🛒 Ingredient notes

When it comes to making no-bake chocolate peanut butter bars, the ingredient list is relatively short and straightforward.
For the crunchy peanut butter base layer;
Peanut Butter - use smooth or crunchy, it doesn't matter!
Golden Syrup - helps the base layer stick together and gives the bars a lovely caramel sweetness. You can also use honey.
Sugars - I like to use a combination of light brown sugar and white caster sugar for the best texture and taste.
Crunchy Nut Cornflakes - gives the bars a delicious crunch. You could also use regular cornflakes or even rice krispies.
For the chocolate topping;
Chocolate - a combination of milk and dark chocolate, broken into pieces and melted.
Oil - a drop of vegetable oil prevents the top from cracking when cut with a knife.
🔪 Instructions
This recipe requires no baking and can be made quickly with just a few simple ingredients.
The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post
One: Line a 20cm (8") square tin with cling film (plastic wrap).
Two: In a large saucepan melt together the peanut butter, golden syrup, and sugars over low heat.
Three: Mix in the crushed crunchy nut cornflakes and mix to combine.
Four: Spoon the peanut butter base layer into the tin and press it down firmly with the back of a heavy spoon.

Five: Melt the chocolate pieces and a drop of vegetable oil in the microwave until glossy and smooth. I microwave in 30-second bursts and stir, to avoid overcooking the chocolate.
Six: Spread the melted chocolate onto the peanut butter layer and sprinkle with chocolate chips.
Seven: Chill for 2 hours before cutting into squares.

💭 Expert tips
- Use good quality chocolate and peanut butter, as they will greatly affect the final taste and texture of the bars.
- Lining the tin is very important as you don't want the bars to stick!
- It's important to chill the bars for at least 2 hours before cutting them into squares. This will help them firm up and hold their shape. I like to chill them in the fridge overnight for the best results.
- Use a long sharp knife to cut neat squares and clean the knife off between each cut (be careful when doing this).
🍴 Serving suggestions
Serve the no-bake peanut bars for a sweet treat with a cup of tea, cup of coffee, or a glass of cold milk. They make great after-school snacks, and you can even serve them at parties and bake sales.

📖 Variations
- For a crunchier textured base layer, add in some chopped peanuts.
- Swap the chocolate topping for some drizzled melted peanut butter instead.
- Add 100g of chocolate chips into the base layer for a more chocolatey taste.
- Mix in 2 teaspoons of vanilla extract to the base layer for more flavour.
🥡 Storage
Store - If it's not too hot, you can store your bars at room temperature, in an airtight container. This will help prevent them from drying out and becoming stale. However, keep in mind that storing your bars at room temperature for too long can cause the chocolate to melt and the bars to become soft. Therefore, it's best to consume them within a few days of making them. If it's warm, store them in the fridge instead.
Freeze - To freeze your bars, wrap them tightly in cling film (plastic wrap) and then place them in an airtight container or freezer bag. They will keep well in the freezer for up to 3 months. When you're ready to enjoy them, simply let them defrost at room temperature for a few hours before serving.
