This recipe makes a mini raspberry swirl marble loaf cake. It includes a vanilla cake mixed with a raspberry batter so you get two flavours in one cake. The cake is soft and moist with a fluffy texture and goes perfectly with an afternoon cup of tea.

This raspberry cake is baked in a 1lb loaf tin which is perfect for baking small loafs. This cake is ideal for times when you fancy some cake but don’t want lots of leftovers. I love this cake as its the perfect recipe to use up any raspberries you have that are going soft.
The cake is made with a mixture of vanilla and raspberry batter that go great together. The raspberry batter is made using a homemade raspberry jam that I make with fresh raspberries and the vanilla batter is simply flavoured with vanilla extract. Another thing I love about this cake is that you get to enjoy two delicious flavours in one cake.

How to Make Raspberry Swirl Marble Loaf Cake
Make the raspberry jam
Add the raspberries, sugar and lemon juice to a saucepan and place on a medium to high heat. Stir continuously until the raspberry sauce thicken. It will turn into a thick syrup and go a deep red when ready. Set aside to cool which will thicken it further.
Preheat the oven and line tin
Preheat the oven to 160oC and line a small 1lb loaf tin with parchment paper then set aside.
Make the vanilla batter
In a mixing bowl, combine the butter, oil and sugar. Mix in the vanilla, egg, yoghurt and milk. Mix in the salt and bicarbonate soda then fold in the self-raising flour.
Remove some batter and add the jam to it
Transfer ⅓ of the batter to another bowl then add the raspberry jam to it and combine well. Optionally, you can add a few drops of pink food colouring to brighten the batter further.
Transfer the batter to the loaf tin
Add ¼ cup of the vanilla batter to the loaf tin then add ¼ cup of the raspberry batter. Place the batter in random sections of the tin to create a marble effect. Repeat the process until all the batter is used up then use a skewer to mix the batter in a circular motion to make the swirls.
Bake
Bake the cake in the oven for 55 – 60 minutes. Once baked, place the cake in the tin on a cooling rack to cool for 1 - 2 hours. Once cooled, slice and serve.
