Oatmeal Cookie Bars

First off, thank you so much for being here—I’m thrilled to share this cozy little treat with you today! These gluten-free oatmeal cookie bars aren’t just sweet and fudgy, they’re the kind of dessert that makes the whole kitchen smell like love. When I baked a batch for my mom last weekend, she leaned in, took a deep breath, and said: “These smell better than any candle.” Honestly? She’s right!

If you love easy desserts with big flavor, this one will become a staple in your kitchen. Oh, and my mom even declared she prefers these over pumpkin pie… and that’s saying something!

Overview of Recipe Content

These cookie bars are:

  • Perfect for gatherings – Quick to whip up, slice, and share.
  • Naturally gluten-free – Oats and almond flour give the perfect chewy texture.
  • Fudgy & soft inside, golden outside – like the best mix between a brownie and an oatmeal cookie.

What they taste like: Imagine a chewy oatmeal cookie with a slight nuttiness, but in a bar form, thick enough to sink your teeth into, with melty chocolate in every bite.

Nutritional benefits: Thanks to oats and almond flour, they’re higher in fiber and protein than your average dessert. Plus, they can be made dairy-free too.

Ingredients you’ll need:

This Now, Make It Later!
  • 2 cups gluten-free rolled oats
  • 1 cup almond flour
  • ½ cup brown sugar (or coconut sugar)
  • ½ cup maple syrup or honey
  • ½ cup unsalted butter (or coconut oil), melted
  • 2 eggs
  • 1 tsp vanilla extract
  • 1 tsp baking soda
  • ½ tsp cinnamon
  • ¼ tsp salt
  • 1 cup dark chocolate chips

Tools you’ll need:

  • Mixing bowls
  • Whisk & spatula
  • 8×8-inch baking pan
  • Parchment paper

Substitutions & Additions:

  • Swap almond flour for oat flour if needed.
  • Add chopped pecans or walnuts for crunch.
  • Use dried cranberries or raisins instead of chocolate chips.
  1. Preheat & Prep – Heat oven to 350°F (175°C). Line your baking pan with parchment for easy removal.
  2. Mix Wet Ingredients – In a bowl, whisk melted butter, sugar, syrup, eggs, and vanilla until glossy.
  3. Combine Dry Ingredients – In another bowl, stir oats, almond flour, baking soda, cinnamon, and salt.
  4. Bring It Together – Slowly fold the dry mix into the wet mix until fully combined. Stir in chocolate chips.
  5. Bake – Spread evenly into pan and bake for 20–25 minutes, until golden and slightly set in the center.
  6. Cool & Slice – Let cool completely before slicing into bars (trust me, it’s worth the wait!).

These bars come out chewy, sweet, and oh-so-satisfying. The smell alone will have everyone running to the kitchen!

  • A warm mug of chai or hot chocolate.
  • A scoop of vanilla ice cream for dessert.
  • Fresh berries on the side for a lighter bite.

Tips for Making It Perfect

  • Don’t overbake! Pull them out when the edges are golden but the center still looks a little soft.
  • Chill before slicing if you want clean, bakery-style bars.
  • Double the batch—these go fast, especially at potlucks or family gatherings.

Storage Instructions

  • Room Temp: Store in an airtight container up to 4 days.
  • Fridge: Keeps for 1 week, great for meal prep.
  • Freezer: Wrap individually and freeze up to 3 months. Defrost at room temp or microwave for 20 seconds.
