Step 1Preheat oven to 180°C (160°C fan) mark 4. Grease and line a 900g (2lb) loaf tin with baking parchment. Make the crumb topping: using your fingers, rub the butter into the flour until mixture resembles large breadcrumbs. Stir through sugar and pecans. Set aside.
Step 2To make the cake, in a large bowl mix the flour, sugar and baking powder. Gently mix in blueberries. In a jug mix milk, egg, oil, lemon zest and juice (it will curdle). Add to the dry ingredients and stir until just combined. Scrape into prepared tin and spread to level.
Step 3Sprinkle crumb topping over cake batter, squeezing it into larger clumps as you go. Bake for 1hr, or until a skewer inserted into the cake comes out clean. Allow to cool for 10min in tin, then transfer to a wire rack and serve just warm or at room temperature.
