Turning Out The Cake

One of the biggest tips for getting the cake to come out in one piece is to flip it at the right time. If you turn it too soon, the cake won’t be fully set yet and may have trouble supporting its own weight.

However, if you wait too long before inverting it the sugars might have cooled too much and it will stick. Use caution when handling the pan while flipping it.

Waiting 5-10 minutes to flip the cake is usually the perfect happy medium.

The cake itself starts with a butter cake mix but adds pudding mix and mashed bananas. My mom used to make Bundt cakes with pudding mix and cake mix all of the time when I was a kid.

The combination helps to give the cake more of a Bundt cake texture than just making the cake mix according the box. It is still tender and moist, but just a bit more dense than your standard cake mix cake.

Adding the bananas and cinnamon to the mix really adds to the flavor and texture. It kind of gives banana bread vibes.

The cake is great on its own. Or you can take it to the next level and serve it with some maple whipped cream or a scoop of cinnamon ice cream.

Ingredients

Makes: 10inch round

Instructions

Preheat the oven to 350℉.
Peel two of the bananas and place them in the bottom of a large mixing bowl. Using a fork, mash them until they are mostly smooth.
Add the cake mix, pudding mix, 1 teaspoon ground cinnamon, eggs, milk, and oil to the bowl with the mashed banana.
15.25 ounces butter cake mix, 3.4 ounces instant banana pudding mix, ½ cup whole milk, ⅓ cup vegetable oil, 3 large eggs
Using a hand mixer, beat until well mixed. Set aside.
Place the butter in a small bowl and microwave for a minute or until fully melted.
½ cup salted butter
Add the brown sugar and the remaining teaspoon of cinnamon to the melted butter and mix until thoroughly combined.
1 cup light brown sugar
Spray a standard bundt pan with nonstick cooking spray right before placing the brown sugar mixture in the bottom. Spread evenly.
Peel and slice the two remaining bananas. Place the banana slices in the brown sugar mixture in the bottom of the pan, covering the bottom in only one layer of bananas that slightly overlap in the middle.
Gently pour the cake batter over the top of the bananas and brown sugar. Make sure the cake batter spread to form an even layer.
Bake for 40 minutes at 350℉, or until a toothpick inserted into the middle comes out with a few moist or slightly sticky crumbs.
Remove from the oven and let rest for 5-10 minutes before gently inverting the cake onto a serving tray or large plate.
Cool completely before slicing and serving.
