Oat Brittle Ingredients

  • For the Brittle
  • Oats – Old-fashioned oats provide the perfect chewy texture for your brittle.
  • Sugar – This adds essential sweetness and contributes to that lovely caramelized flavor.
  • Brown Sugar – Not only does it deepen the syrupy flavor, but it also keeps the oat brittle moist; you can substitute it with coconut sugar for a unique taste.
  • Water – This ingredient helps dissolve the sugars and creates a syrup-like consistency—no substitute needed here!
  • Golden Syrup – Key for obtaining the signature chewy texture; if unavailable, light corn syrup or honey works nicely.
  • Butter – Lending a rich flavor and aiding in the formation of the brittle texture, you may use vegan butter for a dairy-free version.
  • Baking Soda – This reacts to lighten the mixture, ensuring a delicate crisp finish—an essential include!

Step‑by‑Step Instructions for Oat Brittle

Step 1: Preheat and Toast Oats
Begin by preheating your oven to 350°F (175°C) if you prefer to toast your oats for enhanced flavor. Spread the old-fashioned oats evenly on a baking sheet, then toast them in the oven for about 10-15 minutes, stirring occasionally until they turn lightly golden and fragrant. Keep a close eye on them to prevent burning, and set aside to cool once done.

Step 2: Prepare Sugar Mixture
In a heavy-bottomed saucepan, combine the granulated sugar, brown sugar, Golden Syrup, and water over low heat. Stir the mixture gently until the sugars dissolve completely, usually in about 5 minutes. This creates a syrup consistency that will form the base of your oat brittle. As it melts, watch for a smooth, glossy appearance indicating readiness for the next step.

Step 3: Add Butter and Boil
Once the sugar mixture is fully dissolved, add the butter and increase the heat to medium-high. Allow the mixture to come to a rolling boil without stirring; this should take about 5-7 minutes. Keep a close eye on it and look for a beautiful golden color developing. This step is crucial for achieving the caramelized flavor in your oat brittle.

Step 4: Monitor Temperature
Using a candy thermometer, continue boiling the mixture until it reaches 310°F (154°C). At this temperature, the sugar forms brittle threads when tested in cold water. This should take about 5 minutes, depending on your stove’s heat. Stay attentive during this process to avoid burning, as it can go quickly from perfect to too dark.

Step 5: Fold in Baking Soda and Oats
Once the mixture reaches the desired temperature, remove it from the heat and quickly stir in the baking soda. This will create a bubbly reaction that lightens the mixture. Immediately fold in your toasted oats, mixing well until they are fully coated. Aim for an even distribution of oats to achieve a consistent texture in your oat brittle.

Step 6: Spread Mixture
Prepare a buttered or silicone-lined cookie sheet for pouring the oat mixture. With a spatula, carefully transfer the oat brittle mixture onto the sheet, spreading it evenly into a thin layer. This should be done quickly to maintain the mixture’s warmth and ensure it spreads well. Aim for a thickness of about 1/4 inch for the best results.

Step 7: Cool and Break
Allow the oat brittle to cool completely at room temperature, which may take about 30-45 minutes. Once cooled and hardened, break it into desired pieces for snacking or gifting. Store your delicious oat brittle in an airtight container to keep it fresh, and enjoy sharing this nut-free delight with others!

How to Store and Freeze Oat Brittle

Airtight Container: Store your oat brittle in an airtight container at room temperature for up to 2 weeks to keep its crunchiness intact.

Fridge: If you prefer a crisper texture, refrigerate the brittle, but remember it may lose some crunch and last for about 3 weeks.

Freezer: For long-term storage, wrap the brittle tightly in plastic wrap and place it in a freezer-safe bag. It can be frozen for up to 3 months; just thaw at room temperature before enjoying.

Reheating: If the brittle softens, you can re-crisp it in a preheated oven at 300°F (150°C) for about 5 minutes, allowing that delightful crunch to return.

Expert Tips for Oat Brittle

  • Use a Candy Thermometer: Precision is key in achieving that perfect brittle consistency, so don’t skip this essential tool.
  • Avoid Stirring After Butter: Once the butter is added to the sugar mixture, refrain from stirring. This maintains the necessary structure of the oat brittle.
  • Cool Completely: Patience is crucial! Allow the brittle to cool all the way to ensure it hardens properly and achieves that satisfying crunch.
  • Toast Oats for Flavor: Toasting your oats enhances their flavor, giving your oat brittle a deeper, nutty taste that everyone will enjoy.
  • Experiment with Flavors: Feel free to get creative! Add vanilla or almond extract for an aromatic twist to your oat brittle.
