Missing the classic oatmeal taste while on a low-carb diet? These Keto Oatmeal Cookies bring the chewy texture and buttery taste of traditional oatmeal cookies without tons of sugar. Instead of oats, we use unsweetened coconut flakes or hemp hearts to mimic the texture of oats. These are perfect for breakfast, snacking, or dessert—all without the carb overload.

Preparation and Cooking Overview

Making these cookies is a breeze and only takes 30 minutes. Mix the dry and wet ingredients separately, then combine to form a cookie dough. Scoop onto the baking sheet, flatten slightly, and bake for 12-16 minutes until golden brown.

Chef's note

For a softer cookie, let the dough sit for 10 minutes before baking. If you prefer crunchier cookies, bake them for an extra 2-3 minutes. Customize by mixing in sugar-free chocolate chips, chopped nuts, or dried cranberries for extra texture and flavor. If you prefer a nut-free version, swap almond flour for sunflower seed flour and use hemp hearts instead of coconut.

Chef's pro tip

If your cookies turn out too dry or crumbly, the dough might be too dry due to over-measuring almond flour or not enough moisture from butter and egg. To fix this, add a teaspoon of unsweetened almond milk or an extra egg yolk to bring back the right consistency. Also, avoid overbaking—remove them from the oven when the edges turn golden brown, as they continue to firm up while cooling.

What to Serve with Keto Oatmeal Cookies

  • Keto coffee or tea: A warm cup of keto-friendly coffee or tea enhances the buttery, spiced flavors of the cookies, making for a cozy pairing.
  • Sugar-free almond milk: A cold glass of unsweetened almond milk provides a creamy contrast and is perfect for dipping the cookies.
  • Greek yogurt with berries: Crumbling the cookies over keto-friendly Greek yogurt and fresh berries creates a delicious, high-protein snack with added texture.
  • Melted sugar-free chocolate: Dipping the cookies in melted sugar-free chocolate adds an extra layer of sweetness and richness.
  • Whipped cream or mascarpone: Serving these cookies with a dollop of sugar-free whipped cream or mascarpone makes for a satisfying, indulgent dessert.

How to Make It Healthier

To make the cookies even healthier, you can reduce the sweetener slightly and add more fiber by incorporating flaxseed meal or chia seeds.

Time-Saving Tips

  • Use pre-shredded coconut to save minutes of prep time.

What Can I Prepare Ahead of Time?

  • The cookie dough mixture can be made ahead of time and stored in the fridge for up to 3 days. When ready to bake, simply shape the dough into balls and place them on parchment-lined cookie sheets.
  • You can also freeze unbaked cookie dough balls for up to 3 months. To bake from frozen, place frozen dough balls directly on the baking tray and add 1-2 extra minutes to the baking time.

Storage and Reheating Instructions

Storage Instructions

  • Store in an air-tight container at room temperature for up to 5 days.

Reheating Best Instructions

  • Microwave for 10-15 seconds for a soft texture.
