Blueberry Oat Bars

Blueberry Oat Bars — soft, chewy, vegan, gluten-free, and protein-packed — are proof that “healthy” doesn’t have to be boring. I brought a batch to a picnic last weekend, and they disappeared faster than the chips! Honestly, I prefer them to store-bought bars any day.
If you love easy, wholesome desserts that taste like a treat, you’re going to adore this one.

Overview of Recipe Content

What Are Blueberry Oat Bars?

Think of these bars as the perfect blend between a soft oatmeal cookie and a fruity crumble. They’re chewy at the base, bursting with juicy blueberries in the middle, and lightly crisp on top.

Perfect for meal prep, picnics, lunchboxes, or an afternoon pick-me-up.

Why You’ll Love Them

  • Vegan & Gluten-Free: Made with oat flour and coconut oil—no dairy, no eggs.
  • High in Protein: Thanks to oats and nut butter.
  • One Bowl Recipe: Less mess, more yum.
  • Naturally Sweetened: Maple syrup gives that warm, caramel note.
  • Perfect Texture: Soft, chewy, and a little jammy in the center.

What It Tastes Like

Each bite is a cozy hug: sweet from the blueberries, nutty from oats, and just the right amount of crumble on top.

Seasonal Note

Best made when blueberries are at their juicy summer peak, but frozen berries work beautifully too!

Ingredient List

This Now, Make It Later!
  • 2 cups rolled oats (use certified gluten-free if needed)
  • 1 cup oat flour (blend oats until fine)
  • ½ cup almond butter or peanut butter
  • ½ cup maple syrup or honey
  • ¼ cup melted coconut oil
  • 1 tsp vanilla extract
  • 1 ½ cups blueberries (fresh or frozen)
  • 1 tbsp cornstarch
  • 1 tbsp lemon juice
  • Pinch of salt

Tools You’ll Need

  • Mixing bowls
  • 8×8 baking pan
  • Parchment paper
  • Spatula or spoon

Suggested Substitutions

  • Swap almond butter for sunflower seed butter to make it nut-free.
  • Try raspberries or blackberries for a flavor twist.
  • Add a sprinkle of shredded coconut for extra chew.

How to Make Blueberry Oat Bars

Step 1: Prep Your Pan

Line your 8×8 baking pan with parchment paper and preheat your oven to 350°F (175°C).

Step 2: Mix the Dry Ingredients

In a large bowl, combine rolled oats, oat flour, and salt. Give it a quick stir.

Step 3: Combine the Wet Ingredients

In a separate bowl, whisk together almond butter, coconut oil, maple syrup, and vanilla until smooth and glossy.

Step 4: Combine & Create the Base

Pour the wet mixture into the dry and stir until crumbly but sticky. Press two-thirds of the mixture into the baking pan—this forms your delicious chewy base.

Step 5: Make the Blueberry Filling

In another bowl, mix blueberries with cornstarch and lemon juice. Spoon the mixture evenly over your oat base.

Step 6: Crumble & Bake

Sprinkle the remaining oat mixture on top and lightly press. Bake for 25–30 minutes until golden and fragrant.

Step 7: Cool & Slice

Let cool completely before slicing—this helps them set. Then cut into bars and devour!

Pro Tip: A chilled bar straight from the fridge hits differently on a hot day!

What to Serve with Blueberry Oat Bars

These bars pair beautifully with:

  • A cup of iced matcha latte
  • A spoonful of Greek yogurt for breakfast
  • A drizzle of warm almond butter for dessert vibes

Or pack them for a hike with your favorite Protein Cookie Dough (see recipe here) — the combo is unbeatable!

Tips for Making It Perfect

  • Don’t overmix: Gentle folding keeps them tender.
  • Cool before slicing: They firm up as they rest.
  • Use parchment: Makes removing them a breeze.
  • Freeze extra: They keep beautifully for quick snacks.

Storage Instructions

  • Room Temp: 2–3 days in a sealed container.
  • Fridge: Up to 1 week.
  • Freezer: Up to 3 months—layer with parchment between bars.
  • To serve, thaw in the fridge or microwave for 10 seconds.
