If you hadn’t guessed already, I love creating easy, delicious treats for my family. I don’t do anything fancy, complicated or time consuming, and I also don’t use premium ingredients! For me and my baking, I really don’t think top of the range butter, flour or sugar are necessary, or make a difference to the flavour. This makes baking really quite cheap, and, I think, far better for you than shop-bought treats with additives, preservatives and flavourings. I’ve always liked the fact that I know exactly what’s gone into my bakes – and therefore what I’m feeding my family – and I can always cut the sugar if I think it’s a little sweet.

This week’s bake is a fun marble traybake. It’s a great family bake, and super moreish! As soon as it comes out of the oven I press mini marshmallows all over the top. They melt slightly and add a bit of squishy fun. As I said to my sister, “It doesn’t matter what it looks like, as long as it tastes good.” A good rule to bake by, I would say!

Marshmallow Marble Traybake

Use an 8 or 9 inch square pan, lined with baking paper or silicone sheets


200g self raising flour
200g baking spread or butter
200g caster sugar
4 eggs
1.5 tsp vanilla extract
1tsp baking powder
20g cocoa powder
1 tbsp milk
100g chocolate chunks
100g mini marshmallows


  1. Preheat your oven to 200°C/180°C fan/gas mark 6 and line your brownie pan.
  2. Pop all the ingredients into a bowl except the cocoa and chocolate chunks.
  3. Mix it up!
  4. Add the chocolate chunks and combine.
  5. Split the mixture into two bowls.
  6. Add your cocoa to one of the mixes and combine. Add the milk if it’s a bit stiff.
  7. Alternately pop large spoonfuls of the vanilla and chocolate mixture into the pan, keeping them quite close together, until you run out of batter! I use my trusty ice cream scoop – six scoops of each seems to be about right. Oh, and don’t worry about using the scoop in both mixes at once – it’s going to be a marble cake, so you’re just helping the process!
  8. Grab a skewer or the handle of a spoon and drag it through the mixture. This swirls it together a bit and mixes the two flavours. Don’t swirl too much though!
  9. Bake for 30-35 minutes until springy.
  10. Take out of the oven, scatter and press on your mini marshmallows if you’re using them.
  11. Leave to cool and cut into squares.
