NO-BAKE PEANUT BUTTER OAT BARS
Makes: 10–12 bars
Prep time: 10 minutes
Chill time: 1 hour
INGREDIENTS
180g rolled oats
150g soft pitted dates
120g smooth peanut butter
60ml honey or maple syrup
40g chopped nuts, such as almonds, walnuts or cashews
25g mixed seeds, such as pumpkin seeds, sunflower seeds or chia seeds
30g dark chocolate chips or chopped dark chocolate, optional
½ tsp vanilla extract
A pinch of salt
METHOD
- Line a loaf tin or small square tin with baking paper, leaving a little overhang at the sides. This makes it much easier to lift the bars out once chilled.
- Add the pitted dates to a food processor and blend until they form a sticky paste. If your dates are dry or firm, cover them with hot water for 10 minutes first, then drain well before blending.
- Add the oats, chopped nuts, seeds, chocolate chips, if using, and salt to a large mixing bowl. Stir everything together.
- Add the peanut butter, honey or maple syrup and vanilla extract to a microwave-safe bowl or small saucepan. Warm gently until the mixture is runny and easy to stir. You do not need to make it hot — just warm enough to loosen it.
- Add the blended date paste and warm peanut butter mixture to the bowl of dry ingredients. Mix really well until all of the oats are coated and the mixture begins to stick together.
- Tip the mixture into the lined tin. Place another piece of baking paper over the top and press the mixture down firmly using your hands, the bottom of a glass or a measuring cup.
- Chill in the fridge for at least 1 hour, or in the freezer for around 30 minutes if you are short on time.
- Lift the chilled mixture out of the tin, slice into bars and enjoy.
TOP TIPS
Use soft dates
Soft, sticky dates work best because they help bind the bars together. Medjool dates are lovely for their soft, caramel-like texture, but any pitted dates will work — just soak dry ones first.
Press them down firmly
This is the most important step. Spend an extra minute really pressing the mixture into the tin, especially around the edges. If it is loose before chilling, it is more likely to crumble once sliced.
Adjust as needed
If your mixture seems dry, add an extra spoonful of peanut butter, honey or maple syrup. If it feels very sticky, add a small handful of extra oats. Nut butters and dates can vary, so it is fine to adjust the texture slightly.
FLAVOUR SWAPS
Chocolate Orange
Add the zest of 1 orange and use dark chocolate chips.
Coconut Crunch
Mix in 30g desiccated coconut.
Fruity Flapjack
Swap the chocolate chips for 50g raisins, dried cranberries or chopped dried apricots.
Nut-Free
Use sunflower-seed butter instead of peanut butter and replace the chopped nuts with extra seeds.
Vegan
Use maple syrup instead of honey.
Protein Boost
Add 20–30g vanilla protein powder. If the mixture becomes too dry, add 1–2 tbsp milk.
Apple and Cinnamon
Add ½ tsp ground cinnamon and 40g finely chopped dried apple.
HOW TO STORE NO-BAKE OAT BARS
Store the bars in an airtight container in the fridge for up to 1 week.
For longer storage, wrap the bars individually and freeze for up to 2 months. Let a frozen bar sit at room temperature for 10–15 minutes before eating, or add one to your lunchbox in the morning.
FREQUENTLY ASKED QUESTIONS
Can I make these without a food processor?
Yes. Use very soft dates, chop them as finely as possible and mash them with a fork. It will take a little longer, but the bars will still work. Ready-made date paste is another handy option.
Can I use quick oats?
Yes. Quick oats will work and give the bars a slightly softer texture. Rolled oats create a chewier, more flapjack-style bar.
Can I use a different nut butter?
Absolutely. Almond butter, cashew butter and hazelnut butter all work well. Use a smooth, runny nut butter for the best result. Sunflower-seed butter is a great nut-free alternative.
Can I eat these for breakfast?
Definitely. Enjoy one alongside Greek yoghurt and fruit for a more filling breakfast, or grab one as an easy snack between meals.
These no-bake peanut butter oat bars are simple, satisfying and perfect for easy snack prep. With just a few cupboard staples, one bowl and a little time in the fridge, you’ll have a batch of chewy homemade bars ready for the week ahead.
