I first saw this slice on Jane’s, (The Shady Baker) July 2015 In My Kitchen post. I was immediately smitten by the idea of it. In my view there is no better combination than chocolate, walnuts and rolled oats. It is a combination made in heaven. I commented that her slice looked and sounded wonderful and Jane generously emailed me the recipe.
I can assure you the slice did not disappoint. It is to die for. I mentioned to Maus last night that I don’t think I should make it again as it is so good, I can’t get it out of my mind and, subsequently, I am eating much more of it than my waistline would suggest is wise.
The base is firm and crunchy, the filling is soft and gooey and the icing is sweet and chocolaty: very good indeed.
I searched Jane’s blog for the recipe so I could link this post back to it but it appears Jane hasn’t posted it. As it is so yummy I decided the recipe must be shared. Jane mentioned that the recipe is from the 2015 Red Tractor Designs calendar.
Base
- ½ cup self-raising flour, sifted
- pinch salt
- 1 cup rolled oats
- ½ cup brown sugar
- 125g butter, melted
Filling
- 70g butter
- 70g dark chocolate, chopped
- ⅓ cup castor sugar
- 1 egg, beaten
- ⅓ cup self-raising flour, sifted
- ⅓ cup plain flour, sifted
- ⅓ cup milk
- 70g walnuts, finely chopped
- ½ tsp vanilla extract
Icing
- 15g butter
- 30g dark chocolate
- ⅓ cup icing sugar, sifted
- 1 tsp vanilla extract
- 2 x 20 ml tbs hot water
Base:
- Preheat your oven to 180°C.
- Line a slice/brownie tin with baking paper. My tin is 27.5cm x 17.5cm x 3.2cm and it was perfect so choose a tin about that size.
- Mix all the dry ingredients into a bowl.
- Melt the butter and then add it to the dry ingredients. Mix well.
- Press the dough into the prepared tin.
- Bake in preheated oven for 10 minutes.
Filling:
- Put the butter and chocolate into a mixing bowl and melt. I did this in my microwave but Jane suggested placing the bowl over hot water – either way would do.
- Add the sugar and beaten egg, mix well.
- Add the sifted flours, milk and vanilla, mix well.
- Stir in the walnuts.
- Spoon filling over hot base and bake for a further 20 minutes.
- Remove from oven. Cool before icing.
Icing:
- Melt butter and chocolate.
- Add sifted icing sugar, vanilla and hot water.
- Beat until smooth.
- Spread icing evenly over slice. Top with extra walnuts, if desired.

That icing/ganache looks so rich and delish. I’m always keen on anything with walnuts. Just polished off another one of your pumpkin cake loaves today. I love that recipe – so easy!
Looks delicious Glenda! xx
Thanks Taryn
And here I was just saying to Pete how I need to start losing my winter weight – oh well…
Have a wonderful week Glenda.
🙂 Mandy xo
Mandy, Did you give soap making a try?
Hi Glenda, Pete wasn’t home long enough when he was called away on another trip so his soap making has taken a little bit of a back seat sadly. Everything ready to rock and roll when he is home though. 🙂
Oh my Glenda it really does look so scrumptious… might have to try this recipe sometime. But at the moment trying to work off some clotted cream that seems to be hanging around the hip area 🙂
Oh! No! Moya!!! What can I say?
Love the sound of this flavour and texture combo. Can’t go wrong with walnuts and chocolate though in my opinion 🙂
Hi Leah, it is a deadly good combo.
Hmmm I have a big bag of walnuts plus the rest of the ingredients… I wonder if this will tempt the G.O. away from his usual biscuit fare 🙂
Hi Ella, if it doesn’t, there will be all the more for you and that can’t be bad.
Oh these look soooo good! Love the combo of walnuts and chocolate with the crunch oats base!
Hi Indira, we are of like minds.
Ooooh, how scrumptious! I LOVE walnuts in cakes and slices, especially with chocolate. Thanks for sharing the recipe xx PS not sure my waistline can cope either! 😉
Hi Liz The bloody waistline always gets in the way doesn’t it?
Just what I need. Scored a big bag of walnuts the other day. Looks perfect.
Hi Francesca, it really is a great recipe. I followed it exactly and it turned out perfect.
That’s great news Glenda and now, I am about to do your/Shady’s walnut slice.
Let me know what you think.
You hooked me with that first photo. Thanks for posting the recipe because it sounds like a winner.
It sure is Diane.
I saw this and thought it looked mighty good but lacked your tenacity in locating the recipe! This looks perfect for the weather we have at the moment.
Anne, it is a great recipe. Jane sold me with her wonderful photo and description of it. She was not wrong.
