💭 What is a fridge cake?
A fridge cake is a no-bake traybake, which is chilled to set and not baked at all.
It is usually cut into cookie bars, fingers or bites, depending on what size of a treat you want.
A brownie pan (mine is 20 cm x 20 cm, approximately 8 inches x 8 inches) is a good-sized cake tin to use for no-bake treats.
👩🏻🍳 Make your own oat flour
These Biscoff chocolate bars are made with homemade oat flour.
But don't worry, it's super easy to make at home.
I used porridge oats to make these fridge bars, which are also known as rolled oats, but you could also use oatmeal or jumbo oats.
It doesn't matter how coarse or fine your oats are as you will be blending them.
Use a blender, food processor or spice mill to grind the oats into a coarse flour.
Just blitz it a few times, it doesn't take long.
📋 What you need to make Biscoff oatmeal bars
Here are the simple ingredients you need to make these delicious Lotus Biscoff biscuit bars.
- Oats - porridge oats, rolled oats or otameal
- Biscoff spread - a cookie butter
- Maple syrup - to sweeten
- Vegan butter - or spread
- Salt - just a pinch
- Dark chocolate - or dark chocolate chips
See the printable recipe card below for full ingredients, method and calories.
🧾 Variations to the recipe
Here are a few easy substitutions to make these Biscoff candy bars.
- Golden Syrup- you could use golden syrup instead of maple syrup.
- White Chocolate - you could melt vegan white chocolate to use instead of dark chocolate or use it as a drizzle on top of the set dark chocolate.
- Raisins - can be added to the oat and Biscoff mixture for a chewy finish.
- Cranberries - are also a good addition, especially if you are making these vegan oat bars as a Christmas gift.

In 1932 a Belgium baker called Jan Boone created biscuits with a delicious caramel flavour. He called these Lotus Biscoff and delivered them to restaurants and cafes to be enjoyed with coffee.
People began to crumble these biscuits on bread or toast and some would dunk it in their coffee first to soften it, so Lotus Biscoff bakeries decided to make it into a spread.
This distinctive caramel spread (cookie butter) is still made in the same village (the village of Lembeke in Kaprijke, Belgium), where the Biscoff biscuits were created in the 1930s. They are both still made in the family-run bakeries there.
Yes, Lotus Biscoff spread is one of those products that are accidentally vegan.
It's a combination of the words biscuit and coffee, as it was created as a biscuit (cookie) to be served with coffee.
Lotus Biscoff can be called Lotus, Biscoff or speculoos. Speculoos is the generic name for this type of biscuit (cookie) in Holland.

🍪 Are these Biscoff cookie bars easy to make?
Yes, these chewy oaty bars are super easy to make.
A quick whizz of the oats to make flour, before the melted Biscoff mixture is stirred in and pressed into a lined tin, then chilled before the melted chocolate topping is added.
It takes just a few minutes to make the base and this vegan Biscoff traybake is super easy to make.
💭 Top tip
For easy removal and cutting, make sure you line your brownie tin.
If you lightly butter the tin first, then add a strip of non-stick baking paper across the tin, the vegan oat bars will be easy to lift out and then cut.
🔪 Cutting tip
I cut this vegan Biscoff cake into 9 bars, but after taking photos I decided the bars were just too big.
So, I cut each of the bars in half, so they were more fingers of Biscoff cookie bars.
I have included calories in the notes of the recipe card for 9 large bars or 18 more treat-sized snacks.
🌡️ Storing oat bars
These nut-free oat bars can be stored in an airtight container in the fridge.
They will keep for up to a week but are unlikely to last that long as they are so good.
You can also freeze them, then defrost them in the fridge overnight for lunch boxes or an afternoon snack.

Instructions
- Grease and line a brownie tin or other deep tray (20c x 20 cm or 8 inch x 8 inch approx).

- To melt chocolate in a bain marie, break and pop in a bowl that will sit over a pan of simmering water. The bottom of the bowl must not touch the water or the chocolate could seize.

Mine turned out so crumbly and I don’t know what I’ve done wrong. They still taste good but they fall to bits.
Jacqueline Meldrum
It sounds like it wasn't pressed enough. You really need to mix it well then press, press, press. It' stops it being crumbly. I am making some tonight to take to work tomorrow. I hope you try it again.
