Coffee Hazelnut Cake with Mascarpone Icing

Intense, rich, drag-me-out-of-bed coffee; yep, it’s the lonely hero of many a dark January morning, and for me, my second favourite cake flavour (after chocolate…duh). If you too trust in the caffeine hit, are partial to a slab of cake and have fallen off the health wagon you should definitely try out this recipe- the loaf format looks a bit different and the hazelnuts pair really well with the strong coffee flavour which is delivered in the sponge, frosting and espresso drizzle.

Method:

  1.  Preheat the oven to 160c and grease/line a large loaf tin.
  2. Cream together the butter and sugar using an electric whisk (or in the bowl of a stand mixer using the paddle attachment) until light and fluffy.
  3. Add the eggs in one at a time, whisking well in between each addition to ensure they are well incorporated (you can add a little of the flour if you’re worried about curdling).
  4. Once the eggs have been added sift in the flour, salt and baking powder. Fold into the mix then add the instant coffee and stir. Scrape the batter into the loaf tin and bake for 30-35 minutes (or until golden brown and cooked all the way through- a skewer should come out clean with a few crumbs attached when inserted).
  5. Allow the cake to cool in the tin while you make the frosting and soak.
  6. For the frosting, place the butter, mascarpone and instant coffee in a bowl (or again, use a stand mixer) and whisk until light, well combined and fluffy. Now gradually add the icing sugar whilst mixing on a slow speed. Once all the icing sugar has been added increase the speed and keep whisking until you have a spreadable, light and smooth icing. Set aside.
  7. For the soak simply mix together the coffee and sugar. Take your cooling loaf cake and slice in half horizontally. Prick holes in the surface of each piece and drizzle the soak all over, allow it to sink in. Set aside until completely cool.
  8. Once the cake is completely cool spread a generous amount of mascarpone icing across the bottom layer along with a sprinkling of hazelnuts. Sandwich on the top sponge and cover the outside edges in the remaining icing. If you like, you can use a flat piping nozzle to create a ripple look, then top with more hazelnuts and some espresso powder.

Enjoy!
