Spread the almonds on a rimmed cookie sheet, preferably with a baking mat or sheet of parchment underneath them. Drizzle the maple syrup over the almonds and toss the nuts with your fingers so that they get evenly coated. Roast them at 325 degrees for 20 minutes, tossing at least once during the cooking process.

When the nuts are fully roasted, remove the pan from the oven and let cool for at least 10-15 minutes.

Pour the nuts into the food processor and pulse to begin breaking them up. Add a drizzle of your oil and run the processor 30-45 seconds. Remove the lid and scrape down the sides. Continue with this process/scrape/drizzle procedure until your nuts have broken down in butter. You may not need all the oil, it just depends on the moisture content of the almonds.

Store your homemade almond butter in the fridge, as with many things you make at home, it will not have quite the lifespan that similar store bought products have.
