Description
This vibrant upside-down cake features a luxurious layer of caramelized wild blackberries resting beneath a light, buttery sponge. By utilizing a rapid food-processor method, this recipe achieves a perfect structural balance between juicy fruit and a tender, velvet crumb.
Ingredients
- 250g fresh wild blackberries
- 100g plain flour
- 100g caster sugar
- 100g unsalted butter, softened
- 50g light brown sugar
- 2 large eggs
- 1 tsp baking powder
- 0.5 tsp bicarbonate of soda
- 2 tbsp full-fat milk
- 1 tsp vanilla extract
Instructions
- Prepare the oven. Preheat your oven to 180°C (350°F) and grease a 24cm by 5cm ovenproof dish thoroughly.
- Create the base. Sprinkle the light brown sugar evenly over the greased bottom of the dish to form a sandy base.
- Dry the fruit. Wash the blackberries gently and pat them completely dry on paper towels to ensure a clean flip.
- Arrange the berries. Scatter the blackberries in a single, dense layer over the brown sugar and press them down lightly.
- Sift dry ingredients. Place a fine-mesh sieve over a food processor and sift together the flour, baking powder, and bicarbonate of soda.
- Blitz the batter. Add the softened butter, eggs, caster sugar, vanilla, and milk, processing until the mixture is smooth and satiny.
- Spread the batter. Dollop the batter over the blackberries and spread carefully into a thin, even layer.
- Bake the cake. Bake for 25 minutes until golden brown, testing the center with a skewer until it emerges clean.
- Cool and flip. Rest the cake for 10 minutes, loosen the edges with a knife, and invert onto a serving plate with a swift motion.
- Final cooling. Allow the cake to sit for at least 30 minutes before slicing to ensure the sponge is set and the caramel is absorbed.
Notes
- Use a glass or ceramic baking dish for better heat management compared to dark metal pans.
- Ensure the butter is soft to the touch to achieve a perfect emulsion during the quick blitz process.
- Double-check that blackberries are completely moisture-free to prevent the base from turning into a soggy puddle.
- Let the cake rest in the pan for exactly ten minutes to allow the caramel to thicken before flipping.
