Making homemade almond butter is easier than you might expect! It tastes so much better than the store-bought version, you may never go back once you taste it.
Preheat the oven to 350ºF and spread the almonds out in a single layer on a large, rimmed baking sheet. Place them in the oven to roast for 10 minutes, then remove the pan and let them cool for at least 10 minutes before moving on. (Placing very hot almonds in your machine could melt it, so be patient!)
Transfer the cooled almonds (it's okay if they are slightly warm) to a large food processor fitted with an "S" blade. Secure the lid and start processing. The almonds will start to look like flour and stick to the sides of your machine, but after 4 to 5 minutes of processing, it will change into a thicker consistency and release from the sides of the machine.
You can stop and scrape the sides of your food processor at this point if you'd like to, but the whole process can be relatively hands-off with almost no scraping required. In fact, you can let the machine run for 8 to 10 minutes without scraping, and the nut butter will form on its own! This is the advantage of using a food processor, rather than a blender. (See tips in this post if you prefer to use a blender, though.)
Once the almonds have been processed for 8 to 10 minutes, they should reach a runny, drippy consistency. At this point, you can add in a 1/2 teaspoon of fine sea salt or ground cinnamon, if you'd like added flavor. Do NOT add any wet ingredients, or it could affect the final texture.
Store homemade almond butter in a 16-ounce mason jar. It will need to cool completely before you add the lid, so it won't collect steam inside the jar. Adding moisture to the jar could affect the shelf life. Almond butter can be stored in an airtight container in the fridge for at least 1 month when no moisture is introduced, so always be sure to use a clean spoon or knife when using it.

Notes
Nutrition information is for 1 ounce of almond butter or roughly 2 tablespoons. This information is automatically calculated and is just an estimate, not a guarantee.I used this 12-cup food processor (affiliate link) when testing this method. Other brands and sizes may vary.If you need to use a high-speed blender, be sure to read the full post for tips! You'll need a different quantity of almonds and a tamper will need to be used often, in that case.
