Did you do a double take when you read black bean flour?

I know I certainly would!

Get ready to see a lot of unusual ingredients in future posts now that I can mill my own flours. I was sent a Mockmill that simply attaches to my Kitchen Aid. It mills anything into flour, even hard dry black beans!

The Mockmill also works with AEG, Electrolux, and Kenmore mixers.

This cake is incredibly moist. The black bean flour adds not only to this moistness, but it also adds a protein punch to this cake. One of the things I love about using my Mockmill is that I have full control of my flour. There is NO worry about cross contamination during the grinding process at a warehouse.

Black Beans in the Mockmill

(*Please note I was given this Mockmill to review. All opinions and wildly happy excitement are my own, because this is the coolest kitchen toy ever!)

If you look at the Mockmill photo above, do you see the line of dots? Those are the adjustments so you can make the flour as fine as you like! There are so many settings ranging from course, to super fine. This is what bean flour looks like when freshly milled.

You remove a screw, remove the silver circle that covers the attachment hole, then push in the Mockmill. Put the screw back in to hold it in place and it is ready to use.

The Flour Power book that comes with this talks a lot about the importance of getting nutrients back into your baking and I was really surprised how much processing goes into commercially bought flours.



(*Note, grains in this photo are not the gluten free grains you will receive. I just wanted to show you a picture of what it all looks like.)

Clean up is simple because you don’t use water to clean this. Just dust off the internal surfaces and it is clean and ready for the next use!

If you have been following my blog for a while, you know my kids like to be involved in my baking. This cake is gluten free, but if you see in my pictures, my kids insisted on butterscotch chips. Any chip is optional in this recipe.

  1. Haha, yes!!! O my gosh, LOVE the black bean flour (so much cheaper this way!)

  2. I assume you are using a small baking pan, but what size is it? Would my food processor grind the beans as well? Thank you for the review. I like the Mockmill, just too expensive, even with the discount. Recipe looks good, too.

    • Hi Debbie, I would say try it in a food processor. I have never tried this, so I don’t know how fine that can grind. Would you be willing to write back and let my readers know how it turns out? Thank you so much πŸ™‚
