FAQ

Can I use quick oats instead?

No, quick oats will become mushy in the slow cooker. Steel cut oats hold their texture during long cooking.

What if I don't have vanilla bean?

Substitute 1 teaspoon vanilla extract added in the last 30 minutes of cooking to prevent alcohol from cooking off completely.

How long will leftovers keep?

Refrigerate up to 5 days. Reheat individual portions with a splash of milk until warmed through and creamy again.
