Bundt Pan question
Question:
How do I know how many ‘Cups’ my bundt cake pan holds?
Answer:
Great Question!!
First, check your recipe size
A typical cake recipe calls for a 9" x 13" pan, two 9" rounds, three 8" rounds, or 2 dozen cupcakes. This size recipe makes about 6 cups of batter, and will fit in most Bundt pans.
Next, check your pan's capacity
You might have a 10-cup Bundt pan, or a 12-cup, or something in between. Bundt pans can vary in width and depth, too. Rather than try to match volume to dimensions to capacity, simply measure your pan's bakeable capacity by pouring water to within 1 1/4" of the top rim. Measure the water; this is your pan's true baking capacity.
Finally, match recipe to pan
10-cup Bundt pan
A typical cake recipe — one calling for a 9" x 13" pan, two 9" round pans, or three 8" round pans — will fit in a 10-cup bundt pan, which has a bakeable capacity of about 6 cups. Fill the pan to within about 1 1/4" of the top rim.
A smaller pan
If you're making a typical cake recipe in a smaller Bundt pan, one whose bakeable capacity is less than 6 cups, you'll have excess batter. Again, only fill the pan to within about 1 1/4" of the top rim; use any leftover batter to make cupcakes.
A larger pan
If you're making a typical cake recipe in a larger Bundt pan, the finished cake will be smaller, though still retain its pretty design. The cake may take slightly less time to bake; start checking 15 minutes before the end of the minimum baking time.
