Absolutely delicious: Tastes like a bakery-style oatmeal chocolate chip cookie, but healthier.
INGREDIENTS YOU’LL NEED:
This simple cookie calls for a handful of nourishing ingredients you likely already have in your pantry:
Rolled oats: For that classic oatmeal cookie chewiness.
Spelt flour: Keeps it fiber-rich and wholesome (swap for whole wheat or GF flour if needed).
Peanut butter: Adds richness and nutty flavor (almond butter works too).
Oat milk: Or your favorite plant-based milk, to help bind the dough.
Coconut sugar: My go-to natural sweetener with a caramel-like taste.
Vanilla extract: A must for depth of flavor.
Baking soda: For that perfect rise.
Dark chocolate chips: The more the merrier.

HOW TO MAKE A VEGAN SINGLE-SERVE OATMEAL CHOCOLATE CHIP COOKIE:
- Stir together the wet ingredients + baking soda. Peanut butter, oat milk, vanilla extract and baking soda.
- Mix in the dry ingredients. Fold in rolled oats, flour and coconut sugar,
- Add chocolate chips. Stir in a generous amount.
- Shape & bake. Form into one thick cookie and place on a parchment-lined baking sheet. Bake at 375°F (190°C) for 10–12 minutes, until golden on the edges and soft in the center.
In just 15 minutes, you’ll have a warm, chewy, utterly satisfying cookie all to yourself.
TIPS FOR SUCCESS:
Don’t overbake. Pull out the cookie when it’s slightly golden around the edges and the center still looks a tad underdone — it will firm up as it cools.
Make it gluten-free. Use certified gluten-free oats and your favorite gluten-free flour blend.
Fun add-ins. Swap chocolate chips for raisins, walnuts, or dried cranberries for variation.
Double it. Want to share it with someone special? Just double the recipe and bake two cookies.
