These Chocolate Cube Pound Cakes are rich, tender, and moist with a slightly dense classic velvety pound cake texture and smothered with a melty chocolate drip on top. Perfect for chocolate lovers and there is no sharing required!
Using a hand mixer or stand mixer fitted with a paddle attachment, cream together the butter and granulated sugar until pale and fluffy. Scrape the side with a spatula.
Add eggs, vanilla extract, lemon zest, and lemon juice. Beat until well combined.
Sift in all-purpose flour, cocoa powder, baking powder, and salt. Beat on the lowest speed until just combined. Don't overmix.
Transfer the batter to a piping bag. Pipe the batter into 8 cavities of cube silicone cake mold (each cavity is 2x2x2-inch/5x5x5 cm) until 75% full. Tap the mold on the working surface a few times to flatten the batter and remove the air bubbles.
Bake for 20-23 minutes or until a toothpick inserted comes out clean.
Cool in the mold for 5 minutes to set, then remove the cakes from the mold. Cool the cakes completely on a cooling rack.
In a heatproof bowl, add chopped dark chocolate and grapeseed oil. Place the bowl over but not touching simmering water in a saucepan (bain-marie) and stir until the chocolate is fully melted. Or you can also microwave it in 30-second intervals, stirring after each, until smooth.
Pour a tablespoon of melted chocolate on top of each cake. Place a tiny edible gold leaf flake for decoration. Serve immediately for melty chocolate experience or let the chocolate set first before serving.
