1. Combine ingredients: In a small saucepan, whisk together coconut milk, sweetener, chia seeds, vanilla extract, and lemon juice. 2. Heat the mixture: Warm over low heat for 3-5 minutes, stirring constantly until the sweetener dissolves. Avoid overheating to prevent the coconut milk from separating. 3. Let it thicken: Remove from heat and allow the mixture to cool slightly. The chia seeds will naturally thicken as it sits. 4. Refrigerate: Transfer to a bowl or an airtight container and refrigerate for at least 4 hours (overnight for best results). 5. Serve: Stir well before serving. Add your favorite keto toppings, like nuts, berries, or unsweetened coconut flakes.
