Preheat the oven to 350F. 

Place almonds on a large baking tray and place in the oven for 10-12 minutes, until fragrant and toasted.

Remove from the oven and let cool completely.

Once cool, place toasted almonds in a high-speed blender or food processor. Pulse until a crumbly texture remains. Stir using a rubber spatula. If desired, add salt. Continue pulsing until smooth and creamy, regularly scraping down the sides.
NOTE: 4 cups are needed if using a blender or large food processor. Hand-held blender works well for small amounts.

Transfer the homemade almond butter into a jar or container.
