Kitchen Tools Needed

Mixing bowl
Spatula
8×8-inch (20×20 cm) pan
Parchment paper
Measuring cups/spoons

No blender required!

Step-by-Step Preparation

Step 1: Prepare the Pan

Line an 8×8-inch pan with parchment paper, leaving overhang for easy lifting.

Step 2: Mix Dry Ingredients

In a large bowl, combine:

Rolled oats
Protein powder
Chia seeds
Sea salt

Stir well to distribute evenly.

Step 3: Mix Wet Ingredients

In a separate bowl, whisk together:

Almond butter
Maple syrup
Melted coconut oil
Vanilla

Mixture should be smooth and glossy.

Step 4: Combine

Pour wet ingredients into dry ingredients.

Stir until fully combined.

Fold in dried blueberries.

Texture cue: The mixture should feel thick and slightly sticky but hold together when pressed.

If too dry, add 1–2 tablespoons plant milk.
If too wet, add 1–2 tablespoons oats.

Step 5: Press & Chill

Transfer mixture into lined pan.

Press firmly and evenly using the back of a spoon (or your hands).

Chill in refrigerator for at least 1 hour.

This step is key — it allows chia seeds to bind everything together.

Step 6: Slice & Enjoy

Lift out using parchment paper.

Slice into 8 even bars.

Store chilled until ready to eat.

Expert Tips & Mistakes to Avoid

1. Use Thick Nut Butter

Runny nut butter can make bars too soft.

2. Press Firmly

Compact bars tightly so they don’t crumble.

3. Let Them Chill Fully

Rushing this step leads to crumbly texture.

4. Choose Quality Protein Powder

A chalky protein powder affects taste and texture.

5. Balance Moisture

If using fresh blueberry puree, reduce maple syrup slightly.
