1. In a mixing bowl, combine chia seeds, almond milk, heavy cream, vanilla extract, and erythritol. Mix well until all ingredients are well combined.

2. Cover the bowl with plastic wrap and refrigerate for at least 2 hours or overnight. The chia seeds will absorb the liquid and create a pudding-like consistency.

3. Once the chia pudding is set, give it a good stir to break up any clumps. If the pudding is too thick, add a splash of almond milk to thin it out.

4. Spoon the chia pudding into serving dishes and top with sliced almonds, shredded coconut, or berries if desired.

5. Serve chilled and enjoy your delicious keto chia pudding!
