Add the almonds and pecans to your food processor or high speed blender. Process until smooth and creamy like peanut butter. This may take about 5 minutes depending on your machine.
Add the vanilla, cinnamon and salt, and pulse to combine ingredients. Store almond butter in a glass jar or airtight container.
*In place of ground vanilla bean powder you can use the seeds of a vanilla bean or vanilla extract. Note that vanilla extract will give you a milder vanilla taste.**In place of the pecans, you can use more almonds. I think the pecans add even more flavor to this recipe. If pecans are not your favorite, try this recipe with macadamia nuts, hazelnuts, or another nut of your preference.
