Ingredients: What You’ll Need

Makes about 20–24 cookies

Dry Ingredients

• 1 cup (130 g) gluten-free 1:1 all-purpose flour blend
  • Use a blend formulated for baking
• ½ tsp xanthan gum (omit if your blend already contains it)
• 1 tsp baking soda
• ½ tsp fine sea salt
• 1 tsp ground cinnamon (optional but recommended)

Wet Ingredients

• ½ cup (113 g) unsalted butter, softened
  • Or plant-based butter for dairy-free
• ½ cup (100 g) granulated sugar
• ½ cup (100 g) packed light brown sugar
• 1 large egg, room temperature
• 2 tsp vanilla extract

Oats & Optional Add-Ins

• 1½ cups (120 g) certified gluten-free old-fashioned rolled oats
  • Do not use instant/quick oats
• Optional (choose 1 or mix):
  • ½ cup (75 g) raisins
  • ½ cup (85 g) chocolate chips (gluten-free)
  • ½ cup (55 g) chopped nuts (walnuts, pecans, almonds)

Instructions: Step-by-Step Preparation

1. Prep Pans & Oven (After Chilling)
   • Line 2 baking sheets with parchment paper.
   • You’ll preheat the oven after chilling the dough.
2. Whisk the Dry Ingredients
   • In a medium bowl, whisk together:
     • Gluten-free flour
     • Xanthan gum (if needed)
     • Baking soda
     • Salt
     • Cinnamon
   • Set aside.
3. Cream Butter & Sugar
   • In a large bowl, beat softened butter, granulated sugar, and brown sugar together on medium speed until light and creamy (about 2–3 minutes).
   • Scrape down the sides of the bowl as needed.
4. Add Egg & Vanilla
   • Beat in egg until fully incorporated.
   • Mix in vanilla extract until smooth.
5. Combine Wet & Dry
   • Add the dry ingredient mixture to the butter mixture.
   • Mix on low or stir with a spatula just until combined—no streaks of flour, but don’t overmix.
6. Stir in Oats & Add-Ins
   • Fold in gluten-free oats.
   • Fold in raisins, chocolate chips, and/or nuts if using.
   • Dough will be thick and a bit sticky.
7. Chill the Dough (Recommended)
   • Cover the bowl and chill the dough in the refrigerator for 30–60 minutes.
   • This helps the cookies hold their shape and improves texture.
8. Preheat the Oven
   • Preheat oven to 175°C.
9. Shape & Bake the Cookies
   • Scoop about 2 Tbsp of dough per cookie (a medium cookie scoop) and roll into balls.
   • Place dough balls on prepared baking sheets about 5 cm apart.
   • Gently flatten tops slightly with your fingers or the back of a spoon.
   • Bake at 175°C for 10–13 minutes, until:
     • Edges are set and lightly golden
     • Centers still look a little soft (they’ll firm as they cool)
10. Cool & Set
    • Let cookies cool on the baking sheet for 5–10 minutes.
    • Transfer to a wire rack to cool completely.

How to Store It

• Room Temperature:
  • Store in an airtight container for 3–4 days.
  • Add a small piece of bread to maintain softness.
• Freezer (Baked Cookies):
  • Freeze in a single layer, then stack with parchment between layers in a container or bag for up to 2 months.
  • Thaw at room temperature.
• Freezer (Dough Balls):
  • Freeze shaped dough balls on a tray until firm, then bag.
  • Bake from frozen at 175°C, adding 1–2 minutes to bake time.

Smart Ingredient Swaps

• Gluten-Free but Dairy-Free:
  • Use plant-based butter and dairy-free chocolate chips.
• Less Sweet Version:
  • Reduce total sugar to ¾ cup (150 g), using ½ cup brown + ¼ cup white.
• Extra Cinnamon & Spice:
  • Increase cinnamon to 1½ tsp and add a pinch of nutmeg for a warmer profile.
• Oat-Free (for those who can’t tolerate oats):
  • This recipe is oat-based by nature; you’d need a different “oatmeal-style” cookie recipe that uses coconut or quinoa flakes instead.

How to Serve It

Serve gluten-free oatmeal cookies:

• With a glass of milk (dairy or plant-based)
• Alongside coffee, tea, or hot chocolate
• On cookie platters with chocolate chip, molasses, and sugar cookies

They’re perfect for:

• Lunchboxes
• After-school or office snacks
• Holiday gift boxes and cookie swaps

Tips for Best Gluten-Free Oatmeal Cookies

• Use certified gluten-free oats to avoid cross-contamination.
• Choose a good 1:1 gluten-free flour blend formulated for baking.
• Let the dough chill—this helps control the spread and gives a chewier texture.
• Don’t overbake; pull cookies when centers still look a bit soft.

Frequently Asked Questions

Are oats naturally gluten-free?

• Oats themselves are gluten-free, but they’re often processed near wheat/rye/barley. Always use certified gluten-free oats if you’re celiac or gluten-sensitive.

Why are my gluten-free oatmeal cookies crumbly?

• Likely from too much flour or overbaking.
  • Measure flour carefully (spoon & level, don’t pack).
  • Pull cookies when edges are set, and centers are still soft.

Can I use quick oats instead of rolled oats?

• You can, but the texture will be slightly less chewy and more uniform. Rolled oats are best for that classic oatmeal cookie chew.

Can I make them vegan as well as gluten-free?

• Yes, with adjustments:
  • Use plant butter.
  • Replace egg with a flax egg (1 Tbsp ground flax + 3 Tbsp water, rested 10 minutes).
  • Note: texture will be slightly different—more tender and crumbly.
