- Preheat the oven to 350°F. Spread the walnuts and pecans on a lined baking sheet and bake in the heated for about 8-10 minutes, or until fragrant and lightly toasted. Let cool for a few minutes on the counter top. You can also leave the nuts raw, if you prefer.
- When the nuts are cool, set aside 1/4 cup toasted walnuts to pulse in at the end. Add the rest of the nuts to your food processor or high-powered blender (I used my Vitamix). Process for about 3-6 minutes, scraping down as necessary. Your time might be shorter if you’re using a high-powered blender – it will take a little bit longer in the food processor and require more scraping down.
- When the walnuts and pecans have broken down into a smooth, creamy butter, add the freeze-dried bananas, cinnamon, vanilla bean powder, and salt. Process to incorporate, and taste. Adjust add-ins as desired. Finally, add the cacao nibs and toasted walnuts and pulse a few times to incorporate and break up the walnuts a bit.
- Transfer to a glass jar or two (like a mason or Weck jar) and store in the refrigerator for 2-3 months.
