🍪 What is Biscoff?

Biscoff is a small crunchy cookie created by Lotus with a unique, slightly caramel, flavor. It's perfect with a cup of coffee!

Lotus have created a Biscoff cookie butter (also called Biscoff spread) as well as other variations of the classic Biscoff cookie, such as sandwich cookies and ice cream.

✏️ Making a tasty and easy recipe

The concept of chewy Biscoff blondies isn’t new. However, I was super keen to create an easy Biscoff blondie with a twist. I’m obsessed with the creamy sweetness of white chocolate, so adding this to the caramelised flavor of Biscoff biscuits was a perfect combination for me.

These tasty traybake bars of joy are basically white chocolate Biscoff brownies filled with Biscoff cookie butter!

I love having both the soft gooeyness of a white chocolate blondie combined with a crunchy Biscoff cookie butter stuffed centre.

🥘 Ingredients notes

• Always sieve your flour, confectioners sugar and baking powder. I used to be a bit lazy and skip this part, but it really makes such a difference to get you smooth, lump-free mixtures.

• Using high-quality ingredients will make a huge difference in the taste of your Biscoff blondies. I’ve used different brands of white chocolate and you can really tell the difference between a cheap brand and high-quality baking chocolate. I use Callebaut Belgian white chocolate for this recipe (both as chips and melted) and it’s delicious!

• I'd always recommend using vanilla extract over vanilla essence where possible, as it has a much purer vanilla flavor.

• When measuring your ingredients, I always recommend using weights rather than cups where possible for greater accuracy. Accuracy is especially important for the amount of flour used in your cake.

🔪 Equipment notes

I like to use digital scales for weighing my ingredients as it's easier and more accurate than other scales. I'm a fan of these KitchenAid or Salter ones!

Use measuring spoons for your teaspoon and tablespoon amounts where possible. Be sure to level off the heaped ingredients in your scoops before adding them to your mix.

🍱 Storage

I usually keep my Biscoff blondies in an airtight container in the fridge (as I like the cold fudgy texture). Your blondie bars should keep for up to a week in the fridge or a few days at room temperature.

You can freeze your Biscoff blondies by wrapping them in clingfilm / plastic food wrap and then a layer of foil. They should keep for up to a few months frozen. Defrost and enjoy!

💭 Top tips for success

• To help prevent your chocolate chips from sinking to the bottom of your Biscoff blondie bars, you can first toss them in the flour before they're added to the blondie mixture.

• I usually crush my Biscoff biscuits by putting them into a sandwich/freezer bag and sealing it, then smashing it with a rolling pin. You can also whizz them up in a food processor or blender instead. I like to leave these biscuits to have some large chunks in them for an extra crunch as you bite into your blondie bars.

• When your Biscoff blondies come out of the oven, they’ll be quite soft, but don’t panic! These white chocolate blondies will firm up as they cool to give that fudgy chewy goodness.

• If your white chocolate Biscoff blondies aren't firm enough for your liking once they've cooled, you can refrigerate them. There's something about having a chilled blondie that adds an extra bit of sweet mouth joy for me.

♻️ Alternatives and substitutions

Depending on how much crunch you want to your Biscoff blondie bars, you can crush your Biscoff biscuits for the middle layer to the point of fine crumbs or larger chunks. I usually go for little chunks so you can get that noticeable crunch with every bite, but that’s my personal preference.

For decoration, I usually press whole Biscoff cookies into the top of the blondie before baking, but this is optional. You can swap this for large pieces of the biscuits or omit them altogether.

I like to drizzle warmed Biscoff cookie butter over the top of the blondie bar traybake before cutting into squares. This is also optional! If you'd like to do this, I recommend using a piping bag and a small round piping tip (like the ones in this writing piping tips set) for neat lines. However, you can also use a plastic sandwich bag (freezer bag) with the corner cut off.

If you like your gooey blondies a little less sweet, then I’d recommend omitting the white chocolate chips. There will still be plenty of creamy white chocolate in the blondie mix itself so you won’t lose out on this creamy white chocolate flavor to your Biscoff blondies.

This recipe calls for Biscoff cookie butter spread, but there is currently a smooth (creamy) or crunchy variety on sale. I usually use the smooth Biscoff spread, so I can also use it to drizzle over the top. However, the crunchy one would also be delicious for the inside Biscoff layer.

Gluten-free option:

To make these Biscoff blondies gluten-free, swap the plain / all-purpose flour for a gluten-free plain flour blend of the same quantity.

I usually recommend a pre-mixed blend such as King Arthur's measure for measure flour or Freee from Doves Farm.
