Hi! I wanted to use the following recipe to bake a pound cake for Christmas (to use for chocolate fondue) but I don't have a bundt pan or any small pans, really. Is this something that I could bake in a 9 x 13 inch pan, or I also have 6 in and 8 in round pans. Would that be better?

This is the recipe (I found it on this site, I think it is Elaine2581's recipe)

3 sticks butter, softened
3 cups granulated sugar
1/8 teaspoon salt
1 (8 oz.) package cream cheese, softened
6 eggs
3 cups sifted cake flour
2 teaspoons vanilla

Preheat oven to 325 degrees.
Mix butter, sugar and salt until creamy. Add cream cheese and mix well. Add eggs, one at a time, alternating with the flour. Add vanilla and beat the entire mixture for 2 minutes. Pour into a Large (12-cup) greased and floured tube or bundt cake pan, Bake for 90 minutes.
Remove from oven and allow to cool in pan 10-15 minutes before inverting onto a cooling rack to cool completely.

Note: It is not a mistake that no milk or other liquid is included. It is a thick, rich batter and will overflow and make a mess in your oven if you use only a 10-inch bundt pan. I learned from experience and just cook some of the batter in a small casserole dish or 6-inch pan if I choose to use one of my fancy bundt pans that holds less than 12 cups.

Just check that a 9x13 pan can hold 12 cups - I am not sure about the volume there, I don't use cup measurements. But if the batter fits I can't see why you wouldn't be able to use it. Maybe put a flower nail in the middle of the pan to help cook the centre.
It will mean you can cut your cake into neat little squares (not sure how you would do that if you used the round tins) for your fondue.

OK I just answered my own question, and confirmed I am rubbish at using cups for measuring! According to Metria's cake calculator thingy, 9x13 needs 7 cups of batter to make 1 layer:

So, if you use the full recipe you posted, it will overflow, as she warns at the end of the method! Maybe just halve the recipe?
