Start by melting your dark chocolate. This can be done by breaking up a bar of chocolate, placing the chunks into a heatproof bowl over a saucepan of gently simmering water. Allow it to sit there until it melts fully, which usually takes around 5-7 minutes. Allow to cool for at least 10 minutes after at room temperature.
Next, drain a can of chickpeas and retain the aquafaba in a large mixing bowl. Using a handheld electric mixer, whisk the aquafaba for at least 10-12 minutes, until stiff peaks form. Be patient with it, as the result is worth it 100%!
Pour in the lime juice and the maple syrup, whisking for a further 2-3 minutes. Then, pour in the dark chocolate at the same time as whisking, taking around 30 seconds to complete the entire process.
Use a rubber spatula to fold in the chocolate chips. Divide between jars or glasses and leave to chill in the fridge for at least 1 hour before serving.
