Diet Icebox Cake

Prepare dark chocolate and tofu.

Drain the tofu and mash it until smooth.

Add unsweetened cocoa powder, erythritol, and vanilla extract to the tofu and mix well.

When the mixture thickens, melt the dark chocolate, add it in, and mix.

Place biscuits or oatmeal in a baking pan, pour the tofu chocolate mixture over, and spread it evenly.

Refrigerate for at least 2 hours until set.

Cut into pieces and serve.
