Ingredients

- Banana. Adds natural sweetness and moisture to the single serve brownie, helping to create a soft and fudgy texture.
- Flour. Provides structure to the brownie. I also add protein powder which is optional and can be replaced with equivalent amounts of flour.
- Milk. Adds creaminess and moisture to the single serve brownie.
- Maple syrup. A natural sweetener that adds depth of flavour and can be replaced with honey or agave syrup for similar results.
- Egg. Helps bind the ingredients and makes it a moist brownie.
- Cacao powder. Provides a rich chocolate brownie flavour.

How to make single serve brownie
- Mash the banana.
In a small, oven-safe pan or dish, mash the ripe banana until smooth. You could also do this in a separate bowl if you wish and then transfer to the pan once all ingredients for the single serve brownie are mixed.
- Add remaining ingredients
Add the flour, milk, protein powder, maple syrup, egg, and cacao powder directly into the pan with the mashed banana. Mix everything together until well combined, ensuring there are no lumps (but avoid overmixing to keep the single serve brownie light and fudgy).
- Bake
Place the pan in the oven and bake @180°C (350°F) for 15-20 minutes or until the brownie is set and a toothpick inserted into the centre comes out mostly clean with a few moist crumbs.
- Serve
Let the single serve brownie cool slightly before enjoying it straight from the pan or transferring it to a plate. Serve as is or with a dollop of yoghurt or your favourite toppings.

Meal prep and leftovers

Meal prepping single serve brownies with protein powder is a great way to have portion-controlled treats ready to enjoy throughout the week. You can also add in some yoghurt, fresh berries and any other toppings you want for a filling breakfast meal prep (that's absolutely delish!)
You can also mix-and-match with other similar recipes like my single serve carrot cake and small batch zucchini bread for some variety!
Storing
Keep the small batch brownies in an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days to maintain freshness.
Reheating
You can eat the small batch brownies cold, but I definitely recommend giving them a quick buzz in the microwave for 15 seconds so you get the fresh-from-the-oven brownie feel.
Freezing
Freeze small batch brownies individually by wrapping in plastic wrap, aluminium foil or baking paper, then add to freezer-safe container, ziplock bag (or you could vacuum seal them) and store for up to 6 months. Thaw at room temp or microwave.
See my post on freezing baked oats which will give you some additional tips and tricks that can be used for these small batch protein brownies.
