Protein Bars Recipe: No-Bake Chocolate Bars
Protein bars from the supermarket can cost several dollars each, and the ingredient list is often longer than you would like. This protein bars recipe makes 12 chewy chocolate bars at home for a fraction of the price. They need no baking, come together in about 15 minutes and keep in the fridge all week, ready for lunchboxes, gym bags and afternoon snacks.
Why Make Your Own Protein Bars?
Homemade bars give you control. You choose the sweetener, the nut butter and the add-ins, and you avoid the sugar alcohols and fillers found in many commercial bars. Using a plant protein powder keeps them dairy free, while oats add fibre and a satisfying chew. They are also much cheaper per bar, especially if you make a batch every week.
The key to good bars is the balance between dry and sticky ingredients. Too dry and they crumble. Too wet and they will not hold their shape. This recipe is tested to slice cleanly.
Ingredients
Makes 12 bars
- 1 1/2 cups (135 g) rolled oats
- 3 scoops (90 g) chocolate plant protein powder
- 2 tablespoons cocoa powder
- 2 tablespoons chia seeds or ground flaxseed
- A pinch of salt
- 3/4 cup (190 g) smooth peanut butter or almond butter
- 1/3 cup (80 ml) maple syrup or rice malt syrup
- 2 tablespoons melted coconut oil
- 1 teaspoon vanilla extract
- 2 to 4 tablespoons plant milk
Chocolate topping:
- 100 g dark chocolate
- 1 teaspoon coconut oil
Method
- Line a 20 x 20 cm tin with baking paper, leaving some hanging over the sides so you can lift the slab out.
- In a large bowl, mix the oats, protein powder, cocoa, chia and salt.
- In a small saucepan over low heat, or in the microwave, warm the nut butter, syrup and coconut oil until smooth and runny. Stir in the vanilla.
- Pour the wet mixture into the dry and mix well. It should come together like a thick, slightly sticky dough. If it is crumbly, add milk a tablespoon at a time.
- Press the mixture firmly and evenly into the tin. Use the back of a spoon or a flat-bottomed glass to compact it well. This is what stops the bars falling apart.
- Melt the chocolate with the coconut oil and spread it over the top.
- Refrigerate for at least 2 hours, until firm.
- Lift out the slab and cut it into 12 bars with a sharp knife dipped in hot water.
Tips for a Protein Bars Recipe That Holds Together
- Press firmly. Compacting the mixture well is the most important step.
- Use runny nut butter. Stiff nut butter makes a dry mixture. Warm it if needed.
- Add milk slowly. Different powders absorb liquid differently. Add only what you need.
- Chill fully before cutting. Warm bars crumble at the edges.
Swaps and Variations
- Nut free: use sunflower seed butter and check that your chocolate is nut free.
- Salted caramel: use salted caramel powder, skip the cocoa and sprinkle flaky salt over the chocolate.
- Crunchy: add 1/2 cup puffed rice or chopped almonds to the dry mix.
- Fruit and nut: fold through chopped dried apricots and pistachios.
- Lower sugar: reduce the syrup to 1/4 cup and add an extra tablespoon of nut butter.
Storage
Keep the bars in an airtight container in the fridge for up to 1 week, with baking paper between layers. They also freeze well for up to 3 months. Wrap them individually, then grab one from the freezer in the morning. It will be soft enough to eat by mid-morning and keeps the rest of your lunchbox cool too.
Lunchbox and Gym Bag Ideas
Wrap each bar in baking paper and tie it with string, or keep them in a small reusable container. They travel well for a few hours out of the fridge on a mild day, so they are great for a morning at the office or a session at the gym. On hot days, pack one with an ice brick.
How Much Do They Cost?
A batch of 12 bars uses a few pantry staples you probably already own, plus three scoops of protein powder. Depending on your nut butter and chocolate, each bar typically works out much cheaper than a shop-bought protein bar. Making them every Sunday becomes a small weekly habit that saves money over time.
Quick FAQ
Do homemade protein bars need to be refrigerated? Yes. Keep them in the fridge so they stay firm, especially in warm weather.
Why are my protein bars crumbly? The mixture was too dry or not pressed firmly enough. Add a little milk and compact it well.
Can I bake this protein bars recipe? You can bake it at 170°C for 15 minutes for a firmer, flapjack-style bar, but it is designed as no-bake.
The Protein in These Bars
These bars were made with our Chocolate Flavoured Protein Powder, a plant-based powder with a rich cocoa flavour that binds well with oats and nut butter. It is dairy free and smooth, with no chalky aftertaste. Make a batch this weekend and skip the expensive supermarket bars.
