Blend the base: Add blueberries, Greek yogurt (or cottage cheese), protein powder, almond milk, vanilla, sweetener, and a pinch of salt to a blender. If using lemon zest or juice, add it now.
Adjust sweetness and thickness: Blend until silky.
Taste and add more sweetener if needed. If it’s too thick, splash in more almond milk; too thin, add a teaspoon more protein powder and blend again.
Add chia for body: Sprinkle in chia seeds and blend on low for 10–15 seconds to distribute without over-pulverizing.
Let it set: Pour into jars or bowls. Chill for at least 20–30 minutes to thicken.
For an extra-firm pudding, chill 1–2 hours.
Garnish and serve: Stir, then top with a few blueberries or a pinch of coconut flakes for texture. Enjoy cold.
