In a small bowl, combine the vegan pastry cream and the yogurt until smooth. Set aside.
Pancakes
Whisk together the dry ingredients. Add the flour, sugar, baking powder, and salt to a medium-sized mixing bowl. Whisk to combine.
Pour in the wet ingredients. Next, pour in the plant-based milk, yogurt, melted butter, vanilla extract, and vinegar.
Whisk. Whisk until combined, with almost no clumps remaining. Do not overmix, though, or your pancakes will be gummy.
Let it sit. Allow the batter to rest for 5-10 minutes while you preheat the skillet.
Heat a non-stick skillet. Heat a non-stick skillet over medium heat. Once hot, add a teaspoon of oil and use a kitchen paper towel to very lightly grease the skillet.
Pour the batter. Pour about 3 tablespoons of the batter into the skillet and spread it slightly into a round shape, approximately 4 inches (10 cm) in diameter. Repeat 2-3 times, depending on the size of your skillet.
Cook until golden brown. Cook the pancakes for 2-3 minutes, or until holes form on the surface and the bottoms are golden brown.
Flip. Use a spatula to carefully flip the pancakes. Cook for an additional 2-3 minutes on the other side, or until golden brown. Transfer to a plate and repeat with the remaining batter.
Allow to cool. Allow the pancakes to cool for at least 15 minutes.
To Assemble
Make the dip. Add the brewed espresso, sugar, and khalua (if using) to a deep plate. Stir to combine. Dip one of the pancakes into the espresso for 1-2 seconds on each side.
Assemble. Arrange the pancake on a plate. Then, spread 2-3 tablespoons of the vanilla cream on top. Repeat these steps three times, or until you have a stack of four pancakes layered with the cream. Finish with a layer of vanilla cream.You should be able to make two stacks of 4 pancakes.
Dust with cocoa powder. Use a fine sieve to dust the pancakes with unsweetened cacao powder. Serve immediately!
Notes
If you don't have time to make the pastry cream: simply replace it with thick coconut yogurt or vegan Greek yogurt. Mix it with 2-3 tablespoons of sugar (adjust to taste) and 1/2 tsp of vanilla extract.
