1 scoop vanilla protein powder (25-30g)
1/3 cup plain Greek yogurt (non-fat or 2%)
1/2 cup milk of choice (almond, oat, dairy, etc.)
1 tablespoon chia seeds
1-2 teaspoons maple syrup (optional)
1/2 teaspoon vanilla extract
Pinch of sea salt

How Do You Make Overnight Oats That Are Perfectly Thick?

The secret to achieving that perfect thick overnight oats recipe texture lies in the ratios and technique:

Step 1: Layer Your Dry Ingredients

In a mason jar or container, combine oats, protein powder, chia seeds, and any spices. This prevents clumping and ensures even distribution.

Step 2: Create the Perfect Liquid Base

Whisk together milk, Greek yogurt, maple syrup, and vanilla extract in a separate bowl. This creates a smooth, creamy base that won’t leave protein powder chunks.

Step 3: Combine and Mix Thoroughly

Pour the liquid mixture over the dry ingredients. Stir vigorously for 30 seconds, then cover and shake if using a jar. This is crucial for preventing lumps!

Step 4: The Double-Mix Method

After 10 minutes in the fridge, give everything another good stir. This ensures the chia seeds don’t clump together and creates the perfect consistency.

Step 5: Overnight Transformation

Refrigerate for at least 4 hours or overnight. The oats will absorb the liquid and become creamy and thick – perfect for scooping!
