I tried these with and without date sugar as a sweetener. If you prefer a sweeter cookie, go with the date sugar. If you prefer to keep the carbs as low as possible, go without! Either way, these Chocolate Hazelnut Cookies are full of flavor! Enjoy!

Prep Time 10 minutes mins

Servings 3

Ingredients

Cookie:

  • ⅓ cup (75 g) hazelnut butter (I make mine from hazelnut meal)
  • ¼ cup (60 g) water
  • ¼ cup (37 g) chocolate pea protein
  • 2 tablespoons (11 g) cocoa powder
  • a pinch of sea salt
  • ⅛ teaspoon ground cinnamon (optional)
  • 1 tablespoon (9 g) date sugar (optional)

Chocolate drizzle:

  • 3 tablespoons (21 g) chocolate whey protein
  • 1 tablespoon (9 g) date sugar (optional)
  • 1-2 tablespoons (15 g) water

Instructions
 

  • Preheat oven to 325F (163C).
  • Begin to make the cookie dough by mixing the hazelnut butter and water until smooth.
    ⅓ cup (75 g) hazelnut butter, ¼ cup (60 g) water
  • Mix in the remaining cookie ingredients, and mix well.
    ¼ cup (37 g) chocolate pea protein, 2 tablespoons (11 g) cocoa powder, a pinch of sea salt, ⅛ teaspoon ground cinnamon, 1 tablespoon (9 g) date sugar
  • Form into 9 pieces, and roll each into a ball. Place on a parchment-lined cookie sheet.
  • Flatten each cookie (with your hand or the back of a large spoon).
  • Bake for 10-12 minutes, until firm.
  • Remove from oven and let cool.
  • Mix the icing ingredients until smooth (start with 1 tablespoon of water and add by the teaspoon). Drizzle over cooled cookies.
    3 tablespoons (21 g) chocolate whey protein , 1 tablespoon (9 g) date sugar, 1-2 tablespoons (15 g) water
  • Enjoy! Store in the refrigerator.

Notes

A note about substitutions: because each type of protein powder has a distinct flavor and texture when baked, I would not try substituting different types of protein powders in this recipe. (Use a rice/pea blend for the cookie and whey for the icing. See my Recipe Basics video for examples of what goes wrong when you use the wrong protein powder.) For a vegan chocolate drizzle, I suggest melted Raw Chocolate over chilled cookies.
I make my hazelnut butter by putting hazelnut meal in the food processor.
