Looking for a yummy alternative to banana bread for using up those overripe bananas lingering on your counter? Give this easy Instant Pot Flourless Banana Oat Cake a try.
This cake reminds me of a cross between banana bread and one of my favorite homemade treats—baked oatmeal. And it’s equally good as dessert, with a little scoop of low-fat vanilla ice cream or frozen yogurt, as it is for breakfast, or brunch, with a dollop of Greek yogurt and some fresh berries.
Naturally sweetened and low calorie, this banana cake bakes up dense and moist. And because you cook it in an Instant Pot, you don’t have to turn on your oven and heat the entire kitchen—a blessing for those of us living in warmer climates.

How to Make Instant Pot Banana Oat Cake, Step by Step
Step 1: Gather and prepare all ingredients.
Ready to make the cake
Step 2: Cut two strips of parchment paper and place in 7-inch round baking pan making a cross, set aside. This will allow you to easily remove the cake from the pan.
Place crisscross parchment strips in pan
Step 3: Mash the banana in a mixing bowl. Stir in the almond butter, sweetener, eggs, baking soda, cinnamon and salt until mixture is thoroughly combined. Stir in the oats until completed coated.

Step 4: Pour the mixture into the prepared pan and smooth out the top, as necessary.
Ready to bake the cake
Step 5: Add the trivet to the Instant Pot followed by 1 cup water. Place baking pan on trivet and cover with silicone lid (if available, included with Instant Pot Bake Set), or parchment paper or an upside-down plate. Covering the pan will prevent any moisture from dripping into the cake as it bakes.

Step 6: Place the lid on the Instant Pot moving the steam release valve to the Sealing position. Cook on HIGH pressure for 40 minutes.
Cook cake for 40 minutes on high pressure
Step 7: Once the cooking time is finished, allow the pressure to release naturally for 10 minutes. After 10 minutes of natural pressure release, move the steam release valve to Venting position and allow any remaining steam to release (being careful to not get burned).
Step 8: After pressure is released and float valve drops, unlock and remove the lid. Carefully lift the pan (or trivet holding the pan) and remove from the pot (use oven mitts as necessary to prevent any burns).
Step 9: Place the cake on a wire rack and remove the silicone lid (or parchment or upside-down plate) being careful to not drip any condensation onto cake. Allow cake to cool completely, at least 30 minutes.

Step 10: Run a thin sharp knife around the side of cake to loosen it from the pan. Using the parchment strips, lift the cake from the pan and place on serving plate or cutting board (affiliate link).
Cutting the cake into wedges
Cut the cake into 6 wedges and serve with any additional toppings (lite whipped topping, low-fat ice cream or frozen yogurt, nonfat Greek yogurt, berries, etc.)
Step 11: Store any leftover cake in an airtight container.

Recipe Notes
Use your favorite zero-calorie sweetener. Some of the more popular alternatives are Swerve, Splenda, Equal, Stevia and Monkfruit. I haven’t tried Swerve yet, but I really like using Lankato Monkfruit sweetener right now.
To ensure this cake is gluten-free, be sure to use oats that are labeled gluten-free.
A banana with more brown spots will also be sweeter than a banana without spots and it will be softer and easier to mash too.
Serving Suggestions
Enjoy your flourless cake at room temperature, chilled from the refrigerator, or lightly warmed in the microwave (affiliate link).
Serve this a la mode for dessert with a scoop of low-fat ice cream or frozen yogurt.
Or enjoy it at breakfast, or brunch, with some nonfat Greek yogurt and fresh berries—sliced strawberries, blueberries, blackberries and raspberries would all be delicious.
