In a bowl or mason jar, combine rolled oats, cocoa powder, chia seeds, and whey protein powder. Stir well to evenly distribute the cocoa and protein powder, preventing clumps.

Mash ½ a ripe banana with a fork until mostly smooth. Add to the oats along with Greek yogurt and almond milk. Stir until fully combined. The mixture will be thick but creamy.

Fold in dark chocolate chips for that extra brownie batter vibe.

Cover your jar or container tightly and refrigerate overnight (at least 6 hours, preferably 8-12). This lets the oats soak and chia seeds thicken the mixture.

In the morning, give it a good stir. If it’s too thick, add a splash of almond milk. Top with extra chocolate chips or a drizzle of almond butter for more protein and flavor.
