Gluten Free Chocolate Fudge Bundt Cake

I’m just gonna leave this right here.  You still have time to make this gluten free chocolate fudge Bundt cake for your Valentine.  It is so easy and so decadent.  

So I might have mentioned in the past that I love Bundt pans.  I seem to have a bit of a collection going now.  Of course with the love of the pan itself comes the newfound love of Bundt cakes!  For the life of me, I don’t know why I didn’t really think anything of Bundt cakes before now.  Maybe I had a really dry slice of one once?   Idk.  I now love them so it must have something to do with how moist they are?!?!


What I’ve really fallen in love with about a Bundt cake is, for one, how easy it is to make.  Mix it all together in one bowl, pour into the Bundt pan and bake.  When it’s unmolded, it has it’s very own decoration built in.  Some of the Bundt pans are so elaborate now with their swirls (like this one), geometric shapes, crowns, rose shapes, mountains, you name it.  They don’t really need additional adornment, although a little glaze never hurt anyone.

I also love that it has a hole in the middle, and that hole for this Bundt cake is used to catch all the extra fudgy glaze.  When pouring the glaze over the top, you could put the cake on a wire rack to let the glaze drip below, but WHY WOULD YOU DO THAT?  Doesn’t everyone want more glaze pouring out from the middle?  Well, it doesn’t actually pour because it hardens somewhat, but still.  It’s extra glaze!

Of note about this cake, it’s really a large cake.  If you don’t have a large Bundt pan (10-12 cup), you may need to bake some of the cake batter in another small pan, such as an 8-inch round.  If you do this, baking time would be most likely about 25-30 minutes for the small cake.  Begin checking at about the 20-minute mark.  It would also be wise to bake this on a baking sheet to catch any drips that may occur during baking.

This chocolate fudge Bundt cake is so dense and chocolatey, it’s almost like a cross between fudge and cake.  There’s an explosion of chocolate with every bite and a big ‘ole glass of milk would be welcome to wash all that chocolatey goodness down!

What’s your favorite Bundt cake and shape?

  • Hello Kim: I’m new to GF and love all your tips and recipes. Why do you list ingredients by the gram weight instead of by the 1/2 cup or cup measure, etc. I don’t know how to convert it! Thanks.

    • Hi, Randi! Thanks for the wonderful comments! I got into weighing all my ingredients when I had to go gluten free and it’s so much easier and more accurate. If you can give me about 1/2 hour, I will go back on the gluten free fudge bundt cake and put the cup measurements as well for you. For future reference, they are pretty easy to find online, but I would suggest getting a scale (check out my shop page) because it really does make life easier. I usually list both, but for some reason on this particular recipe I only listed the grams.

      Thanks, Randi 🙂
