Filling a bundt pan with cake can be a fun baking project, but it’s important to know how much cake mix you need to fully fill the pan. Buying too little cake mix can lead to a half-filled bundt that won’t properly bake, while buying too much is wasteful. So how do you determine the right amount of cake mix boxes to buy? There are a few easy steps to figure it out.
Calculate the Volume of Your Bundt Pan
The first step is to calculate the volume of your bundt pan. Bundt pans come in many different sizes, so you’ll need to take out a measuring tape and do some quick math to find out the volume of your specific pan.
To calculate volume, you need the measurements of three dimensions – height, diameter (the distance across the widest part of the pan), and center tube diameter. Measure the inside of the pan across these three dimensions in inches. Once you have the measurements, use the following formula to calculate volume:
Volume = π x (Radius)^2 x Height – π x (Center Tube Radius)^2 x Height
Where π is approximately 3.14, radius is half of the pan diameter, and height is the vertical distance from the top of the pan to the bottom. For example, if your pan is 4 inches tall with an 8 inch diameter and a 2 inch center tube, the calculations would be:
Volume = 3.14 x (8/2)^2 x 4 – 3.14 x (2/2)^2 x 4
Volume = 3.14 x 16 x 4 – 3.14 x 4 x 4
Volume = 201.12 cubic inches
This will give you the total volume of cake batter the bundt pan can hold.
Determine Cake Mix Box Volume
Next, you’ll need to know the volume of cake that each box of cake mix will make. Check the back of the cake mix box to find out how many cups the mix makes once prepared. Most mixes make around 22-24 cups of batter.
To calculate the volume of the prepared cake mix, multiply the number of cups by 16. This is because 1 cup is equivalent to 16 cubic inches. So for example:
22 cups x 16 cubic inches = 352 cubic inches
24 cups x 16 cubic inches = 384 cubic inches
This tells you how much total cake volume each box of mix provides.
Calculate Number of Boxes Needed
Now you can calculate the number of cake mix boxes needed to fill your bundt pan. Take the total volume of your pan and divide it by the volume of cake batter each box makes:
Bundt Pan Volume / Cake Mix Box Volume = Number of Boxes Needed
As an example, if your bundt pan holds 201 cubic inches of volume, and the cake mix makes 22 cups (352 cubic inches), the math would be:
201 cu in / 352 cu in = 0.57 boxes
So in this case, you would need 1 box of cake mix to fill the bundt pan.
In summary, the steps are:
- Calculate volume of your bundt pan
- Determine volume of cake each mix box makes
- Divide bundt pan volume by cake mix volume to get number of boxes needed
Making a test batch can help you determine exactly how much batter to use for your specific pan. But this gives you a good estimate to start with so you can buy the right amount of cake mix boxes.
Tips for Filling Your Bundt Pan
Once you know how many cake mix boxes to buy, here are some tips for filling your bundt pan:
- Use butter or non-stick spray to grease the pan well, getting into all the crevices. This prevents sticking.
- Only fill the pan 2/3 to 3/4 full with batter. Overfilling can cause spillover and uneven baking.
- Tap the pan on the countertop to release any air bubbles after pouring in batter.
- Use a spatula or knife to smooth the top of the batter evenly.
- Bake at the temperature and time recommended on the cake mix box.
- Check for doneness by inserting a toothpick – it should come out clean when the cake is ready.
- Cool the bundt completely before inverting onto a plate or rack.
Properly greasing, filling, and baking the bundt pan will result in a beautifully shaped cake with a hole in the center. The right amount of cake mix for the pan size is crucial.
Frequently Asked Questions
What size bundt pan is most common?
The most common bundt pan sizes are 9-inch, 10-inch, and 12-inch diameters. Nordic Ware is one of the major bundt pan brands and many of their classic pans are around 10 or 12 inches.
How much batter should you use to fill a bundt pan?
As a general rule, you should fill a bundt pan about 2/3 to 3/4 full with cake batter. Going above 3/4 can cause overflow. Using too little batter may lead to an unevenly baked cake.
Can I double a cake mix recipe for a bundt pan?
You can safely double most cake mixes to make a bigger bundt cake. Just ensure your pan is large enough to hold the extra batter without overflowing. Also extend the baking time 10-15 minutes for a double batch.
How do I get a bundt cake out of the pan neatly?
To remove a bundt cake cleanly, first be sure to grease and flour the pan well prior to baking. After cooling completely, run a knife around the edges to loosen. Place a plate or rack over the pan and carefully invert. Lightly tap the bottom if needed to release the cake.
What is the best cake mix for bundt cakes?
Dense cake mixes like pound cake, vanilla, and spice cake work extremely well for bundt cakes. Stay away from mixes that need oil instead of butter or eggs. The richer the batter, the better a mix will turn out baked in a bundt.
Bundt Cake Mix Recipe
This simple vanilla bundt cake recipe turns out perfect using just a box of cake mix:
Ingredients
- 1 box white or yellow cake mix
- 1 cup water
- 3 eggs
- 1/3 cup vegetable oil

- In a large bowl, combine cake mix, water, eggs, oil, and vanilla. Beat with electric mixer on medium speed for 2 minutes until completely blended and smooth.
- Pour batter into prepared bundt pan, filling 2/3 to 3/4 full. Use a spatula to smooth the top evenly.
- Bake for 45-55 minutes until a toothpick inserted in center comes out clean. Check around 45 minutes to prevent overbaking.
- Allow cake to cool completely in the pan on a wire rack. Then loosen edges with a knife and invert onto the rack to release cake.
- Optional glaze: Whisk together 2 cups powdered sugar and 2-4 tbsp milk until smooth. Drizzle over cooled bundt cake before serving.
Common Bundt Pan Sizes
Here is a table with some of the most popular bundt pan sizes and their capacities:
| Bundt Pan Size | Cake Mix Boxes Needed |
|---|---|
| 9-inch diameter | 1 box |
| 10-inch diameter | 1.5 boxes |
| 12-inch diameter | 2 boxes |
| Giant/Texas Size | 3 boxes |
This gives you an idea of how standard bundt sizes compare to the amount of cake mix needed. Bigger pans will need more boxes of mix to fill them up and bake properly.
Bundt Cake Tips
Here are some additional tips for baking the perfect cake in a bundt pan:
