The Ultimate Instant Pot Chocolate Cake: Moist, Easy & Irresistibly Decadent
For a long time, the idea of baking a cake in an Instant Pot seemed counterintuitive. My Instant Pot was for quick dinners, not delicate desserts. I honestly didn’t see the point, convinced it would take just as long, if not longer, than a traditional oven-baked cake. However, after repeatedly hearing about how the unique steam environment of a pressure cooker creates cakes that are unbelievably moist and tender, and finding myself in a bit of a baking rut, I finally decided to put my skepticism aside and give this Instant Pot Chocolate Cake a try. The results were truly surprising and absolutely delightful!
Why Bake Cake in an Instant Pot? The Secret to Unrivaled Moisture
The magic behind the Instant Pot’s ability to produce incredibly moist cakes lies in its pressure cooking method. Unlike an oven, which bakes with dry heat, the Instant Pot uses steam. This sealed, high-pressure, moist environment prevents the cake from drying out, ensuring every crumb is tender and saturated with flavor. The steam helps to gently cook the cake from all sides, leading to a consistently moist texture that’s hard to achieve in a conventional oven. While the active cooking time might be comparable to, or even slightly longer than, oven baking for this particular recipe, the hands-off approach and the superior moisture payoff make it a winning choice. Plus, on a hot day, keeping the oven off means a cooler kitchen, which is always a bonus!
A “Dump and Stir” Dream: Effortless Chocolate Cake Batter
Beyond the impressive moisture factor, what makes this Instant Pot Chocolate Cake truly stand out is its incredible simplicity. This isn’t one of those recipes that requires an arsenal of baking skills or even a stand mixer. It’s a true “dump and stir” cake, reminiscent of the beloved Chocolate Crazy Cake (or Wacky Cake). You literally just combine the dry ingredients, pour in the liquid mixture, and stir until everything is well-blended. There’s no creaming butter and sugar, no alternating wet and dry ingredients, and absolutely no mixer required for the cake batter itself. This makes it an ideal recipe for beginner bakers, kids helping in the kitchen, or anyone looking for a quick and easy dessert solution without a lot of fuss. It streamlines the baking process, proving that delicious results don’t always require complex techniques.
Crafting the Perfect Chocolate Frosting (and Mixer-Free Alternatives)
While the cake itself is remarkably simple, the accompanying frosting does require a mixer to achieve its wonderfully creamy, light texture. This is my tried-and-true chocolate buttercream frosting, scaled down to a perfect one-third portion that’s just right for this smaller cake. It’s made with natural cocoa powder, giving it a deep, rich chocolate flavor that complements the moist cake beautifully. However, if you’re determined to keep this recipe entirely mixer-free, there are excellent alternatives. A simple chocolate ganache, made by pouring hot cream over chocolate chips and stirring until smooth, offers a glossy, rich topping. Alternatively, a quick chocolate glaze, created by whisking powdered sugar with a little cocoa powder and milk, provides a sweet, thin coating. I might just try one of these mixer-free options next time, as I thoroughly enjoyed the overall flow of this recipe and the sheer fun of using the Instant Pot for baking. The small size of the cake is also a huge plus, making it perfect for smaller households or when you crave a homemade treat without an abundance of leftovers.
Recipe Inspiration & Customization: Making it Your Own (and Vegan!)
This delightful Instant Pot Chocolate Cake recipe is inspired by a hazelnut version found in Ivy Manning’s fantastic Instant Pot Italian cookbook. Her original recipe is a double batch, made in an 8-inch springform pan, and incorporates hazelnuts and Frangelico liqueur for a distinct flavor profile. For this adaptation, I opted for a simpler, more classic chocolate cake experience, finding it perfectly delicious without the nuts and liqueur. My primary modification was to use regular whole milk, making it accessible for most home bakers. However, Ivy Manning’s original recipe cleverly uses almond or soy milk, making it entirely vegan-friendly! This is a fantastic feature for those with dietary restrictions or anyone looking to enjoy a plant-based dessert. If you need a vegan cake, simply swap the regular milk for your preferred plant-based milk (almond or soy work wonderfully), use vegan butter for the frosting, and omit the sour cream entirely, as the plant-based milk and cocoa will provide enough richness and moisture. These small changes open up a world of possibilities, making this recipe incredibly versatile and accommodating.
Pro Tips for Instant Pot Cake Success
Achieving a perfect Instant Pot chocolate cake is easier than you think with a few key tips:
- Pan Preparation is Key: Don’t skimp on greasing and flouring your 6-inch round cake pan. This ensures your cake releases cleanly after cooking, preserving its beautiful shape.
- Water Level Matters: Always ensure you have the specified amount of water (1.5 cups) in the Instant Pot liner. This water creates the essential steam for pressure cooking and prevents your pot from overheating.
- Perfect Blend, Not Over-mix: When combining your wet and dry ingredients, stir just until blended. Over-mixing can develop the gluten in the flour, leading to a tougher, less tender cake. A rubber scraper or mixing spoon is perfect for this.
- The Right Pan Size: A 6-inch pan is ideal for most 6-quart Instant Pots, fitting comfortably on the trivet. Ensure there’s enough space around the pan for steam to circulate.
- Sealing the Deal: Always double-check that your Instant Pot lid is properly sealed and the steam release valve is in the “Sealing” position before starting. This is crucial for pressure to build.
- Pressure Release (QR for Cake): Once the cooking time is complete, a quick release (QR) of the pressure is generally recommended for cakes. This helps prevent the cake from overcooking and becoming dense. Be cautious of the hot steam!
- Doneness Test: While Instant Pot cakes look different from oven cakes, a good indicator of doneness is an internal temperature around 200°F (93°C). The top might look slightly glossy or wet, which is normal for a steamed cake.
- Cooling is Crucial: Allow the cake to cool completely in the pan on a wire rack before attempting to frost it. A warm cake will melt the frosting, creating a mess. Patience here pays off!
- Ingredient Temperature: For the frosting, ensure your butter is softened to room temperature. This helps it cream smoothly with the powdered sugar, preventing lumps and ensuring a silky texture.

Recipe
Six Inch Instant Pot Chocolate Cake
Cookie Madness
Pin Recipe
Ingredients
- ⅔ cup all-purpose flour (84 grams)
- ½ cup sugar (100 grams)
- ¼ cup unsweetened cocoa powder (20 grams)
- ½ teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup whole milk
- 2 slightly generous tablespoons vegetable oil
- 1 teaspoon vanilla extract
Frosting
- 2 tablespoons plus 2 teaspoons butter softened (35 grams)
- 1 cup powdered sugar (120 grams)
- ¼ cup natural unsweetened cocoa powder (20 grams)
- ½ tablespoons sour cream
- 2 tablespoons milk (or as needed)
- ½ teaspoon vanilla extract
- Pinch of salt if using unsalted butter
Instructions
-
Thoroughly grease and flour a 6-inch round cake pan, ensuring all surfaces are lightly coated to prevent sticking.
-
Place the trivet (or steamer rack) into the bottom of your Instant Pot inner pot and add 1 ½ cups of water. This water is essential for creating the steam needed to cook the cake.
-
In a large mixing bowl, whisk together the all-purpose flour, sugar, unsweetened cocoa powder, baking powder, baking soda, and salt until they are well combined and no lumps remain.
-
In a separate small bowl or a 2-cup Pyrex measuring cup, combine the milk, vegetable oil, and vanilla extract. Pour this liquid mixture into the dry flour mixture and stir gently with a rubber scraper or mixing spoon until just blended. Be careful not to overmix, as this can make the cake tough.
-
Carefully pour the cake batter into the prepared 6-inch pan. Gently place the cake pan on the trivet inside the Instant Pot. Secure the Instant Pot lid, ensuring the sealing ring is properly in place. Rotate the steam release valve to the “Sealing” position. Select the “Manual” (or “Pressure Cook”) setting and set the cooking time to 28 minutes on high pressure. Once cooking is complete, perform a quick release (QR) by carefully moving the steam release valve to the “Venting” position to release the pressure rapidly. Once the float valve drops, open the lid and cautiously remove the cake. The top of the cake may appear slightly glossy, which is normal for a steamed cake. You can check for doneness with an instant-read thermometer; it should read around or slightly over 200°F (93°C).
-
Allow the chocolate cake to cool completely in the pan on a wire rack before attempting to frost it. While the cake cools, prepare the chocolate frosting. In a medium mixing bowl, using an electric mixer, beat together the softened butter and powdered sugar until light and fluffy. Stir in the cocoa powder and sour cream until incorporated. Finally, beat in the milk and vanilla extract, continuing to beat until the frosting is smooth, creamy, and spreadable. Add more milk, one teaspoon at a time, if a thinner consistency is desired. If using unsalted butter, add a pinch of salt to taste to enhance the flavor. Once the cake is fully cooled, spread the rich chocolate frosting evenly over the top.
Serving Suggestions & Pairing Ideas
Once your Six-Inch Instant Pot Chocolate Cake is beautifully frosted, the serving possibilities are endless! This rich, moist chocolate cake is delicious all on its own, but you can elevate the experience with a few simple additions. A scoop of vanilla bean ice cream or a dollop of freshly whipped cream makes for a classic pairing, adding a delightful contrast in temperature and texture. For a fruity touch, fresh berries like raspberries or strawberries cut through the richness of the chocolate and add a pop of color and natural sweetness. A light dusting of cocoa powder or a few more colorful sprinkles can also enhance its visual appeal. For the ultimate indulgence, consider a drizzle of caramel sauce or a sprinkle of chopped toasted nuts (like the hazelnuts from the original inspiration!). Pair it with a warm cup of coffee, a glass of milk, or even a glass of red wine for a sophisticated dessert experience.
Troubleshooting Common Instant Pot Cake Issues
While baking in an Instant Pot is generally straightforward, a few common issues can arise. Here’s how to troubleshoot them:
- Cake is Undercooked/Gooey in the Middle: If your cake isn’t quite done, it’s often due to insufficient cooking time or an inaccurate pressure build-up. Ensure your Instant Pot is properly sealed and give it a few extra minutes (e.g., 3-5 minutes) under pressure, followed by a quick release. Remember to test with a thermometer for that 200°F mark.
- Cake is Too Dense: Overmixing the batter is a common culprit for dense cakes. Gently fold the wet and dry ingredients just until combined. Also, ensure your baking soda and baking powder are fresh and active.
- Cake Sticks to the Pan: This usually means the pan wasn’t adequately greased and floured. A thorough coating is essential. Using parchment paper on the bottom of the pan can also provide an extra layer of non-stick security.
- Top of the Cake is Wet/Glossy: This is perfectly normal for Instant Pot cakes due to the steam cooking. It does not mean the cake is undercooked. The interior should still be light and moist. If you prefer a drier top, you can briefly pop it under a broiler in an oven for a minute or two (watch it carefully!) after removing it from the Instant Pot, but it’s rarely necessary.
- Water Gets into the Cake: If your cake pan isn’t properly covered (e.g., with foil), condensation can drip into the batter. Always cover your pan tightly with aluminum foil to prevent this, creating a barrier against the steam.
