Notes on ingredients

You can find a complete list of ingredients with exact amounts and instructions in the recipe card below.
  • Sweet potato puree: Bake sweet potatoes and puree them in advance. See How to make sweet potato puree for details.
  • Almond butter: Adds creaminess and a mild nutty flavor. Substitute with peanut butter, cashew butter or another drippy nut butter if preferred.
  • Oat flour: Naturally gluten-free. If you have celiac disease or gluten sensitivity, use certified gluten-free oat flour to avoid cross-contamination.
  • Almond flour: Made from blanched almonds; finer in texture than almond meal and adds a delicate nutty note.
  • Date sugar: A minimally processed alternative to refined sugar made from ground dried dates; it contributes rich, caramel-like sweetness.
  • Gingerbread spice mix: Can be swapped for pumpkin pie spice if needed.
  • Lemon zest: Fresh lemon zest brightens the flavor and balances the sweetness.
  • Rice milk: Use cashew, soy, oat or almond milk as alternatives. If you are not vegan, regular dairy milk will work as well.

Sweet potatoes: delicious and nutritious

Why I love sweet potatoes:

  • They are affordable and available year-round.
  • A great addition to a healthy diet with multiple benefits.
  • An excellent source of beta carotene, vitamin C, potassium and fiber.
  • Nutritious, filling, and naturally sweet.
  • Versatile — they work well in both sweet and savory dishes.
  • Can be boiled, baked, steamed or roasted.
