Why it works
Brownie batter is the best part of making brownies and the part you're told not to eat. This one you're allowed to. Cocoa goes into the base until it's evenly brown. Chocolate chips and walnuts are folded through. Overnight, the cocoa and oats thicken into something dense and fudgy that eats a lot like batter from the bowl.
The cocoa matters
This is a three-ingredient recipe, so each one has to pull its weight. Good cocoa powder tastes deep and slightly bitter; cheap cocoa tastes like dust. Whisk it in thoroughly so there are no dry lumps. If the jar is too thick in the morning, add a splash of milk and stir.
Make it yours
A pinch of salt makes the chocolate taste more intense. A drop of vanilla makes it taste more like baking. Swap walnuts for almonds or hazelnuts. A spoon of nut butter makes it richer still. Without a DIY Oats jar, soak rolled oats overnight in milk with chia and a few almonds, then stir in the cocoa.
Storage
Covered in the fridge, it keeps for a day. It gets thicker and fudgier on day two, which some people consider an improvement.
Questions people ask
- Why are my chocolate overnight oats too thick?
- Cocoa powder absorbs liquid. Stir in a splash of milk in the morning until you get the texture you like.
- Can I make brownie batter overnight oats without chocolate chips?
- Yes. The cocoa base alone tastes chocolatey. Chips add bursts of sweetness, so add a little honey if you skip them.
- How many calories are in brownie batter overnight oats?
