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.

The step-by-step photo instructions for making orange bundt cake:

• Preheat the oven to 350-degrees.
• Add the buttermilk into a medium bowl.
• OR (if making homemade buttermilk) stir two tablespoons of vinegar into 2 cups of milk. Set aside.
• Add the zest of two oranges to the buttermilk along with fresh orange juice, and orange extract (optional).
• Stir well. 

• Place two sticks of softened butter in the bowl of a stand mixer and cream together with the granulated sugar using the paddle attachment.

• Mash one overly ripe banana and blend it with the creamed butter and sugar mixture.

• Add the buttermilk and orange zest mixture to the bowl and blend until completely combined.
• In a large bowl, whisk together the flour, baking powder, baking soda, and salt.
• Working in batches, add the dry ingredients into the wet ingredients in the mixing bowl until all the flour has been incorporated.
• Stir the poppy seeds into the batter and blend to combine.

• Incorporate the eggs, one at a time, into the batter blending well after each addition.
• Prepare a bundt pan by spraying liberally with baking spray.
• Pour the cake batter into the prepared bundt pan.

• Place the bundt pan on a baking sheet and bake in a preheated oven for 75-90 minutes, or until a toothpick inserted in the center comes out clean.
• Allow the cake to cool on a baking rack for 30 minutes, and then invert the cake out onto a cake plate to cool completely.

• To make the orange glaze, mix the confectioners sugar with fresh orange juice.
• Whisk until smooth and creamy.
• Top the cake with fresh orange zest while the icing still wet.
• Serve at room temperature.
• Spoon homemade orange curd over cake slices before serving, if desired.
