Goat's milk caramel atole is a decadent, warm Mexican breakfast treat. This family-friendly, vegetarian drink is a rich, sweet, traditional beverage for special morning occasions.
In a medium saucepan, combine whole milk and the cinnamon stick. Warm gently over medium-low heat, stirring frequently, until the milk is steaming but not boiling (about 5 minutes).
In a small bowl, whisk masa harina with 1/2 cup of warm milk from the pan until smooth and lump-free. This ensures even thickening later.
Return the masa mixture to the saucepan. Increase heat to medium. Stir constantly for 2–3 minutes to avoid clumping and ensure smooth texture.
Add cajeta, vanilla extract, and salt to the saucepan. Continue to cook, whisking frequently, until the mixture is thickened and coats the back of a spoon (about 8–10 minutes). Watch closely to prevent scorching.
Remove from heat, discard the cinnamon stick, and serve immediately in mugs while hot and velvety. Stir before serving as the atole thickens as it sits.
