Preheat the oven to 350F. Line a 9×9 baking pan with parchment paper (or if doing a layer cake, three 8″ cake pans with parchment paper).

Add the sugar, brown sugar, melted vegan butter, vegan sour cream, vanilla extract, espresso powder, and coffee to a large bowl. Whisk until combined. Then add in the cocoa powder, and whisk until there are no clumps of cocoa powder in the mixture. Then add in the baking powder, baking soda, and sea salt, and whisk to evenly distribute the leavening ingredients throughout the batter.

Add in the flour and dairy-free milk, and whisk just until the dry ingredients are incorporated into the chocolate cake batter.

Pour the cake batter into the prepared pan, and place into the oven to bake for 50-55 minutes. If you’re baking as a layer cake, the layers will only need 30-35 minutes. As a sheet cake in a 9×13 pan, about 35-40 minutes.

Remove the cake from the oven and allow the cake to cool in the pan for 10 minutes. Then transfer to a cooling rack to cool completely. Do not frost until the cake is fully cooled.

In a medium bowl with hand mixer, cream together the vegan butter and cream cheese until fluffy, about 3 minutes. Then add in the espresso, and cream again until combined. Add in the powdered sugar in 1 cup increments, mixing between each cup to integrate until fluffy. Finally, finish with the vanilla extract and sea salt, mixing until incorporated.

Top the cooled tiramisu chocolate cake with the espresso cream cheese frosting and spread to the edges of the cake. Dust with cocoa powder, and top with shaved chocolate or vegan chocolate covered espresso beans. Enjoy!
