Zest the orange: Use a fine grater to remove the bright orange zest. Avoid the white pith—it’s bitter.
Mix dry ingredients: In a jar or bowl, combine 1/2 cup rolled oats, 1 tablespoon chia seeds, 1 tablespoon cocoa powder, and a pinch of salt.
Stir to distribute evenly.
Add protein: Stir in 1 scoop chocolate protein powder. If your powder is very sweet, plan to reduce the maple syrup later.
Whisk the wet base: In a separate cup, whisk 1/2 cup milk, 1/4 cup Greek yogurt, 1–2 teaspoons orange zest, 1–2 teaspoons maple syrup, 1/2 teaspoon vanilla extract (optional), and 1–2 teaspoons fresh orange juice.
Combine: Pour the wet mixture over the dry. Stir well, scraping the edges so no dry pockets remain.
Adjust consistency: The mixture should be loose, like a thick batter.
Add a splash more milk if it’s too dense—chia will thicken it overnight.
Chill: Cover and refrigerate for at least 4 hours, preferably overnight.
Finish and top: In the morning, stir and assess thickness. Add a bit more milk if needed. Top with dark chocolate shavings, orange slices, and nuts if you like.
Serve cold or warm: Eat straight from the fridge, or warm gently in the microwave with a splash of milk for 30–45 seconds.
