Equipment
- Oven or airfryer
- Baking tray
- Immersion blender or blender
Ingredients
For the flax eggs:
- 2 tablespoons flaxseed meal
- 5 tablespoons warm water
Dry Ingredients:
- 2 cups rolled oats
- 1 cup unsweetened protein powder or almond flour or almond meal (see notes)
- 2 teaspoons cinnamon
- 1 teaspoon baking soda
Wet Ingredients:
- 9 Medjool dates pitted (or ¾ cup date paste)
- ⅔ cup hot water
- ½ cup tahini or unsweetened runny nut butter
- 1 ½ teaspoons vanilla extract
- 2 teaspoons lemon juice
- 2 tablespoons unsweetened nondairy milk or water, plus more as needed (see notes)
Optional ingredients:
- ⅓ cup hemp hearts
- ½ cup raw pumpkin seeds
- 2 tablespoons black sesame seeds
- ¾ cup unsweetened dried cranberries or dried barberries
Instructions
- Prepare flax eggs: Mix flaxseed meal and water. Refrigerate for at least 10 minutes.
- Make date paste: Add pitted dates to a heatproof jar with hot water. Let sit for 2 minutes, then blend until smooth with an immersion blender. Use store-bought paste if preferred.
- Preheat oven to 360ºF (182ºC). Line a baking sheet with parchment paper or use a nonstick sheet.
- Mix dry ingredients: In a large bowl, stir together oats, protein powder, cinnamon, and baking soda.
- Mix wet ingredients: In a separate bowl, combine flax eggs, date paste, tahini, lemon juice, and vanilla.
- Combine: Stir wet into dry until just combined. Add nondairy milk only as needed. The batter should be slightly moist and easy to scoop.
- Shape and bake: Use about ¾ cup batter per cookie. Shape into thick rounds and place on the baking sheet. Flatten them slightly and bake for 20–25 minutes on the middle rack until firm and lightly golden, flipping them over after 12 minutes.
- Cool completely before storing.
Notes
A complete meal - These cookies are intentionally calorie-dense and designed for a full breakfast or a satisfying pre-workout snack. For a lighter option, divide the dough into 12 smaller cookies and reduce the baking time slightly (start checking at 14–16 minutes).
Batter consistency: The batter should be thick, slightly moist, and easy to shape. Protein powders vary in how much liquid they absorb, so only add nondairy milk if needed. If the batter seems too wet, let it sit for 5 to 10 minutes so the oats and flax can absorb more moisture. Shape the cookies into thick, slightly flattened rounds rather than tall mounds so the centers bake through evenly.
I use this one-ingredient protein powder, but any variety will work. Otherwise, use almond flour or almond meal.
Other add-ins: chocolate chips, chopped nuts, chopped strawberries or apples, raisins, prunes, lemon zest, figs, turmeric, or poppy seeds.
