Peanut Butter Blondies with White Chocolate – A recipe borrowed from ‘Cake Angels’
These Peanut Butter Blondies were my first attempt at blondie-making… and actually, blondie-eating! I first posted them on the blog way back in 2013. At that time, and having no idea what a blondie should actually be like, I decided to use someone else’s recipe. I needed to get a feel for how they ‘should’ be and ‘should’ taste.
I had on my shelf a copy of ‘Cake Angels – Gluten, Wheat & Dairy Free Cakes’ by Julia Thomas. It’s a great book with all cakes being both gluten and dairy free. If you haven’t seen it, I would definitely recommend it. We actually have another recipe from the same book adapted on the blog (a Chocolate Fudge Cake made by Miss GF), which is equally divine.
Anyway… the book has an incredibly simple and extremely quick recipe for gluten free peanut butter blondies. And since we love peanut butter at GFHQ, it seemed a great place to start our blondie exploration.
Having made them, they were so good, that there then seemed little point in messing further. So, the recipe for the gluten free blondies presented here is pretty much as in the book. The key difference being that as we aren’t dairy free, they are made with good old-fashioned butter (and some extra dairy-based chocolate). And I’ve used my Gluten Free Alchemist flour blend A to make them. If you can’t eat dairy, just do a straight substitution and use dairy free spread and dairy free chocolate instead. They should work with other flour blends too.




What is a Blondie?
To the uninitiated, a blondie is just a light-coloured brownie right? Wrong! They have lots in common, but there are also important differences. Yes… they both have an amazing fudgy, dense texture (somewhere between a cake and a cookie). And yes… they are both ‘tray-baked’ and cut into squares. But a blondie is not just a ‘blonde’ brownie.
Although both have similar ingredients lists, a basic blondie recipe contains no chocolate. Instead, it uses brown sugar and vanilla for flavour and texture. Carefully balanced, the combination used still produces the same squidgy-chewy texture that you find in a brownie. And you can still expect rich, bite-sized chunks of yumminess. But blondies offer an amazing backdrop of ‘butterscotch’ that comes from brown sugar rather than chocolate.
So, what if you do add melted white chocolate to the mix? Wouldn’t that be a blondie? Apparently not. What you then have is termed a ‘White Chocolate Brownie’.




…But there IS white chocolate in this Peanut Butter Blondie recipe
Yes… I know! The observant will be questioning the addition of white chocolate to these gluten free blondies and asking whether they are actually white chocolate brownies. But the answer is still no. Although these Peanut Butter Blondies do have extra white chocolate chunks thrown into the mix, they are merely decadent add-ins. Not a fundamental part of the basic blondie recipe.
But whatever you think they should be called, one thing’s for sure. These peanut butter blondies are soft, slightly chocolate-sweet, caramelly, squidgy and very peanutty. Definitely worthy of a smile.

Other recipes you might like…
I am hoping to get some new gluten free blondies made soon, but in the meantime, we have a load of amazing brownie recipes on the blog. You can check out our dedicated Tray Bakes Index for inspiration. They are all amazing bakes. I think our favourites though, are the seriously grown-up Coffee Brownies, the somewhat more virtuous Beetroot Brownies and Pear & Walnut Brownies, the simple Perfectly Fudgy Gluten Free Brownies and the Chocolate-Orange Brownies (made with orange chocolate). But actually, why stop there? The Chocolate-Banana-Coconut Brownies are equally divine, as are the epic Toblerone Brownies and the fruity, gooey Chocolate-Cherry-Pecan Brownies. Decisions… decisions!
If it’s peanuts that make you happy, we love to celebrate these too at Gluten Free Alchemist. From really easy Peanut Butter Cookies and Peanut Butter Brownies, to light, sweet and crunchy Ful Sudani (Sudanese peanut macaroons). We also have Dark & chewy Chocolate-Peanut Butter Cookies on offer, some easy Peanut-Chocolate Chip Biscuits and also Chocolate Peanut Butter Oat Crumble Bars. We even have a Peanut Butter Chicken Curry!
