Ingredients

For the Oat Base & Crumble

2½ cups rolled oats
1 cup oat flour (or blended rolled oats)
2 scoops (about 60g) vanilla protein powder
½ teaspoon baking powder
½ teaspoon cinnamon
¼ teaspoon salt
⅓ cup honey or maple syrup
⅓ cup melted coconut oil or unsalted butter
1 large egg
1 teaspoon vanilla extract

Berry Filling

2½ cups mixed berries (fresh or frozen)
2 tablespoons chia seeds
2 tablespoons cornstarch
2 tablespoons honey or maple syrup
1 tablespoon lemon juice
1 teaspoon vanilla extract

Instructions

Step 1: Prepare the Oven

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal.

Step 2: Make the Berry Filling

In a saucepan over medium heat, combine the berries, honey, lemon juice, and vanilla. Cook for about 5 minutes until the berries begin to soften. Stir in the cornstarch and chia seeds, then continue cooking until the mixture thickens. Remove from heat and let it cool slightly.

Step 3: Mix the Oat Dough

In a large bowl, combine the rolled oats, oat flour, protein powder, baking powder, cinnamon, and salt. Add the honey, melted coconut oil, egg, and vanilla extract. Stir until the mixture resembles moist crumbs.

Step 4: Form the Base

Press about two-thirds of the oat mixture firmly into the prepared baking pan to create an even crust.

Step 5: Add the Filling

Spread the berry mixture evenly over the oat base, making sure it reaches the edges.

Step 6: Add the Crumble

Sprinkle the remaining oat mixture evenly over the berry layer. Gently press it down without compacting it too much.

Step 7: Bake

Bake for 30–35 minutes, or until the top is golden brown and the berry filling is bubbling around the edges.

Step 8: Cool Completely

Allow the bars to cool in the pan for at least 30 minutes, then refrigerate for another hour before slicing. This helps them hold their shape.

Tips & Notes

Frozen berries work perfectly—no need to thaw first.
Vanilla or unflavored protein powder works best.
Add chopped almonds, walnuts, or pecans for extra crunch.
For sweeter bars, drizzle a little honey over the top before serving.
Store in an airtight container in the refrigerator for up to 5 days.
Freeze individual bars for up to 3 months.

Frequently Asked Questions

Can I make these gluten-free?
Yes! Simply use certified gluten-free rolled oats and oat flour.

Can I make them vegan?
Yes. Replace the egg with a flax egg (1 tablespoon ground flaxseed + 3 tablespoons water) and use maple syrup instead of honey.

Can I use different fruit?
Absolutely. Blueberries, raspberries, strawberries, blackberries, cherries, or a combination all work beautifully.

What’s the best protein powder?
A whey isolate or plant-based vanilla protein powder blends well without making the bars dry.
