Add the almonds to a pan lined with parchment paper. Roast for 12-15 minutes until them start to smell really fragrant. Be careful to watch them so they don't burn.
Add the almonds to a food processor and process for about 5-10 minutes, scraping the sides as needed during the process. You will have to do this a few times in the beginning. It will seem like it is just going to stay a flour, but trust me, after a few minutes it will start to come together. Have patience. Once it starts to turn into butter, let it go until it becomes super duper creamy. Don't stop too soon or it won't become silky smooth. Don't stop when it's still overly thick and chunky. Once it is easily pouring off of a spoon, then it is done. The roasted almonds give a wonderful sweetness. Yum.
