I want to use one of my cake recipes and make a bundt out of it. But I don't know how much batter would be enough to fill it. Any help would be great! Thanks!

You can use water to measure how many cups it takes to fill it.

I never would have thought of that! Thanky very much

Just thought - where do I fill up to so it doesn't flow over the sides when baking?

There are various sizes of bundt pans, but the most common one is a "one mix" pan. Most cakes mixes make 4-6 cups of batter. The homemade recipe I use makes 6 cups of batter and it works very well in a bundt pan. Remember that you will need to bake it longer, probably 45-50 minutes.

Thanks i'll just measure my batter first
