Ingredients For the Oat Base & Crumble

• 2 cups rolled oats
• 1 cup oat flour
• 1 scoop (30g) vanilla protein powder
• 1 tsp baking powder
• ½ tsp cinnamon
• ¼ tsp salt
• ⅓ cup honey or maple syrup
• ¼ cup melted coconut oil or butter
• 2 large eggs
• ½ cup plain Greek yogurt
• 1 tsp vanilla extract

For the Berry Filling

• 2 cups mixed berries (fresh or frozen)
• 1 tbsp chia seeds
• 1 tbsp honey
• 1 tsp lemon juice
• 1 tsp cornstarch (optional for a thicker filling)

Step-by-Step Instructions

1. Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
2. In a medium saucepan, combine the mixed berries, honey, lemon juice, and chia seeds. Cook over medium heat for about 5–7 minutes until the berries soften and release their juices. Stir in the cornstarch if using and cook for another minute until thickened. Remove from the heat and allow the mixture to cool slightly.
3. In a large mixing bowl, whisk together the rolled oats, oat flour, protein powder, baking powder, cinnamon, and salt.
4. In another bowl, whisk the eggs, Greek yogurt, honey, melted coconut oil, and vanilla until smooth.
5. Pour the wet ingredients into the dry ingredients and stir until a thick dough forms.
6. Press about two-thirds of the oat mixture firmly into the prepared baking pan, creating an even layer across the bottom.
7. Spread the cooled berry filling evenly over the oat base, making sure it reaches the edges.
8. Crumble the remaining oat mixture evenly over the berry layer to create a rustic topping.
9. Bake for 30–35 minutes, or until the top is lightly golden and the berry filling is bubbling around the edges.
10. Allow the bars to cool completely in the pan before slicing. Chilling them for 30 minutes makes cleaner cuts and helps the filling set.
11. Store in an airtight container in the refrigerator for up to five days or freeze individually for convenient grab-and-go snacks.

Tips, Notes & Q&A

Can I use frozen berries?
Yes. Frozen berries work perfectly and do not need to be thawed first.

Can I substitute another protein powder?
Absolutely. Whey, casein, or plant-based vanilla protein powder all work well. If using an unsweetened variety, add an extra tablespoon of honey.

Can these be made gluten-free?
Yes. Simply use certified gluten-free oats and oat flour.

How should I store them?
Keep refrigerated in an airtight container. They also freeze beautifully for up to three months.

Can I add nuts or seeds?
Definitely. Chopped almonds, walnuts, pumpkin seeds, or flaxseed make excellent additions for extra crunch and nutrition.
