Gluten-free chestnut and chocolate brownies

Ingredients:

Roasted Chestnuts

500g fresh chestnuts

Brownie

350g cooked and peeled chestnuts
200g good quality dark chocolate, broken into squares
200g unsalted butter, chopped
1 ¼ cups brown sugar
1 tsp vanilla extract
4 eggs, lightly beaten
1/2 cup gluten-free self-raising flour
2 tbsp cocoa
Pinch salt

Method:

Roasted Chestnuts

Preheat oven to 200°C (180°C fan-forced)
Cut a shallow cross into the flat side of each chestnut shell. Place prepared chestnuts onto a baking tray and bake for 15 to 20 minutes or until the shells split open
Once cooked, remove chestnuts from the heat and wrap in a clean tea towel for 5 minutes. While chestnuts are still warm, quickly peel off the outer brown shell and remove the papery thin skin underneath

Tips & Hints:

Makes 350g cooked and peeled chestnuts as required for brownie recipe

Brownie

Reduce oven to 180˚C or 160˚C fan-forced. Grease and line a 16cm x 26cm x 2-3cm deep slab pan with baking paper, leaving a 2cm overhang on the sides of the pan
Set aside 50g cooked and peeled chestnuts. Place remaining chestnuts into a food processor. Process until fine crumbs form (you’ll need 2 cups ground chestnuts). Set aside
Place chocolate and butter in a large microwave safe bowl and microwave on high for 2 minutes, stirring with a metal spoon every minute until melted. Set aside to cool
Using a metal spoon, stir in sugar, vanilla and eggs into chocolate mixture until well combined. Sift over flour, cocoa and salt. Stir to combine. Gently fold through chestnuts. Pour into prepared pan. Chop reserved chestnuts and sprinkle over mixture. Bake for 25-30 minutes until a skewer inserted comes out with moist crumbs sticking. Cool completely in the pan. Cut into squares. Serve with whipped cream and a dusting of cocoa if liked
