Ingredients
• ¾ cup / 84g almond flour
• ¾ cup / 90g coconut flour
• ¾ cup / 144g Swerve or other erythritol-based sweetener
• 2 tsp pumpkin pie spice mix
• 1 tsp baking soda
• ½ tsp baking powder
• ½ tsp salt
• ½ cup / 120g full-fat Greek yogurt
• ¼ cup / 60g pumpkin puree
• 2 tbsp / 30ml coconut oil, melted
• 1 large egg
• 1 tsp vanilla extract
Instructions
1. Directions
2. Prepare the Pan: Thoroughly grease a small bundt cake pan suitable for the Instant Pot. Set it aside.
3. Mix Dry : In a large mixing bowl, whisk together the almond flour, coconut flour, Swerve, pumpkin pie spice mix, baking soda, baking powder, and salt until well combined.
4. Add Wet : To the dry , add the melted coconut oil, Greek yogurt, pumpkin puree, egg, and vanilla extract.
5. Combine the Batter: Using a hand mixer or a stand mixer with a paddle attachment, beat the mixture on medium-high speed until the batter is smooth and fully incorporated.
6. Fill the Pan: Carefully transfer the batter into your prepared bundt pan, spreading it evenly. Tightly cover the top of the pan with a piece of aluminum foil.
7. Set Up the Instant Pot: Place the trivet inside the inner pot of your Instant Pot and pour in 2 cups of water. Carefully lower the foil-covered bundt pan onto the trivet.
8. Pressure Cook: Secure the Instant Pot lid and turn the steam release handle to the “Sealing” position. Select the “Manual” or “Pressure Cook” button and set the timer for 30 minutes on high pressure.
9. Release Pressure: Once the cooking cycle is complete, perform a quick pressure release by carefully turning the steam release handle to “Venting”.
10. Cool and Serve: Once the pin has dropped, open the lid. Using oven mitts, gently lift the pan out of the pot. Let it cool on a wire rack for at least 20-30 minutes before removing the foil. Chill completely before carefully inverting the cake onto a serving plate.

Pro Tips
• For an extra-clean release, grease the bundt pan thoroughly with coconut oil and then “flour” it with a light dusting of almond flour before adding the batter.
• Be careful not to overmix the batter once the wet and dry are combined. Mix just until smooth to ensure a tender, not dense, crumb.
• Patience is key! Allow the cake to cool significantly, or even chill in the refrigerator for 30 minutes, before attempting to invert it. This prevents the delicate cake from breaking.
• Elevate your cake with a simple keto-friendly glaze made from powdered sweetener, a splash of heavy cream, and a pinch of cinnamon.
FAQ
Q: Can I use a different keto sweetener
A: Yes, this recipe is flexible. You can use Swerve or another erythritol-based sweetener that measures 1:1 like sugar. Using a different type of keto sweetener may alter the final texture and sweetness.
Q: Why did my keto bundt cake fall apart
A: Keto cakes are delicate. To prevent breaking, ensure you grease the pan very well and, most importantly, let the cake cool completely in the pan for at least 20-30 minutes before attempting to invert it. Chilling it briefly can also help it firm up.
Q: Can I make this pumpkin cake in the oven instead of an Instant Pot
A: This recipe is specifically designed for the moist, high-pressure environment of an Instant Pot, which creates an incredibly tender crumb. Baking it in a conventional oven would require significant adjustments to the recipe and cooking time, and we cannot guarantee the same result.
Q: What size bundt pan should I use for my Instant Pot
A: You will need a small bundt pan that fits comfortably inside your Instant Pot on top of the trivet. Typically, a 6-cup or 7-inch bundt pan works well for most 6-quart or 8-quart Instant Pot models.
