This cake is bursting with fresh strawberry flavour, from the soft and fluffy sponge, to the irresistible strawberry frosting and the strawberry crunch topping!
Line a rectangular cake tin (9 x 13 inches) with baking paper, letting the edges hang over the top edge.
Measure the flour, sugar, baking powder and bicarbonate of soda into a mixing bowl. Stir to combine.
Add the eggs, butter, yogurt and vanilla bean paste to the bowl, and beat it all together until the batter is smooth, scraping the bowl halfway through.
Transfer the batter into the prepared pan and level.
Bake for 35 minutes or until the cake is springy to the touch and a skewer inserted in the centre comes out clean.
Lift the cake out of the pan and cool on a wire rack before frosting.
Make the frosting
Beat all the ingredients together until the frosting holds peaks. Add more strawberry powder to taste. Swirl the frosting over the cake.
Decorate the cake
Crush the biscuits in a food processor or in a mortar and pestle, and mix with the freeze-dried powder. Sprinkle over the frosted cake.
Decorate with fresh sliced strawberries and edible flowers just before serving.
