Ingredients

• 1 cup / 112g almond flour
• ½ cup / 60g fresh raspberries
• 1 tbsp / 15g unsweetened dark chocolate chips
• 3 large eggs
• 1 tbsp / 12g Swerve or other erythritol-based sweetener
• ¼ tsp / 1.25ml sugar-free vanilla extract
• ¼ tsp / 1.5g salt

Instructions

1. In a large mixing bowl, whisk together the almond flour, Swerve, and salt.
2. Add the eggs and vanilla extract to the dry , mixing until just combined. Gently fold in the fresh raspberries and dark chocolate chips.
3. Grease three small mason jars with cooking spray. Evenly distribute the cake batter among the jars.
4. Cover the top of each jar securely with a small piece of aluminum foil to prevent condensation from getting in.
5. Pour 2 cups of water into the inner pot of your Instant Pot and place the trivet inside.
6. Carefully arrange the foil-covered jars on the trivet.
7. Lock the Instant Pot lid, ensure the steam release handle is set to the “Sealing” position, and press the “Manual” or “Pressure Cook” button. Set the timer for 10 minutes on high pressure.
8. Once the cooking cycle is complete, perform a quick release by carefully turning the steam release handle to the “Venting” position.
9. Using oven mitts, remove the hot jars from the pot. Let them cool to room temperature before removing the foil and serving. Enjoy!

Pro Tips

• & Variations
• For a fudgier texture, slightly under-mix the batter. Over-mixing can make almond flour cakes tough.
• No fresh raspberries? Frozen ones work perfectly. Add them directly to the batter without thawing to prevent excess moisture.
• Ensure the foil covers are tight. This is crucial to prevent water from the Instant Pot from making the tops of your cakes soggy.
• Feel free to swap the berries! Blueberries or chopped strawberries are excellent low-carb alternatives.
• Serve warm with a dollop of keto-friendly whipped cream or a scoop of low-carb vanilla ice cream for an extra decadent treat.
