Rosie Makes: Chocolate and Chestnut Brownies

Chocolate Chestnut Brownies

‘Chestnuts roasting on an open fire…’

It’s become something of a festive Rosie Makes tradition at this time of year to put a seasonal spin on everyone’s baking favourite – the brownie. Last year I experimented with peppermint (still a firm fave) and the year before was chocolate, pecan and cranberry. This year, I wanted to incorporate another favourite seasonal ingredient of mine – chestnuts. Last year I used the flavour pairing in a scrummy yule log, and I love the combination of rich chocolate and the sweet nuttiness of chestnuts. You’ll be glad to hear there’s no faffing with roasting and shelling; this recipe uses whole vacuum packed ones for ease. They are soaked in a sugar mixture beforehand, giving an almost caramel-y depth of flavour to the brownie. Delicious served warm from the oven with a scoop of vanilla ice cream as an advent-worthy dessert. To make them, you will need:

120g shelled cooked chestnuts (I used vacuum packed ones)
100g brown sugar
1 tsp vanilla extract
12 ml dark rum (optional)
50g plain flour
1 medium egg, separated
100g unsalted butter
100g chocolate, broken up (I used a mixture of milk and dark chocolate).

Preheat the oven to 170C/ Fan 150C/ Gas 3. Chop the cooked chestnuts and put them into a bowl with half the sugar, vanilla and rum (if using) and mix well. Fold in the flour.

In the bowl of a stand mixer, whisk the egg whites until soft peaks form. Add the rest of the sugar to make a soft meringue mixture.

Gently melt the chocolate and butter over a pan of simmering water.

Once the chocolate has almost melted, remove the bowl from the heat and allow the residual warmth to finish the job – or you risk splitting the chocolate. Combine the chocolate and chestnut mixture. .

Pour into a greased and lined brownie tin (or I used pyrex) and bake for 25 – 30 minutes until just set in the middle, so they are nice and gooey.
