Step 1To make the dulche de leche, you'll need a batch of our Keto Condensed Milk. Place the butter, 2 cups cream, almond milk and Allulose into a saucepan. Bring to a boil over a medium-high heat. Once it starts simmering, turn the heat down to low. Reduce to about half of the volume. This will take 30 to 45 minutes. When done, remove from the heat and blend using an immersion blender until smooth and creamy (this will help remove any clumps).
