Why this recipe works?

It’s got a lovely citrus flavor with a moist tangy crumb thanks to the addition of the mashed bananas and buttermilk.

This cake isn’t fussy to make, and the flavor is outstanding!

How this recipe came to be:

This orange bundt cake with bananas and poppy seeds came about because I’ve been craving oranges like crazy this freezing cold winter, and have been purchasing navel oranges non-stop from the grocery store.

But craving oranges isn’t the only reason this incredibly delicious citrus bundt cake came about.

You see, along with all the navel oranges I’ve been craving, I’ve also been re-binge-watching the entire series (yep, all the seasons) of the Great British Bake Off which always puts me in the mood to bake like mad!

The combination of those two things led me to create this recipe for Best Orange Bundt Cake with Banana and Poppy Seeds. So if you’re ready…On your marks! Get set! BAKE!!

What is the purpose of baking with buttermilk as opposed to regular milk?

  • Buttermilk (or a buttermilk substitute) ensures a moist and tender bake by breaking down tough gluten strands in a batter.
  • Baking with buttermilk also adds a slight tartness to baked good which is very pleasant to the palate in contrast to many sweet, rich desserts.

What if you don’t have buttermilk in the fridge?

What’s that? You don’t have buttermilk in the fridge but you have all the other ingredients on hand to make this citrus pound cake! Now what?

NO PROBLEM! Did you know you can make your own buttermilk at home?

How to make homemade buttermilk:

  • Add 1 tablespoon of white or cider vinegar (lemon juice can also be used) per every cup of regular milk.
  • Stir.
  • Allow the mixture to sit for at least 5 minutes. 
  • Replaces store-bought regular buttermilk for all your favorite baking recipes.

If this cake is so moist, does it need a topping or icing? 

No, not really.

With the addition of the buttermilk and the mashed banana in the batter, a topping or icing isn’t actually necessary.

However, if you’re looking to really guild-the-lily, and take this citrus bundt cake over the top in regards to flavor and impressive presentation, then homemade orange curd (along with an orange icing glaze) is the perfect sweet and sour topping for this homebaked scratch orange cake you won’t soon forget.

  • Add the mashed banana to the butter and sugar mixture and blend to combine.
  • Add the buttermilk mixture to the mixing bowl and blend on low speed to combine.
  • Incorporate the flour mixture (by thirds) into the mixing bowl, blending after each addition.
  • Add the eggs (one at a time) into the batter blending well after each addition.

Well, I ended up making this and the curd. All came out well. The glaze is a bright pink from the blood oranges and the curd is more a deep, rich, red almost like an iced tea color because of cooking it. I'll get a pic and post it over on the Facebook page.

This cake looks so delicious. Can't wait to make it. I have a question, however. I received around 20 lbs of blood oranges I'm working my way through, or giving to friends and family, LOL and am wondering if that would be a good sub for regular oranges in this recipe. I know the color of the cake and curd will be different, but any other concerns? I'm thinking not, but just checking to be sure.

Renée

Hi, Mike! Great question and you're so lucky to have received so many blood oranges. They'll work just fine in this recipe. The only thing that may affect the taste (from the written navel orange) is that blood oranges have a slight tartness whereas navel oranges are sweeter. That said, I don't think the difference is enough to make the cake (or curd) too tart or unpalatable. I believe the blood oranges will be delicious substitution in this recipe and the color will be spectacular...especially the curd. If you remember I'd love to know how this worked out for you, so please let me know. Take care!! Renee
