Peanut butter cornflake cakes are an old-fashioned retro refrigerator bake, that perhaps could also be classified as a cookie or possibly as a type of home-made candy or sweet. They are similar to the classic chocolate cornflake cakes and only require a few pantry ingredients - cornflakes, peanut butter, granulated sugar, golden syrup and vanilla extract.

Origin of peanut butter cornflake cakes

Peanut butter cornflake cakes share similarities to Chocolate Haystacks or Chocolate Cornflake Cakes, Rice Crispy Treats, peanut clusters, chocolate crackles, squares or slices, and the American classic Switcheroos or the festive treats Ting-A-Lings. Peanut butter cornflake cakes likely evolved from the British chocolate cornflake cake and similar cakes, and the idea to add peanut butter probably originates from the US. Although, they could also influenced by Australia's Chocolate Crackle, which are prepared with rice Krispies/rice bubble cereal, and which dates back to the 1930s.

How To Prepare

For this recipe the ingredients you will need are - cornflake breakfast cereal, peanut butter, granulated sugar, golden syrup [or an alternative syrup], vanilla extract or essence.

For this recipe we used vanilla powder which is why little vanilla speckles can be seen on the close up images, although we have also previously used vanilla extract. For a smoother texture choose a smooth peanut butter and for extra textures go with a crunchy peanut butter. The chocolate chips are optional.

Melted sugar, syrup and peanut butter poured over cornflakes in mixing bowl, with silver spoon stirring.

Step 1: Add the cornflakes to a mixing bowl.

Step 2: Place the golden syrup, granulated sugar and peanut butter into a saucepan.

Step 3: Over a low-medium heat melt the ingredients together into a smooth paste. Stir frequently and don't allow the mixture to boil.

Step 4: Remove from the heat and stir through the vanilla.

Step 5: Pour the peanut butter mixture into the cornflakes.

Melted ingredients stirred through cornflakes in bowl with spoon.

Step 6: Stir the peanut butter mixture through the cornflakes quickly until it coats the cornflakes completely.

Step 7: Using a tablespoon scoop up dollops and place on a baking tray or plate lined with baking paper.

Peanut butter cornflake cakes set out on baking tray with some cakes garnished with chocolate chips.

Step 8: Optional: Gently press in a few chocolate drops or chips.

Step 9: Place the cornflake cakes into the refrigerator and chill until set firm.

Recipe Notes

Storing

Peanut butter cornflake cakes are best stored within the refrigerator for up to 4 days possibly a day or so longer. Store the cornflake cakes within a covered container or covered plate.

Freezing

Freeze for up to 2-3 months. Wrap well with baking paper or food wrap and place in a freezer bag or container.

FAQ'S

Can I prepare these cornflake cakes as gluten-free?

Yes, the main change is to use a gluten-free cornflake breakfast cereal.

What is golden syrup?

Golden syrup is similar in colour and texture to honey, and is a popular ingredient within the UK. It is a by-product of refining sugar cane or sugar beet juice into everyday sugar. It's claimed that golden syrup was invented in England 1885, but possibly golden syrup is Australian in origin as it was recorded earlier in South Australia in 1840. Other countries may know golden syrup as light treacle.

Can I substitute the golden syrup?

The main substitute for golden syrup is light corn syrup or perhaps maple syrup. However, generally any type of syrup can be used instead of the golden syrup on a 1:1 basis. However as golden syrup is thicker than corn or maple syrup, you may need to add extra cornflakes to the mixture to soak up any excess that may occur. Although this may not be necessary. Also do bear in mind that the peanut butter cornflake cakes will taste a little different depending on which syrup is used, but of course they will still be equally tasty. Other syrups to try include rice syrup, agave syrup, or date syrup.

Can I use any variety of peanut butter for cornflake cakes?

Yes, any type of peanut butter can be used for this recipe. Also, if you prefer a crunchier nutty texture then choose a crunchy peanut butter and if a smoother texture is desired, go with a smooth, no-bits, peanut butter. Also, for a change you can replace the peanut butter with a different nut butter such as almond butter, cashew butter, hazelnut butter, etc.

I have a nut allergy. Can I substitute peanut butter for sunflower seed butter?

Technically, this recipe would work with sunflower seed butter that was the same consistency as peanut butter, but I have not tested this out so can't be 100% sure. Another option is to try peanut free WOW butter which is a toasted soya spread and looks and acts like peanut butter. It's available in Holland and Barrett health stores [UK]. Either options should work and are always worth a go.

Is white sugar vegan?

This is a question that frets many new and long-standing vegans! In the US white sugar may not be vegan as it could have been filtered using the animal ingredient bone char. However, organic, unrefined or raw white sugar is more likely to be vegan friendly. Although, in the UK white sugar is rarely prepared with bone char so is more likely to be safe for a vegan diet, but if you are concerned do some research and perhaps contact the sugar manufacturer for confirmation.

Peanut butter cornflake cakes served on a party plate with yellow flower rim, large white serving plate to background, second party plate to side, and glimpse of serving spoon, white doily background.
