This Peach Crumble Cake is perfect for summer picnics. It's simple to make and super delicious with a hint of cinnamon and ginger.
Combine flour, baking powder, salt, cinnamon and ginger in a medium bowl. In another bowl or jug, combine milk and cream. Add flour mixture to the butter in thirds, alternating with milk, starting and ending with flour. Pour batter into the pan. Top with a layer of sliced peaches.
To make the crumble topping, combine the sugar, brown sugar, flour, cinnamon and butter. Rub butter into the mixture with your fingertips, and then add the pistachios and combine. Sprinkle evenly over the peaches.
Bake for 30-40 minutes until crumble is golden brown and a skewer inserted into the cake comes out clean. Cool in the baking tin for 10 minutes before cutting into slices.
