Ingredients You’ll Need to Make These Peanut Butter Oatmeal Chocolate Chip Cookies
To make these delightful cookies, assemble the following ingredients:
2 flax eggs (2 tablespoons ground flaxseed whisked with 6 tablespoons warm water, rested for 15 minutes)
¼ cup chopped walnuts (substitutable with your favorite nuts or mix-ins)
¼ cup organic coconut sugar (provides a soft sweetness)
½ teaspoon pure vanilla extract (for that soothing warmth)
¼ teaspoon aluminum-free baking powder (gives just enough lift)
1 tablespoon cacao powder (enhances the chocolate experience)
¼ cup finely milled gluten-free oat flour (for moisture)
½ cup dairy-free chocolate chips (because chocolate is a must)
2 tablespoons vegan chocolate chips (optional, for extra chocolatey goodness)
¼ teaspoon baking soda (aiding in that perfect rise)
½ teaspoon ground Ceylon cinnamon (adds a cozy spice)
1/8 teaspoon sea salt (to balance the sweetness)
2 tablespoons unrefined melted coconut oil (for richness)
¾ cup gluten-free rolled oats (the hearty base)
1 tablespoon maple syrup (to enhance sweetness and moisture)
¼ cup + 2 tablespoons natural creamy peanut butter, unsalted (the star of the show)
Sprinkle of flaky sea salt (optional, to enhance flavors)

How to Make These Cookies
Step 1: Prepare Your Flax Eggs
Start by making your flax eggs; whisk together the ground flaxseed and warm water in a small bowl. Allow it to sit for at least 15 minutes. This mixture creates a gel-like consistency that acts as a binder, similar to eggs.
Step 2: Mix the Wet Ingredients
In a large bowl, combine the flax egg, peanut butter, coconut sugar, maple syrup, vanilla extract, and melted coconut oil. Stir well until everything is smooth and well blended.
Step 3: Combine the Dry Ingredients
In another bowl, mix the rolled oats, gluten-free oat flour, cacao powder, baking powder, baking soda, cinnamon, and sea salt. Gently whisk to combine.
Step 4: Combine Wet and Dry Ingredients
Gradually add the dry mixture into the wet mixture. Stir until it’s fully combined. This is where you can fold in your chocolate chips and nuts. Be creative here!
Step 5: Shape the Cookies
Preheat your oven to 350°F (180°C) and line a baking sheet with parchment paper. Use a scoop or spoon to drop a heaping tablespoon of dough onto the baking sheet, leaving space for them to spread a bit.
Step 6: Bake
Place the baking sheet in the oven and bake for about 10-12 minutes, or until the edges are slightly golden. The centers may feel soft but they will firm up as they cool.
Step 7: Cool and Enjoy
Once baked, let the cookies cool on the baking sheet for a few minutes and then transfer them to a wire rack to cool completely. Enjoy them warm for that irresistible melt-in-your-mouth experience.
Tips for Success
Use Natural Peanut Butter – Choose a brand that contains only peanuts and salt. Avoid sugary spreads to keep these cookies healthy.
Experiment with Mix-Ins – Dried fruit, nuts, or seeds can add a unique flavor and boost the nutritional profile.
Don’t Over-Bake – Keep an eye on your cookies in the oven. They’ll continue to bake on the sheet, so make sure to take them out when they look slightly underbaked.
Let Them Cool Completely – These cookies get firmer once they’ve cooled, which is crucial for texture.
Store in an Airtight Container – To maintain their chewiness, store cookies in a sealed container.

Recommended Side Dishes for Peanut Butter Oatmeal Chocolate Chip Cookies
Fresh Fruit Salad
A colorful fruit salad can add a refreshing contrast to the rich flavors of the cookies. Mix seasonal fruits like strawberries, blueberries, and oranges.
Greek Yogurt Parfait
Layer Greek yogurt with granola and fresh fruit. The creamy yogurt balances the sweetness of the cookies, making a delightful pairing.
Milkshake
Whip up a homemade milkshake. Combine your favorite dairy or dairy-free ice cream with almond milk for a rich and nostalgic treat.
Mashed Avocado on Toast
Toast some bread and top it with mashed avocado and a sprinkle of salt. The creaminess offsets the cookies’ heaviness and is a great way to include healthy fats.
Substitute Options for Ingredients
Flax Eggs
If you’re in a hurry or run out of flaxseed, you can substitute with chia seeds in the same ratio.
Coconut Sugar
Brown sugar or maple sugar can be used if you don’t have coconut sugar on hand. Both will maintain the sweetness.
Dairy-Free Chocolate Chips
Use regular chocolate chips or carob chips if dairy-free isn’t a concern.
Rolled Oats
If oats aren’t available, you can use ground almonds (almond meal), but note the texture will be different.
