From the handwritten recipe

Bulletproof Coffee

Ingredients

  • 1 cup freshly brewed coffee
  • 1–2 Tbsp unrefined coconut oil
  • 1–2 Tbsp unsalted butter

Directions

  1. Brew 1 cup of coffee.
  2. Add the hot coffee to a heat-safe container suitable for blending. Add 1–2 tablespoons unrefined coconut oil and 1–2 tablespoons unsalted butter.
  3. If desired, choose flavor additions from the list below. Start with a small pinch of spices or a little cacao and adjust to taste; the original card gives no quantities for these additions.
  4. Blend with an immersion blender until the fats are incorporated and the coffee is creamy and lightly frothy, about 15–30 seconds. Keep the blender head submerged to prevent splashing. Alternatively, use a countertop blender rated for hot liquids, following its venting and fill instructions.
  5. Pour into a mug and serve warm. Stir again if the fats separate as the coffee cools.

Original card notes

“No Sweetener” and “No Cream.” The handwritten recipe lists flavor choices without amounts. For safety, do not shake hot coffee in a sealed jar or blend boiling liquid in a sealed blender.
