Baking a cake in an Instant Pot transforms dessert-making into a foolproof, mess-free process that delivers fluffy layers without a single ounce of oil. The secret lies in leveraging steam pressure to create tender crumb and even rise—something traditional ovens can’t always match.
After years of testing, I’ve perfected this method to eliminate greasy results while keeping the texture impossibly light.
This recipe relies on a simple batter that uses applesauce as the fat substitute, delivering moisture without heaviness. The Instant Pot’s even heat distribution ensures consistent baking, and the natural release method prevents overcooking.
What you’ll end up with is a cake that’s moist, tender, and perfectly golden—ideal for birthdays, celebrations, or satisfying cravings.
The beauty of Instant Pot cakes is their versatility—you can adapt flavors from vanilla to chocolate to spice cakes with equal success. No special equipment beyond your Instant Pot and mixing bowls is needed, making this the simplest path to homemade cake that even beginners can master.
Let’s get started with this game-changing technique.
Once baked, the cake develops a delicate crumb that stays fresh for days, making it perfect for meal prep or gifting. Whether you’re new to pressure cooking or a seasoned pro, this method delivers restaurant-quality results with minimal effort. The only challenge? Resisting seconds.
Ingredients for instant pot cake
Twelve simple ingredients transform into a light, golden cake with perfect layers—no oil needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ½ cup | Softened for optimal mixing |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown preferred |
| Unsweetened Applesauce 🍎 | ½ cup | Unseasoned, unsweetened variety |
| Large Eggs 🥚 | 2 whole | Room temperature for best results |
| Vanilla Extract 🍯 | 2 tsp | Pure, high-quality extract |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for light texture |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Cake Mix 🍰 | 15 ¼ oz | High-quality boxed mix |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Vegetable Oil 🫒 | ¼ cup | Light or canola oil |
| Baking Soda 🧂 | ½ tsp | Freshly measured |
The applesauce is the game-changer here, replacing butter while maintaining moisture. Opt for unsweetened, unseasoned varieties—those labeled ‘unsweetened’ at Trader Joe’s or Whole Foods work best. Diamond Crystal baking powder is preferred for reliable rise, though Arm & Hammer works in a pinch. The vanilla cake mix should be high-quality; brands like Betty Crocker or Pillsbury deliver consistent results. For the flour, Bob’s Red Mill all-purpose is ideal, but sift it yourself to avoid lumps. The unsalted butter should be softened to room temperature—press your finger into it and it should leave a slight indent.
Short on applesauce? Pumpkin puree or mashed banana work at the same quantity, though flavor will shift. No baking powder? Baking soda plus cream of tartar (half the amount of baking soda) substitutes effectively. The vanilla extract must be pure—Nielsen-Massey or Goya are reliable brands. For the milk, whole milk adds richness, but 2% or almond milk work in a bind. Vegetable oil can be swapped for melted coconut oil (same amount), though texture may vary slightly. Always measure your baking soda and baking powder fresh—old leaveners lose potency and can cause flat cakes.
Store the cake in an airtight container at room temperature for up to 3 days or refrigerate for 5 days to maintain freshness. For longer storage, wrap tightly in plastic and freeze for up to 3 months. To reheat, cover with a damp paper towel and microwave for 10-15 seconds. The cake freezes beautifully—portion and wrap individual slices for convenient single servings. For best results, let the cake cool completely before slicing to prevent crumbling.

Step-by-step instructions for Instant Pot cake
This method delivers perfectly moist layers with minimal effort using your Instant Pot.
Prepare the Wet Ingredients
In a medium bowl, combine the 0.5 cup unsalted butter and 1.5 cups granulated sugar. Using an electric mixer on medium speed, beat for 3-4 minutes until the mixture becomes light and fluffy. This step incorporates air, which is essential for the cake’s rise and tender crumb.
Next, add the 0.5 cup unsweetened applesauce, 2 whole large eggs, and 2 teaspoons vanilla extract. Mix on low speed until fully incorporated. The applesauce acts as a natural fat substitute, keeping the cake moist without adding oil. The eggs provide structure while maintaining a tender texture.
Combine Dry Ingredients
In a separate bowl, whisk together the 15.25 oz vanilla cake mix, 1.5 cups all-purpose flour, 2 teaspoons baking powder, 0.5 teaspoon salt, and 0.5 teaspoon baking soda. Sift the ingredients to ensure a light, airy texture. This prevents dense pockets in the cake and promotes even rising.
Gradually add the dry mixture to the wet ingredients, mixing on low speed just until combined. Avoid overmixing—this can lead to a tough cake. The batter should be thick but pourable, resembling traditional cake batter.
Prepare the Instant Pot
Lightly grease a 6-quart Instant Pot with 0.25 cup vegetable oil or line the bottom with parchment paper. Pour the batter evenly into the pot, spreading it into a 1-inch thick layer. The even distribution ensures consistent baking and prevents uneven layers.
Add the 0.5 cup milk to the Instant Pot’s steam release valve. This creates steam during cooking, which helps the cake rise and develop a tender crumb. Close the lid securely, ensuring the valve is set to “Sealing.”
Cook and Finish
Set the Instant Pot to High Pressure and cook for 20 minutes. Once the cooking cycle completes, allow a 10-minute natural release before carefully opening the lid. This gradual release prevents the cake from collapsing or becoming dense.
Remove the cake from the pot and let it cool in the pan for 15 minutes. Then, transfer it to a wire rack to cool completely. The cake should have a golden top with a tender, moist interior. If the cake pulls away from the edges slightly, it’s a good sign—this indicates proper baking.
Pro Tips For Making Instant Pot Cake
- Melt Butter First: Skip the cold butter shortcut—melt it first in the Instant Pot on high for 30 seconds before adding other ingredients. This ensures even mixing and prevents greasy pockets that happen when cold butter clumps. (Yes, even if you’re tempted to toss it in raw.)
- Whisk Eggs Until Smooth: Beat the eggs with the sugar until fully dissolved and slightly thickened—about 2 minutes with a whisk. I learned this the hard way: unmixed eggs create dense, gummy cake. No one wants a brick in their Instant Pot.
- Avoid Overmixing the Batter: Mix just until combined—lumpy is fine. Overworking the applesauce-butter mix introduces too much air, which collapses under pressure. Your cake will rise better if you treat the batter like it’s fragile.
- Let It Sit After Cooking: Open the lid and let the cake rest for 10 minutes before removing it. Rushing pulls the cake apart—it’s still setting inside. Patience here means cleaner slices and no crumbling edges. (Your future self will curse you if you skip this.)

Frequently asked questions
Why does this recipe use applesauce instead of butter?
The applesauce replaces butter while keeping the cake moist and light—no oil needed! It adds natural sweetness and prevents greasiness, making the texture tender without heaviness. Plus, it’s lower in fat than traditional butter-based cakes.
Can I make this cake in a regular oven instead?
Yes, but results may vary. Preheat to 350°F and bake in a greased 6-inch round pan for 30-35 minutes. The Instant Pot’s steam pressure creates even layers and moisture that ovens can’t always replicate. For best results, stick with the pressure method.
What if my cake comes out dense or gummy?
Overmixing the batter or opening the lid too soon are common culprits. Ensure a 10-minute natural release and avoid peeking during cooking. Also, check that your baking powder is fresh—old leaveners lose potency and cause flat cakes.
How do I frost this cake without it sinking in?
Let the cake cool completely before frosting. Use a stable base like cream cheese frosting or buttercream and apply a thin crumb coat first. Chill for 15 minutes before adding the final layer. For extra stability, layer with cake boards or parchment paper.
Can I make this cake gluten-free?
Swap the all-purpose flour for a 1:1 gluten-free baking flour blend (like Bob’s Red Mill) and add ½ teaspoon xanthan gum. Reduce milk to ¼ cup to compensate for moisture differences. Test with a small batch first to adjust texture.
