What Is Biscoff?

Biscoff is a type of cookie butter with the same consistency as peanut butter, but made from crushed Lotus ‘speculoos’ cookies, sugar, and a little canola oil. The resulting flavor is similar to graham crackers but sweeter and more ‘buttery’, with hints of cinnamon and other warming spices.

It’s also really easy to find in most grocery stores near the peanut butter. This time, I’ve used this moreish cookie butter to make a decadent Biscoff blondie recipe.

Not only does removing the eggs and dairy not make these easy blondies any less decadent, but the recipe requires just 9 base ingredients (most are likely in your pantry now), a couple of bowls, and a mixer or whisk.

If your friends and family are anything like mine, these Lotus blondies will soon become one of your most highly requested treats, so I highly recommend making a double batch to freeze the leftovers for later!

The Ingredients

ingredients for Biscoff Blondies measured out against a white surface
  • Flour: I used all-purpose flour, though white whole-wheat flour works too.
  • Vegan butter: Use your favorite dairy-free butter, like Miyoko’s or Earth Balance. It needs to be at room temperature/softened.
  • Sugar: Brown sugar (not dark) provides these cookie butter blondies with extra moisture, chewiness, and a delicious caramel/butterscotch flavor.
  • Leavening agents: Combining baking powder and baking soda will provide lift and the correct texture to these eggless blondies.
  • Vanilla extract: Use natural, pure vanilla for the best flavor.
  • Salt: To balance and enhance sweetness and flavor in these sweet Lotus Biscoff blondies. Use sea salt/kosher salt rather than regular table salt.
  • Cinnamon: This pairs wonderfully with the spices present in Biscoff biscuits.
  • Flax eggs: A combination of ground flaxseeds and water will thicken into a great vegan egg substitute for these eggless blondies.
  • Lotus Biscoff: You can specifically use Lotus Biscoff cookie butter or rely on an alternative brand of cookie butter, which most major supermarkets now sell (including Trader Joe’s). Use smooth or crunchy. I also used separate whole Lotus biscuits to press into the top of the blondies.
  • Dairy-free chocolate chunks: (optional) Vegan white chocolate pairs particularly well with Biscoff, but dark chocolate will work, too.

What Else Could I Add?

  • Caramel sauce: Drizzled over the top.
  • Biscoff stuffed blondies: Spread an 8×8 inch square of biscoff across a piece of parchment paper and leave it to freeze. When adding the batter to the pan, only add half, then the frozen layer of biscoff, then the remaining batter.
  • Vegan biscoff buttercream: Pipe a swirl on the top of each brownie and top with a Biscoff cookie (whole or half).
  • Nuts: Add some chopped nuts (walnuts, hazelnuts, etc.) instead or along with the vegan chocolate chunks.

How to Make Biscoff Blondies?

  • 1) First, preheat the oven to 325F/165C and line a 9-inch square baking pan with parchment paper (with overhang). Then, mix the ground flaxseed and water in a small bowl, and set aside for 5 minutes to thicken.
  • 2) Next, use an electric mixer/whisk (or stand mixer) to cream the vegan butter and sugar in a large bowl until light and fluffy.
  • 3) Add the flax eggs and beat on high for 3 minutes. Then add the Biscoff cookie butter and vanilla extract and beat for a further minute.
  • 4) In a separate bowl, sift in the flour, baking powder, baking soda, cinnamon, and salt, and mix. Then, add ¼ cup at a time to the vegan butter mixture until it’s combined.

Be careful not to over-mix the batter, as the gluten in the flour can cause the blondies to become tough and dense.

  • 5) Fold in the vegan chocolate chunks with a spoon before pouring the dough into the prepared pan and leveling it using a layer of parchment paper and flat ingredients like a small saucepan or the bottom of a flat glass. If using, also press the Biscoff cookies into the top of the batter in a random placement.
  • 6) Transfer the pan to the oven and bake for about 35 minutes, until the blondies are crisp on the edges, with a slightly soft-looking center (they’ll continue to bake from residual heat as they cool outside the oven).

  • 7) Finally, allow the Biscoff blondies to cool completely in the pan before removing and slicing them. Enjoy!

You can cut the blondies into 12 pieces, 16 pieces, or even 24, depending on whether you want full-sized blondies or blondie bites.

FAQs

Can I use a whisk?

Absolutely. It’ll take a little more arm work than using an electric mixer, but it will work.

Why are my blondies cakey?

Usually, this is down to them being overbaked or if you’ve made an ingredient swap in the recipe.

Pro Recipe Notes

  • Measure the flour correctly: Fluff it up with a fork in its bag, use a spoon to transfer it to the measuring cup, then the back of a knife to level the top. This ensures you don’t add too much and have dry, dense Biscoff blondies.
  • Don’t over-mix the batter: If you overwork the gluten flour, the blondies may sink in the middle and become tough.
  • Be careful not to overbake: Otherwise, the blondies become dry rather than ‘buttery’, chewy, and tender. However, you can also slightly adjust the baking time on whether you prefer gooey, slightly tender, or firmer biscoff blondies.
  • Leave them to cool completely: They may fall apart if you attempt to slice them too soon.
  • To cut neatly: Leave the blondies to cool, then use a sharp knife, wiping it clean between each slice.

How to Store?

At room temperature: Cover the Biscoff blondies on the countertop for 2-3 days or store them in an airtight container in the refrigerator for 5-7 days.

In the freezer: Spread the sliced blondies across a baking tray to flash freeze until solid, then transfer them to a freezer-safe bag/container for up to 3 months. Leave them to thaw in the fridge overnight or at room temperature for several hours.

We love to microwave the blondies for 10-15 seconds before serving for a truly decadent treat, optionally with a scoop of vegan vanilla ice cream or some dairy-free cream.

    Everything gets better with Biscoff. I love the warm flavor combined with the blondie. That was really delicious and rich.
