Peanut Brittle, and where to source it

Brittle is a hard-crack candy, so cook the syrup to 300F exactly or it stays chewy instead of snapping. Baking soda stirred in at the end foams the caramel so it spreads thin and light rather than dense and tooth-cracking.

Straight Answers
Can you make Peanut Brittle in an air fryer? — Yes

Yes — this is exactly what an air fryer does well. Work in a single layer so the air can move, and shake or flip halfway for even crisping. It runs a touch faster than the oven, so check early.

Can you freeze Peanut Brittle? — Yes

Yes — freeze it well-wrapped, then reheat or toast straight from frozen. Frost or glaze after thawing.

Can you make Peanut Brittle ahead of time? — Prep ahead

Best fried to order — the crunch fades if it sits. Do the breading or shaping ahead and cook it fresh when you serve.

Is Peanut Brittle gluten-free? — Yes

Yes — nothing in this recipe as written contains gluten. As always, glance at the labels on any packaged items (broth, sauces, chocolate), since brands vary.

Is Peanut Brittle vegan? — Vegetarian, not vegan

It’s vegetarian but not vegan as written — it has dairy. Make it vegan: use plant milk, oil, or a vegan cheese for the dairy.
