💗 Why This Recipe Works
✅ 5-Ingredient - Just bananas, oats, cocoa, cinnamon, and vegan chocolate transform into dessert perfection
✅ Naturally Sweetened - Ripe bananas provide all the sweetness (no refined sugar needed!)
✅ Allergy-Friendly - Vegan, gluten-free (use certified GF oats), and nut-free options
✅ No Oven Needed - Perfect for hot days or tiny kitchens. Just like this, an easy vegan dessert without an oven
✅ Meal Prep Hero - Stays fresh for 4 days (if it lasts that long!)
Secret Weapon: The oat-banana combo creates a surprisingly cake-like texture without flour or eggs.
🥧 Ingredients
*See the recipe card for full information on ingredients and quantities.
- Ripe bananas: Look for lots of brown spots (the riper, the sweeter). Can substitute ½ cup applesauce if needed. Use them also in my brown butter maple walnut banana bread.
- Cocoa powder: Use natural (not Dutch-process) for the best flavour. For extra richness, add 1 tablespoon nut butter.
- Oatmeal: Rolled oats work best (quick oats will make it denser). For gluten-free, use certified GF oats.
- Vegan chocolate: 70% dark chocolate works perfectly. Chop roughly for easier melting.
- Sunflower oil: Any neutral oil works (canola, vegetable). Can omit if using a non-stick pan.
- Cinnamon (optional): Adds warmth without sweetness. Try cardamom or pumpkin spice for variation.
♻️ Substitutions
- Ripe Bananas - If you don't have ripe bananas, you can use mashed avocados for a creamy texture and natural sweetness.
- Ground Cinnamon - If you're not a fan of cinnamon, you can skip it or try a pinch of nutmeg for a different warm flavour.
- Cocoa - No cocoa on hand? Swap it with carob powder for a chocolate-like taste.
- Oatmeal - Rolled oats work well, or if you're looking for a gluten-free option, try quinoa flakes.
- No Vegan Chocolate - use vegan chocolate chips. Many brands offer chocolate chips made without dairy. Also, dark chocolate is good; look for dark chocolate that doesn't contain any dairy.
- Sunflower Oil - Any neutral-flavoured oil, like canola or vegetable oil, can be used.
- Chopped Nuts - If you have allergies or prefer a different texture, try toasted coconut flakes or seeds like pumpkin or sunflower seeds.
📖 Variations
- Nutty Bliss: Stir in ¼ cup chopped walnuts or pecans into the batter. Toasting the nuts first brings out their rich flavour and adds a wonderful crunch.
- Berry Burst: Layer fresh raspberries or strawberries between the banana-oat mixtures. The bright, tart berries cut through the sweetness beautifully.
- Salted Caramel: Drizzle with vegan caramel sauce and flaky salt before serving. Quick hack: Mix 2 tablespoon date syrup with 1 tablespoon nut butter for instant "caramel."
- Warm Spices: Add ½ teaspoon cinnamon + ¼ teaspoon nutmeg to the dry ingredients. Perfect for fall! Pairs wonderfully with the chocolate.
- Tropical Twist: Mix in ⅓ cup toasted coconut flakes and 2 tablespoon diced pineapple. Pro tip: Pat the pineapple dry first to prevent sogginess.
- Citrus Zing: Add 1 teaspoon orange or lemon zest to the filling. The bright citrus notes balance the rich chocolate flavour.
👩🍳 How To Make Vegan, No-Bake Dessert!
This no-bake banana cake might look like a complicated dessert, but it's super quick and easy to make. It's the kind of treat that makes you feel like a pro in the kitchen without any hassle!
Step 1: In a large mixing bowl, mash the ripe bananas until smooth. Add the cinnamon, cocoa powder, and oatmeal, and mix everything thoroughly until well combined.
Step 2: Press half of the banana-oat mixture into the cake pan, packing it down firmly. Add a layer of sliced bananas, then cover completely with the remaining banana-oat mixture.
Step 3: Melt the chocolate, then pour and spread it evenly over the cake. Add chopped nuts on top if you like. Cover the pan and chill for a minimum of 2 hours until the cake is fully firm.
Step 4: Serve: When you're ready to serve, let it sit at room temperature for 10-15 minutes to soften slightly. Enjoy!

Pro Tip: For ultra-creamy texture, blend the oats into a fine flour first! This creates a smoother cake that holds together better when sliced.
❓5-Ingredient Vegan No-Bake Cake FAQs
You can! While cocoa adds a chocolaty twist, you can leave it out if you prefer a classic banana flavour.
No worries! If you're out of oatmeal, you can use other rolled grains like quinoa flakes or even crushed graham crackers.
Sure thing! If you don't have sunflower oil, you can substitute it with another mild vegetable oil like canola or grapeseed oil.
Of course! If you don't have a 16 cm cake pan, you can use a similar-sized pan or even a square one. Just adjust the layer thickness accordingly.
Place the cake in an airtight container or wrap it well in plastic wrap, then store it in the fridge where it'll stay fresh for 4 to 5 days. For longer storage, freeze individual slices in freezer-safe bags or containers-they'll keep well for a couple of months.
