Almond brittle made in the microwave is a quick and easy thing to make that is so impressive! It’s a great housewarming present, and it’s great to perch a shard on top of champagne cupcakes, which I did last New Year’s Eve and thought it was cute! Decorating cupcakes with a crunchy brittle is something I do when I make my small batch chocolate cupcakes, too.

My Mom made microwave brittle with salted peanuts when I was growing up. The baking process is dangerous, though, so I wasn’t allowed to help.  I would watch from a safe distance while the sugar turned from clear to golden.  I loved the part when she stirred in the baking soda and the brittle foamed up.  So, just because this recipe is easy and consists of dumping 3 ingredients into a bowl and placing it in the microwave does not mean that your kids can help you.  We’re dealing with sugar that is almost 300 degrees.  You should also resist the urge to lick the spoon.  It looks like hard candy, but it’s actually hot lava when it comes out of the microwave.

Tips for making almond brittle in the microwave:

  • Please watch your brittle in the microwave while it cooks, especially after you add the almonds. Don’t be afraid to stop the microwave before the 2 minute mark. However, if your sugar turns dark brown or black, it’s ruined. That said, don’t be afraid for the sugar to turn a rich amber color.  Sugar must reach a certain temperature before it will set into the proper hardness of brittle.  At most, you might need to shave 15 seconds off your cooking time.  Any more than that and your brittle won’t set up.   Use a very deep bowl because boil-overs are disasterous.  Also, use raw almonds, or your nuts will taste burnt in the final product.
  • You might fear that your bowl is ruined after you’ve made the brittle.  To clean your bowl, simply fill it up with warm water, let it set for an hour and the excess candy will dissolve. No scrubbing required!

  • Light Corn Syrup. When I say light, it means clear, not low calorie. The grocery store has light and dark corn syrup. We need light here.
  • Granulated Sugar.
  • Almonds. Unsalted whole, raw almonds are the only thing to use. If the almonds are chopped or sliced (like the ones in my almond bars), it changes the cook time. Please follow the recipe as-stated. If you need a recipe for almond brittle with sliced almonds, please use google and find one.
  • Salt.
  • Butter.
  • Vanilla Extract.
  • Baking Soda: Baking soda is what makes brittle crunchy and, well, brittle. The baking soda reacts with the sugar to create carbon dioxide bubbles, which causes it to foam in the bowl. But this foam is what gives the brittle it’s delightfully light and crisp texture.

How to make microwave almond brittle:

  1. First, have ready all of the ingredients (corn syrup, sugar, almonds, salt, butter, vanilla, and baking soda), plus a small baking sheet for pouring the hot brittle on when it’s done cooking the microwave. I like to line a cookie sheet with one of these silicone mats because it’s truly nonstick.

  2. Next, use a large shallow bowl for making this recipe, because the recipe bubbles up several times, and you don’t want it to overflow. Add the corn syrup and sugar to the bowl, stir to combine.

  3. Microwave for 3 minutes on HIGH. It should be bubbling and boiling quite a lot. See photo.
