These mini banana bundt cakes use Greek yogurt instead of the sour cream or oil most recipes call for, which keeps them moist and tender without tasting heavy. Four very ripe bananas do the heavy lifting for sweetness and moisture, and a proper creaming step gives them real lift instead of a dense crumb. They’re small enough to feel like a treat, but easy enough to make on a Sunday evening for a week of lunches.

A Couple Things That Make a Difference in a Banana Bundt Cake

Butter temperature matters more than it sounds like it should. Softened to 65-68°F, it holds air properly when you cream it: cold enough to trap small air bubbles, warm enough to actually let them form. If it’s too soft or starts to melt, the cakes come out denser no matter how long you beat them.

The creaming step itself is worth taking seriously too. Beating the butter and sugar for a full 2-3 minutes, until it’s visibly lighter and fluffy, is what builds the air pockets that help the cake rise. It’s tempting to rush through it, but that’s really the step doing most of the work.

Once the flour goes in, less is more. Mix just until the streaks disappear. Overmixing at that stage is usually what makes banana cake turn out tough or gummy instead of tender.

And when it comes to knowing if they’re done, a toothpick with a few moist crumbs on it is what you want, not a completely clean one. The cakes keep cooking a little from residual heat once they’re out of the oven, so pulling them a touch early actually gets you the better result.

Ingredients

Dry:

• 3 cups (about 390g) all-purpose flour
• 2 teaspoons baking soda
• 1/2 teaspoon salt

Wet:

• 2 sticks (1 cup / 225g) unsalted butter, softened to 65-68°F
• 1 cup (200g) white sugar
• 1 cup (220g) packed brown sugar
• 2 teaspoons pure vanilla extract
• 2 large eggs, room temperature
• 4 very ripe bananas, mashed (420-450g, about 1 1/2-1 3/4 cups)
• 1 cup (240g) full-fat plain or vanilla Greek yogurt

For finishing:

• 2 tablespoons powdered sugar, for dusting

Instructions

1. Prep the pan and oven

Preheat the oven to 350°F (175°C). Grease a 12-cavity mini bundt pan using softened butter and a pastry brush, working into every ridge and the center tube. Dust lightly with flour and tap out the excess, especially if your pan is older or well used. This is the step that determines whether your cakes come out clean later.

2. Whisk the dry ingredients

In a medium bowl, combine the flour, baking soda, and salt. Set aside.

3. Cream the butter and sugars

Beat the softened butter with the white and brown sugar for a full 2-3 minutes, until visibly lighter in color and fluffy.

4. Add eggs, vanilla, banana, and yogurt

Beat in the vanilla and eggs until combined. Mix in the mashed banana and Greek yogurt until the batter is smooth and uniform.

5. Fold in the dry ingredients

Add the flour mixture in two additions, folding just until the streaks disappear. Stop as soon as you don’t see dry flour.

6. Fill the cavities

Fill each cavity two-thirds full. A spoon works fine, but a piping bag or a large zip-top bag with the corner snipped off makes it easier to fill cleanly without dripping batter down the ridges.

7. Bake

Bake for 20-25 minutes. Start checking at 20 minutes with a toothpick inserted at the thickest point. Pull them when the toothpick comes out with a few moist crumbs, not wet batter.

For one full-size bundt instead of minis, expect 50-60 minutes. Tent with foil after the first 30 minutes if the top is browning faster than the center is setting.

8. Cool and invert

Cool for 10 minutes in the pan, then invert. If you feel any resistance, run a thin knife or offset spatula around the edges first rather than forcing it out. Let the cakes cool completely on a wire rack before dusting, since powdered sugar dissolves into a warm cake within minutes.

9. Finish

Dust with powdered sugar just before serving.

Variations

• Glaze instead of dusting: Whisk powdered sugar with a tablespoon or two of milk, or melt butter with brown sugar for a caramel-style glaze, if you want something a little more indulgent for company.
• Add-ins: Fold in 1/2 cup chopped walnuts, pecans, or chocolate chips along with the dry ingredients.
• A little spice: A teaspoon of cinnamon in the dry ingredients gives these a warmer flavor without changing anything about the method.

Storage & Freezing

Room temperature: Airtight container, up to 3 days. Fridge: Up to a week, though the crumb is a bit better at room temp. Let refrigerated cakes come back to room temperature before serving. Freezer: These freeze really well. Wrap cooled, undusted cakes individually in plastic wrap, then store in a freezer bag for up to 3 months. Thaw at room temperature and dust with powdered sugar right before serving.

FAQ

Why did my bundt cake stick to the pan? Almost always incomplete greasing. The ridges and center tube need butter worked into every groove, not just a quick spray. Older or well-used pans do better with a flour dusting on top of the butter, too.

Can I use frozen bananas? Yes. Thaw them fully first and drain off any excess liquid before mashing, or the batter can end up too wet.

Why did my cake sink in the middle? Usually underbaking, or opening the oven door too early and letting the temperature drop before the structure sets. The toothpick test is more reliable than the clock.

Can I use sour cream instead of Greek yogurt? Yes, they swap in equal amounts. Greek yogurt adds a bit more protein and a slightly tangier flavor; sour cream gives a marginally richer crumb.

Final Thoughts

Mini banana bundt cakes look far more impressive than the effort they take. Get the butter temperature and creaming step right, don’t overmix once the flour goes in, and trust the toothpick over the clock. From there, they’re easy to make your own, freeze beautifully, and turn a few overripe bananas into something worth serving to guests.
