Note 1: I recommend preparing the chocolate ganache at least 2 hours ahead of time to give it ample time to chill and firm up in the fridge. The lava cakes won’t bake properly if the ganache isn’t solid. If you like, you can prepare it up to a few days in advance and simply leave it in the fridge in an airtight container until ready to use.
Note 2: This recipe yields a tiny bit of extra ganache. I used these quantities for the sake of easier measurement.
Measure out 2 oz semisweet chocolate. If using a chocolate bar, give it a coarse chop so it melts faster. Or, weigh out 2 oz chocolate chips.
Microwave instructions: Add plant milk, vegan butter, and chocolate to a microwave-safe bowl. Microwave in 10-second bursts, stirring between, until the chocolate is completely melted. Stir until all ingredients are well-combined.
Stovetop instructions: Add all ingredients to a small saucepan. Heat over medium-high, stirring occasionally, until the chocolate is completely melted and the ingredients are well-combined.
Place the ganache in a sealable container. Cover and refrigerate until solid — about 2 hours. Make sure that the ganache has completely firmed up before making the lava cakes.
