Ingredients
- Almond flour (120g / 1 cup)
- Powdered sugar (120g / 1 cup) for sponge
- Egg whites (4 large), room temperature, whipped to soft peaks
- Whole eggs (4 large), room temperature
- All-purpose flour (40g / 1/3 cup) – can substitute with gluten-free blend
- Unsalted butter (60g / 4 tbsp) melted and cooled for sponge
- Strong brewed espresso or coffee (120ml / 1/2 cup) for syrup
- Granulated sugar (60g / 1/4 cup) for syrup
- Unsalted butter (225g / 1 cup) softened for buttercream
- Powdered sugar (150g / 1 1/4 cups) sifted for buttercream
- Espresso powder (1 tbsp) dissolved in 1 tbsp hot water
- Vanilla extract (1 tsp)
- Bittersweet or dark chocolate (150g / 5 oz) for glaze
- Heavy cream (120ml / 1/2 cup) for glaze
- Unsalted butter (30g / 2 tbsp) for glaze
Instructions
- Preheat oven to 425°F (220°C). Line a 9×13 inch (23×33 cm) baking sheet with parchment paper.
- Sift together almond flour, powdered sugar, and all-purpose flour in a bowl.
- Whisk whole eggs in another large bowl until pale and slightly thickened. Gently fold dry ingredients into eggs until combined.
- Whip egg whites in a clean bowl until soft peaks form. Gradually fold egg whites into almond mixture carefully to avoid deflating.
- Fold in melted butter until smooth. Spread batter evenly on prepared baking sheet.
- Bake for 5-7 minutes until sponge is lightly golden but not browned. Cool on wire rack, then trim edges and cut into three equal rectangles (approx. 9×4.5 inches).
- Make coffee syrup by combining brewed espresso and sugar in a small saucepan. Heat until sugar dissolves. Set aside to cool.
- Prepare espresso buttercream by beating softened butter until creamy. Gradually add powdered sugar and beat until fluffy.
- Dissolve espresso powder in hot water, add vanilla extract, then mix into buttercream. Adjust coffee intensity to taste.
- Assemble cake by placing one sponge layer on serving platter. Brush generously with coffee syrup (3-4 tbsp). Spread about one-third of buttercream evenly over sponge.
- Repeat with second sponge layer, syrup, and buttercream. Top with last sponge layer, brush with syrup but do not add buttercream on top.
- Make chocolate glaze by heating heavy cream in a small saucepan until just simmering. Pour over chopped chocolate and let sit 2 minutes, then stir gently until smooth. Stir in butter for shine.
- Pour glaze evenly over cake and smooth quickly with offset spatula before it sets.
- Refrigerate cake for at least 2 hours before slicing. Use a hot knife (dip in hot water and dry) for clean cuts.
Notes
[‘Whip egg whites to soft peaks to keep sponge light but stable; avoid over-whipping.’, ‘Use gentle folding motions to preserve air in batter for fluffier layers.’, ‘If buttercream is grainy or curdled, keep beating until smooth.’, ‘Pour glaze in one swift motion to avoid streaks; warm slightly if it thickens too fast.’, ‘Brush coffee syrup evenly but do not soak sponge layers excessively to avoid sogginess.’, ‘Chill cake before slicing for neat, professional-looking slices.’, ‘Use a hot knife dipped in hot water and dried between cuts for clean edges.’, ‘For dairy-free version, substitute butter with vegan margarine and heavy cream with coconut cream.’, ‘For gluten-free, use a suitable gluten-free flour blend instead of all-purpose flour.’]
