Banana Oat Cookies No Sugar No Flour (5 Ingredients, Naturally Sweet)

Sometimes the simplest recipes turn out to be the ones you make on repeat, and these banana oat cookies are exactly that. No sugar, no flour, no fuss. They come together in one bowl, bake in under 15 minutes, and honestly taste more satisfying than a lot of traditional cookies you would find in a bakery. If you have been searching for a snack that ticks all the boxes, a treat that feels indulgent but is actually doing something good for your body, this is it. Kids love them, adults sneak them straight off the cooling rack, and they work just as well as a grab-and-go breakfast as they do a mid-afternoon snack.
The magic of this recipe really does start with the bananas. You want them very ripe, the ones with plenty of brown spots that you might otherwise think are past their best. Those overripe bananas are sweeter, softer, and mash down into a natural binding syrup that holds everything together without a single gram of added sugar. Rolled oats are the backbone here, providing slow-release complex carbohydrates and a generous dose of beta-glucan fibre, which research consistently links to better cholesterol levels and steadier blood sugar. To those two hero ingredients, we add a spoonful of natural almond butter for healthy monounsaturated fats and protein, a pinch of cinnamon for warmth and its own blood-sugar-friendly properties, and a handful of dark chocolate chips because life is short and 70 percent cocoa solids are genuinely good for you. Every single ingredient earns its place.
The texture is soft and slightly chewy in the centre with just a little golden crispness on the edges, somewhere between a flapjack and a traditional cookie. They smell incredible as they bake, like a warm banana bread has wandered into your kitchen uninvited. Straight from the oven they are soft and pillowy, and after cooling for ten minutes they firm up to a more satisfying bite. Try them warm with a small pot of natural yoghurt for breakfast, or pack a couple into a lunchbox alongside a piece of fruit. A cup of black coffee or a chai latte alongside a cooled cookie is a seriously underrated afternoon moment. You can also press a few extra dark chocolate chips into the tops just before baking if you want to make them look as good as they taste.
From a nutritional standpoint, these cookies are a genuinely wholesome choice rather than a compromise. Each cookie comes in at around 95 calories, with nearly 2 grams of fibre and a solid hit of potassium from the banana. Because the sweetness comes entirely from fruit, the sugar content is naturally lower than anything made with refined white sugar or even most natural syrups. The oats are naturally gluten free if you source certified gluten free oats, making these suitable for people managing a gluten sensitivity. They are also completely dairy free, egg free, and vegan friendly, so they work for a wide range of dietary needs without requiring any awkward swaps. The almond butter brings protein and healthy fats that help slow digestion and keep you feeling full, which is the kind of detail that separates a genuinely healthy snack from something that just looks healthy on the label. These banana oat cookies with no sugar and no flour prove that eating well does not have to mean eating boringly.
Ingredients
- 3 large very ripe bananas (heavily spotted for maximum natural sweetness)
- 2 cups rolled oats (use certified gluten free oats if needed)
- 2 tbsp natural almond butter (smooth, no added sugar or salt)
- 1 tsp ground cinnamon
- 3 tbsp dark chocolate chips (70 percent cocoa or higher, dairy free if needed)
Instructions
- 1
Heat your oven to 180 C (350 F) and line a large baking sheet with parchment paper. Give the paper a very light spray of cooking oil just to be safe.
Parchment paper is non-negotiable here. These cookies have no butter or oil in the dough, so they will stick to an unlined tray.
- 2
Peel the bananas and place them in a large mixing bowl. Mash thoroughly with a fork until you have a smooth, lump-free puree. A few tiny lumps are fine, but the smoother the better for even binding.
If your bananas are slightly firm, microwave them (unpeeled) for 30 seconds first to soften them faster.
- 3
Add the almond butter and ground cinnamon to the mashed banana. Stir everything together until fully combined and the almond butter is completely incorporated with no streaks remaining.
- 4
Add the rolled oats and fold them through the banana mixture using a wooden spoon or silicone spatula. Mix until all the oats are coated and the mixture holds together when pressed. It will be sticky and thick, which is exactly right.
Do not use instant oats here. They absorb too much moisture and produce a gluey, dense result. Rolled oats give you the right texture.
- 5
Fold in two thirds of the chocolate chips, saving the rest to press on top. This gives you chocolate throughout the cookie and a few visible chips on the surface.
- 6
Scoop heaped tablespoons of the mixture onto the prepared baking tray, spacing them about 4 cm apart. Gently flatten each mound with the back of a damp spoon to roughly 1 cm thick. These cookies do not spread during baking, so shape them how you want them to look.
A cookie scoop gives you uniform portions and means all the cookies bake at the same rate.
- 7
Press the remaining chocolate chips onto the tops of each cookie, then transfer the tray to the centre of the oven. Bake for 12 to 14 minutes, until the edges are golden and the tops look set and no longer glossy.
Check at 12 minutes. Oven temperatures vary, and you want them just done rather than overdone. They firm up considerably as they cool.
- 8
Remove from the oven and leave the cookies to cool on the tray for 10 minutes before moving them to a wire rack. They will be very soft straight from the oven but firm to the perfect chewy texture as they cool.
Resist moving them too early. They need those 10 minutes on the tray to set properly, or they may crumble.

Pro Tips
- ✓
The riper the banana, the sweeter and more flavourful your cookies will be. Black-spotted bananas work best.
- ✓
If your mixture feels too wet to hold a shape, add an extra 2 tablespoons of rolled oats and let the mixture sit for 3 minutes to absorb the moisture.
- ✓
For extra flavour depth, add half a teaspoon of pure vanilla extract with the almond butter.
- ✓
These cookies freeze brilliantly. Freeze them in a single layer, then transfer to a bag. Reheat from frozen in a 160 C oven for 6 minutes.
- ✓
To make them nut free, swap the almond butter for sunflower seed butter. The flavour is slightly different but the texture stays the same.
- ✓
Pressing the cookie dough down before baking is important. Thick mounds will stay soft and slightly underdone in the centre.
Frequently Asked Questions
Variations
- •
Peanut Butter Banana Oat Cookies
Swap the almond butter for natural peanut butter and add a pinch of sea salt on top before baking. The salty-sweet combination is seriously addictive and the cookies come out slightly denser with a stronger nutty flavour.
- •
Berry and Coconut
Replace the chocolate chips with 3 tablespoons of dried cranberries or chopped dried mango, and fold in 2 tablespoons of desiccated coconut. Great for a tropical spin that works brilliantly with the banana base.
- •
Spiced Raisin
Skip the chocolate and use 3 tablespoons of raisins instead. Increase the cinnamon to 1.5 teaspoons and add a quarter teaspoon each of ground ginger and nutmeg. These taste like a healthier version of an oatmeal raisin cookie and are wonderful with tea.
- •
Seed and Hemp Boost
Add 2 tablespoons of hemp seeds and 1 tablespoon of chia seeds to the mix along with the oats. This version is higher in omega-3 fatty acids and protein, making it an excellent post-workout snack.
Substitutions
- •Almond butter → Sunflower seed butter (Keeps the recipe nut free with a similar creamy texture. The flavour is slightly more earthy but works well with banana and cinnamon.)
- •Almond butter → Tahini (Gives a slightly bitter, sesame-forward flavour that pairs surprisingly well with banana. Use the same quantity.)
- •Dark chocolate chips → Carob chips (Naturally caffeine free and slightly sweeter than dark chocolate. A good option for young children or those avoiding caffeine.)
- •Ground cinnamon → Mixed spice or pumpkin spice blend (A quarter teaspoon of mixed spice gives a more complex warming flavour. Do not use more than this as the blend can overpower the banana.)
🧊 Storage
Store cooled cookies in an airtight container at room temperature for up to 4 days. For longer storage, keep them in the fridge for up to 7 days or freeze in a single layer for up to 3 months. Thaw at room temperature for 20 minutes or warm in a low oven for 5 to 6 minutes.
📅 Make Ahead
The cookie dough can be mixed up to 24 hours in advance and stored covered in the fridge. When ready to bake, scoop and flatten onto the lined tray and bake as directed, adding an extra minute to the bake time since the dough will be cold.
