the copycat recipes for Twinkie cupcakes that I have tried.
These copycat Twinkie cupcakes are as good (or better!) than the original.
Here's the deal, you can get the flavor (or close to it) but if you don't have the texture you don't have a Twinkie, in my opinion.
Twinkies are made out of sponge cakes, or they were. (a moment of silence, please).
The sponge cake gives a light, airy, almost bouncy texture that was the perfect foil to the creamy filling.
When you use a butter cake you can come close to the flavor but the tender crumb just isn't quite right.
Homemade sponge cakes are a thing of the past — people seem to be afraid to make them. Don't be. They do take a few extra steps but they aren't difficult steps and I know you can do it.
I promise you can do it.
Once you learn how to make the sponge cake you can get what is called a canoe pan and make Twinkies exactly like Hostess's if you want to.
You may not want to, these copycat twinkie cupcakes are just that good.
The filling is creamy and yummy and there is marshmallow buttercream on the top.
This was actually a little over the top for us. Even the kids took off some of the buttercream before eating it.
If I decide to make them again with frosting I am just going to put thin layer on top. These are really rich. Still, the downy folds of butter cream look nice, don't they?
When you have mastered this copycat twinkie cupcakes recipe (umm, like the very first time you make it, it's that easy) then you will be able to make all kinds of luscious sponge cakes with ease.
Everyone will be very impressed and you'll be the only one that knows how really easy it is to do.
I am always looking for unique cupcake flavors and these fall into that category.

Cake
- Separate the eggs while they are cold and then let them come to room temperature.
- Preheat the oven to 325F.
- Rinse the beater and bowl with vinegar and drain all the vinegar out.
- Add the egg whites and the cream of tartar to the bowl.
- Beat the egg whites until they make soft peaks and then begin beating ¼ cup of the sugar in one tablespoon at a time.
- Continue beating until the mixture is stiff and glossy.
- Remove the egg whites from the bowl and put them in another bowl that is very clean. Set aside.
- Beat the egg yolks with the vanilla and almond until they are thick and lemon colored.
- Beat in the remaining ¾ cup sugar very slowly, until the mixture is no longer grainy when rubbed between your fingers.

- Repeat with all of the cupcakes.
- Decorate as desired.

I wanted to love this but I honestly grew so frustrated. As a fellow baker could I beg you to go back through, add times and speeds. I bless those who commented as those answers gave me some ideas but it shouldn't be so hard! Maybe they would taste more like twinkies if I wasn't guessing at almost every step! Was a good cupcake with an intriguing buttercream. Not sure I'll try again unless she fixes recipe.
