Easy Peasy Peanut Brittle

Ingredients

Mix 1/2 c. light corn syrup and 1 c. sugar in a microwave proof bowl or large glass measure. Microwave on high for 4 minutes.
Add 1 c. salted peanuts and microwave for an additional 3 minutes.
Add 1 tsp. vanilla extract and 1 tsp. baking soda (careful — it foams up!)
Pour onto a buttered, rimmed cookie sheet pan. Cool and break into pieces.

Tips and Substitutions

• Peanuts: You can roast your own peanuts first for a deeper flavor, or try mixed nuts for a different twist.

• Corn syrup: Light corn syrup works best to prevent crystallization, but you can experiment with honey or golden syrup, keeping in mind texture may vary.

• Sugar: Granulated white sugar is ideal. Brown sugar will give a softer, chewier result.

• Microwave caution: Watch your sugar mixture closely. It can bubble and foam quickly once baking soda is added, so stir carefully and avoid burns.

Serving Ideas

• Break into small pieces for a snack mix or dessert topping.

• Wrap in cellophane bags tied with ribbons for easy gifts.

• Pair with coffee, tea, or hot chocolate for a sweet treat during cold months.

• Crush it and sprinkle over ice cream for an extra crunchy surprise.

Storage and Freezing

• Store in an airtight container at room temperature for up to 2 weeks.

• Avoid storing in the fridge, as moisture can make it sticky.

• For longer storage, wrap individual pieces in parchment and freeze up to 2 months. Thaw at room temperature before serving.

FAQ

Q: Why did my peanut brittle turn out sticky?
A: This usually happens if it’s not cooked long enough or stored in a humid environment. Make sure the sugar mixture bubbles properly before adding baking soda, and keep it in an airtight container.

Q: Can I use unsalted peanuts?
A: Yes! Just add a pinch of salt to balance the sweetness.

Q: What does the baking soda do?
A: It creates tiny bubbles in the sugar mixture, giving the brittle a lighter, crisp texture instead of being too dense.

Q: Can I make this on the stovetop instead of the microwave?
A: Definitely. Combine corn syrup, sugar, and peanuts in a saucepan and cook over medium heat until it reaches a golden caramel color. Then stir in vanilla and baking soda before pouring onto the pan.
