Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 cup roasted peanuts (unsalted, skins removed)
3/4 cup sugar (150 g)
2 tbsp water
1 tbsp butter
1/4 tsp baking soda
1/2 tsp vanilla extract (optional)
pinch of salt
Directions
Start by preparing a baking sheet lined with parchment paper or a lightly greased surface. Set it aside so it’s ready when the brittle is cooked.
In a medium saucepan, combine the sugar and water. Place the pan over medium heat and stir gently until the sugar dissolves completely. Once dissolved, stop stirring and allow the mixture to cook undisturbed. It will begin to bubble and gradually turn into a golden caramel.
When the mixture reaches a rich amber color, quickly add the roasted peanuts and stir to coat them evenly. Immediately add the butter and mix until melted and fully incorporated.
Remove the saucepan from heat and quickly stir in the baking soda, vanilla extract (if using), and a pinch of salt. The mixture will foam slightly—this is normal and helps create the light, airy texture of the brittle.
Pour the mixture onto the prepared baking sheet. Use a spatula to spread it into a thin, even layer. Work quickly, as the mixture hardens fast.
Allow the brittle to cool completely at room temperature. Once hardened, break it into pieces of your desired size.

Variations
You can easily customize peanut brittle to suit your taste. Swap peanuts with almonds, cashews, or a mix of nuts for a different flavor profile. Add a sprinkle of sesame seeds for extra crunch and a subtle nutty aroma.
For a richer taste, try adding a small pinch of cinnamon or a drop of almond extract instead of vanilla. If you enjoy a slightly salty contrast, sprinkle a bit of flaky salt over the brittle right after spreading it.
Chocolate lovers can drizzle melted chocolate over the cooled brittle or dip pieces halfway for a decorative and indulgent twist.
Storage/Reheating
Store peanut brittle in an airtight container at room temperature. It will stay fresh and crunchy for up to two weeks if kept in a cool, dry place. Avoid humidity, as moisture can make the brittle sticky.
Do not refrigerate, as condensation can affect the texture. If the brittle becomes slightly soft, you can place it in a low-temperature oven (around 120°C) for a few minutes to help restore some crispness, then let it cool again.
FAQs
How do I know when the sugar is ready?
The sugar should reach a deep amber color. Be careful not to let it turn too dark, as it can taste burnt.
Why is baking soda added?
Baking soda creates tiny air bubbles, giving the brittle a lighter and crunchier texture.
Can I use salted peanuts?
Yes, but reduce or omit the added pinch of salt to avoid an overly salty result.
What if my brittle turns out too hard?
Peanut brittle is naturally hard, but spreading it thinner can make it easier to bite.
Can I make this without butter?
Yes, but butter adds richness and helps improve the texture.
Why did my brittle become sticky?
Humidity is usually the cause. Store it in a dry, airtight container to prevent this.
Can I double the recipe?
Yes, but work quickly when mixing and spreading, as the caramel hardens fast.
Is a candy thermometer required?
No, you can rely on the color of the caramel, but a thermometer can help for precision.
Can I add spices?
Absolutely. Cinnamon or a hint of nutmeg can enhance the flavor.
How long does it last?
When stored properly, peanut brittle can last up to two weeks.
