Instructions

Preheat and prepare the pan – Preheat your oven to 355°F (180°C) with the fan on. Grease a 9 x 5-inch (23 cm x 13 cm) loaf pan with room-temperature butter. Cut a piece of parchment paper to fit the bottom of the pan, ensuring the paper hangs over the sides. This will help lift the cake out after baking. Grease the parchment paper as well, making sure it’s well-coated with butter.
Prepare the batter – In a mixing bowl, combine the sugar and melted butter. Use a whisk or mixer to blend them together for about 2 minutes, until smooth and fully combined. Add the Dutch-process cocoa powder, almond flour, baking powder, espresso powder, vanilla extract, and salt. Mix everything together for about 1 minute until fully combined.
Combine wet ingredients – Crack the eggs into the bowl with the batter and mix until fully incorporated. Then, add the milk and continue mixing until the batter is smooth and well combined.
Add the flour – Sift the flour into the batter to prevent lumps. If using an electric mixer, set the speed to low and mix gently until smooth and lump-free. Be careful not to over-mix, as this can make the cake dense instead of light and airy.
Bake and cool the cake – Pour the batter into the prepared loaf pan and bake for 35-40 minutes, or until the cake has risen and has a crack down the center. To test for doneness, insert a toothpick—if it comes out with moist crumbs, the cake is done. Allow the cake to cool in the pan for 10 minutes, then transfer it to a rack to cool completely. For quicker cooling, place the cake in the refrigerator for 30 minutes.
Prepare the Rocher glaze – In a saucepan, melt the chopped dark chocolate and sunflower oil over very low heat, stirring until smooth and glossy. Remove from heat and stir in the diced almonds. Let the glaze cool for 20 minutes, stirring occasionally to speed up the process.
Glaze the cake – Ensure the cake is completely cooled before glazing; otherwise, the glaze won’t stick. Place a parchment-lined tray under the cooling rack to catch any drips. Pour the glaze over the cake, spreading it evenly. Scrape up any drips and spread them back onto the cake. Then, place the cake in the fridge for 30 minutes to allow the glaze to harden. Enjoy!

Notes

Weigh your ingredients – While I’ve included volume measurements (cups and spoons), use metric gram measurements if possible. A digital kitchen scale is more accurate than cups, ensuring precise, consistent results. Since weight is exact and volume can vary, a scale eliminates inconsistencies and will invariably give better results.

Choose the right mixing tool – You can use a whisk, or a hand or stand mixer for this recipe. Each option works well, but a mixer will save time and effort while ensuring a smooth batter.

Mix with care to avoid overmixing – When adding the flour, use low speed if using an electric mixer, and be careful not to overmix. As soon as the batter is smooth and well combined, stop mixing to preserve the cake's texture. Overmixing can lead to a dense cake.

Glaze at the perfect temperature – The ideal temperature for pouring the chocolate glaze is 95°F (35°C). It should feel like body temperature when touched—just right for a smooth, even coating.

Cool completely before glazing – Make sure the cake is completely cooled before pouring the chocolate almond glaze. If the cake is still warm, the glaze won’t adhere properly and could result in a messy finish. Patience is key!
