This delightful cake combines a moist almond-infused sponge with swirls of sweet berry jam and fresh blackberries. Finished with a crunchy flaked almond crumble, it's the ultimate treat for afternoon tea or a weekend gathering.
Preheat your oven to 180°C (160°C fan/gas 4). Grease a 20cm square cake tin with a little butter and line the base and sides with baking parchment.
In a large mixing bowl, cream together 200g of the butter and 200g of the golden caster sugar using an electric whisk until the mixture is pale, light, and fluffy.
Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Once the mixture is smooth, fold in 225g of the plain flour, the baking powder, ground almonds, milk, and your choice of vanilla or almond extract.
Transfer the batter into the prepared tin and level the surface with a spatula. Spoon small dots of jam over the top, then scatter the blackberries evenly, pressing them gently into the batter.
To make the crumble topping, combine the remaining 25g butter, 25g sugar, 50g flour, and a pinch of salt in a small bowl. Rub the ingredients together with your fingertips until they reach a crumbly consistency. Stir in the flaked almonds.
Scatter the crumble mixture over the cake, followed by the extra 1 tbsp of caster sugar. Bake for 45–50 minutes, or until a skewer inserted into the center comes out clean. If the cake needs more time, return it to the oven for another 5–10 minutes.
Allow the cake to cool in the tin for at least 20 minutes before removing, slicing, and serving.
To prevent the blackberries from sinking to the bottom, you can toss them in a teaspoon of flour before scattering them. If the crumble topping starts to brown too quickly, cover the tin loosely with foil for the final 10 minutes of baking.
