Top Tips

  • Save a handful of peanuts to add crunch to the top of your peanut butter blondies. Especially if you decide to use creamy peanut butter the peanuts really add texture and depth to the blondies.
  • I’ve said it before and I’ll say it again, don’t skimp on the salt and vanilla essence. They will make your peanut butter cookie traybake come to life!
  • Pour melted dark chocolate over these blondies when they are just cooled from baking – try it and you won’t regret it.

Serving Suggestions

Hot, fresh from the oven with a drizzle of melted chocolate! I like dark chocolate to give the blondies a rich and luxurious taste but milk chocolate or even white chocolate would work too.

To level up your peanut butter tray bake into a dinner party worth dessert, serve a generously sized square of blondie with a big scoop f your favourite ice cream ( lighter flavours work best so I would choose salted caramel or your classic vanilla) and then sprinkle chocolate chips or even chocolate cover peanuts on top.

Honestly though, these blondies are so good, you’ll probably at them straight out the baking tray while they’re warm ( please don’t burn your tongue or fingers).

Substitutions and peanut blondies variations

CHOCOLATE CHIPS

If you fancy peanut butter blondies but don’t want to over do the peanuts then instead of adding salted peanuts to the recipe before baking, add a generous measure of chocolate chips. Mix these in before baking and you’ll have chocolate and peanut butter blondies.

PEANUT FREE PEANUT BUTTER BLONDIES

If like me, you aren’t the biggest fan of peanuts but love their salty flavour then use one of the many nut free PeaNOT butters. These are a nut free to the classic peanut butter, using flavourings and rice crispy treats as crunch! Perfect for your peanut averse friends or for anyone with an allergy. (ALWAYS CHECK THE LABEL)

FAQS

What is the difference between a brownie and a blondie?

The difference between a blondie and brownie is the addition of cocoa powder in the mix! Brownies have a dark and fudgey taste from the brown sugar and cocoa powder but blondies are lighter and are more akin to caramel then chocolate. They have a lovely hint of vanilla before you’ve added your flavourings.

Do salted peanuts work in blondies?

They work so well! Peanuts in blondies are like cookies and cream. The salty peanut mixed with the caramel vanilla blondie is to die fore. They add texture too, whether you’ve crunchy peanut butter or mixed in whole salted peanuts.

How is a blondie different from a cookie?

Blondies and brownies are both put into the category of cookie bars and traybakes. Blondies are softer and squidger than cookies, but have a tougher bite than a soft cake.
