Browning the Butter
Browning butter is a simple technique that adds a rich, nutty flavor to baked goods, sauces, and more. I chose to use browned butter in the recipe because the nutty flavor pairs perfectly with the oats and peanut butter! Follow these steps to get perfectly browned butter every time:
- Melt the butter in the saucepan over medium heat. Stir occasionally as it melts completely.
- Once melted, the butter will begin to bubble and foam. Keep stirring to prevent burning and to ensure even browning.
- After a few minutes, the butter will turn a golden color, and you’ll notice a nutty aroma. Brown specks (toasted milk solids) will form at the bottom of the pan—this is when you know it’s ready.
- Once the butter reaches a deep golden brown, remove it from the heat to prevent burning. The butter will continue to cook slightly from residual heat.
- Pour the browned butter (including the flavorful brown bits) into a heatproof bowl. Let it cool slightly before using in your recipe.
Bonus Tips:
- If your butter turns black instead of brown, it has burned—start over with fresh butter.
- For extra flavor, add a pinch of salt to enhance the nuttiness.
- Browned butter can be stored in an airtight container in the fridge for later use!
