I believe the title of this recipe is the perfect answer to any question about how much exactly I enjoy coffee. A coffee coffee cake actually fits perfectly into the image people already have of me in regards to caffeine.
Sweet jokes aside, it is a marvellous little cake with a tender crumb, rich brownie filling, and a wonderful crumb topping. The coffee flavour is prominent, but that is the point. I encourage you to reduce or increase the amount of espresso to your liking, especially if you are not serving the cake to children.
Feel free to add a tiny splash of your favourite coffee liqueur to the batter itself, it will be an excellent addition. Just make sure not to add too much, because we still need the cake to bake through and have a lovely crumb texture.
I've served it straight from the oven, as well as completely cooled, and I have to say I do enjoy it either way. So serve it to your liking, maybe even including a tiny scoop of vanilla ice cream, and enjoy!

Ingredients
For the espresso coffee cake
90 grams plain flour10 grams unsweetened cocoa powder
small pinch of cardamom
30 grams ground toasted walnuts, finely ground
50 grams granulated sugar
50 grams brown sugar
3/8 teaspoon baking soda
1/2 teaspoon baking powder
1/4 teaspoon salt
110 millilitres carbonated water
1 tablespoon instant espresso powder
10 millilitres boiling water
25 millilitres neutral oil
1 teaspoon apple cider vinegar
2 teaspoons vanilla bean paste
For the brownie filling
15 grams unsweetened cocoa powder15 grams icing sugar
30 grams vegan block butter
30 grams dark chocolate (70%), chopped
45 millilitres soy milk
1/2 teaspoon vanilla bean paste
25 grams plain flour
For the crumb topping
20 grams vegan block butter, melted20 grams granulated sugar
40 grams plain flour

Preparation
Start by making the crumb topping. Mix the melted vegan block butter with the sugar and flour until big pieces of crumble form. Place it in a little bowl, and store in the refrigerator until needed.
Turn the oven on to preheat to 180°C and line a small rectangle cake pan (12x12 cm) with baking parchment, bottom and sides. It is best to use a deeper cake pan, so the cake can rise nicely and that there is enough room for the topping.
Just before making the cake batter, make the brownie batter filling. Place the vegan butter, dark chocolate, soy milk, and vanilla into a small saucepan, and whisk well. Sift in the cocoa powder and icing sugar, and whisk well. Place the pan over medium heat, and gently melt everything together until smooth, but do not let it boil. Remove from the heat, add in the flour, and mix until just combined. Set it aside at room temperature or pour it into a piping bag.
Sift together the flour, cocoa powder, cardamom, baking powder, baking soda, and salt, add in the ground walnuts and both types of sugar, and whisk to combine. Separately whisk together the instant espresso powder with the boiling water, and add it to the dry ingredients along with the rest of the wet ingredients. Mix until just combined, so the cake stays soft.
Pour the cake batter into the prepared pan and place it immediately in the preheated oven, for just 15 minutes, so the surface firms up slightly. After about 15 minutes or so, take the cake out of the oven, add the brownie filling and the crumb topping, and continue to bake for another 15-20 minutes, for a total of 35 minutes. Make sure you check the cake early on, so it doesn't overbake.
Once baked, remove from the oven and let it cool down completely in the pan. Serve with coffee. Yields 8 servings.
