how long do you cook mini bundt cakes?"

As with most bake goods, the bake time will vary depending on the recipe and the equipment (your pans your oven etc). I assume you're talking about 1-cup measure mini-bundts, and in that case 20-30 minutes is a good guesstimate of the time needed. (Most tending toward the lesser 20-25 minutes in my experience) Sometimes you just have to experiment the first time you use recipe. William Sonoma has some delightful mini-bundt recipes on their website (the mini-spice bundt recipe has been a favorite first attempt recipe for beginners): <a rel="nofollow" href="http://www.williams-sonoma.com">www.williams-sonoma.com</a> (Click on the tab for 'Recipes' at the top of the page and type in mini bundt in the search page to locate these two recipes.) Most important with these beautiful pans is to grease them well. Baker's Joy is an excellent time saving product in my opinion, but the good old fashion butter and flour method works great too. Good luck and enjoy!  more
