The Ingredients
You will need these ingredients to make your vegan blondie.
A couple of notes regarding the ingredients
Flaxseed: you will need to use ground flaxseed. You can find it in all the bigger supermarkets and most health stores. If you can’t access it, simply opt for whole flaxseed and use a blender or food processor to blend it until powdery.
Vanilla extract: I used vanilla extract in liquid form (not paste or powder).
Cornstarch: Sometimes known as cornflour.
White vegan chocolate: Ideally, you will use white chocolate. However, no worries if you can’t find it. Simply substitute for other vegan chocolate of choice (such as vegan 'milk' chocolate or dark chocolate).
Nuts: I used hazelnuts as they make the perfect flavour addition. Feel free to substitute for another nut of your choice (I would recommend pecans or almonds).

Expert Tips
1. Do not overmix
The key to perfect vegan blondies is the batter. My friendly tip is NOT to overmix it.
The more you mix it, the more your blondie will resemble a cake. That's definitely not what we're aiming for!
2. Don’t Overbake
It’s important you don’t over bake these. It will dry them out and change their texture, making them resemble a cake rather than a blondie.
To check they’re baked, just gently shake the tin. If the batter stays in place or wobbles just in the middle, they’re done.
If it wobbles everywhere, put them back in the oven for 3-5 minutes and then check again.
Remember that the blondies continue to bake even after you’ve removed them from the oven (especially the centre). With this in mind, you should remove them from the oven when the edges are golden brown, whilst the middle still looks gooey and underdone.
3. Don't poke with a skewer
Have you ever baked a cake? Then you will know the trick with a wooden skewer. To test if a cake is done, a wooden skewer should be inserted in the middle. If it comes out clean, the cake is done.
However, it's really important you don't do the same when baking blondies. They are meant to be gooey, so a skewer shouldn't come out clean at all. If you wait until the skewer comes out clean, your blondie will be very overbaked.
4. Slice when it’s cold
I know the feeling so well. You’re so excited about what you've just baked and want to slice it and try it immediately. Whoops - massive mistake here!
You should never cut baked goods whilst they’re still warm. Let the blondie cool down completely and then slice it.
When blondies are still warm, they will be more gooey and messy. This will make it impossible to get those sharp edges we all love and adore.
FAQ + Troubleshooting
The most common reason for dry blondies is over-baking. If your blondies are dry in the middle they've been baking for too long.
If this is the case, there is not much you can do about it except removing them sooner when you bake them the next time. Still, I encourage you to use the 'dry' batch in order to minimise food waste. I've got some good suggestions for you below.
To make dry blondies taste less dry you can do the following. First, you can use a bit of heat. Wrap them in a towel and microwave on medium heat for about 10 seconds.
Secondly, you could top them with some delicious ice cream. This works very well in countering the dryness.
Alternatively, you could top them with various liquid sweeteners (such as chocolate sauce, maple syrup) or whipped cream. Find more tips here.
I used a tin that measures 8x6 in (21x16cm). This yielded 9 portions.
First, let them cool completely, then cut into squares and store in an airtight container. Do NOT refrigerate as this can dry them out.
Yes, absolutely. Again, you will need to let them cool down and then cut them into squares. Place in a freezer-proof container and store for up to 1 month.
To make sure they don’t stick to each other in the freezer, place a small sheet of baking paper between each slice.

Easy Vegan Blondie
Equipment
- Measuring cups or scales
- Baking tin (8x6 in, 21x16cm)
Ingredients
- 1,5 tablespoon ground flaxseed
- 3 tablespoon boiling hot water
- 100 g light brown sugar
- 50 g white sugar
- 145 g plain white flour
- A pinch of salt
- 2 teaspoon cornstarch
- 100 g dairy-free butter
- 1,5 teaspoon vanilla extract
- 70 g hazelnuts
- 30 g vegan white chocolate
- 20 g vegan white chocolate optional drizzle
Instructions
- Boil a kettle. In a small bowl, mix flaxseed with boiling hot water and set aside. This will create a flaxseed 'egg'.
- In a separate bowl mix together both sugars, flour, salt and cornstarch.
- Melt butter (either in a microwave or in a small pan - careful not to burn). Add vanilla extract and stir well.
- Then add the flaxseed 'egg' to the butter mixture. Stir well.
- Slowly pour your wet mixture over your dry ingredients. Mix until combined and no more flour specks can be seen.
- Chop up the hazelnuts. Roast hazelnuts in a small non-stick pan until golden around the edges (2-3 minutes). Do not use any oil.
- Chop up white chocolate.
- Add hazelnuts and white chocolate to your batter. Gently fold them in, making sure not to overmix the batter.
- Pour the mixture into a lined baking tray.
- Bake at 180°C/356°F for 25-20 minutes (fan oven setting*).
- Melt white chocolate (in a microwave or over a water bath) and drizzle over the blondie in quick diagonal motions.
- Allow to cool before slicing.
Notes
- *Not using a fan oven setting? Bake at 200°C/392°F.
- Set the flaxseed egg aside for long enough. You will want it to get an almost jelly-like consistency.
- Be careful not to overmix your batter.
- Don't have baking paper? Use dairy-free butter to grease all the inner sides of your tin well before baking.
- To check the blondies are baked, just gently shake the tin. If the batter stays in place or wobbles just in the middle, they’re done. If not, place back in the oven and try again in 5 mins.
- To freeze: Place in a freezer-proof container and store in a freezer for up to 1 month.
