Instructions
1. 
Make the Cake:
1 Preheat oven to 350°F (175°C). Grease and line your cake pans.
2 In a bowl, sift and mix: flour, cocoa, espresso powder, baking powder, baking soda, and salt.
3 In a separate large bowl, whisk oil and sugar. Add eggs one at a time, then vanilla.
4 Add the dry mix and buttermilk in batches, mixing gently.
5 Stir in hot coffee last. The batter will be thin — that’s perfect.
6 Divide into pans and bake for 25–30 mins, or until a toothpick comes out with moist crumbs.
7 Cool in pans for 10 min, then transfer to racks to cool completely.
2. Make the Salted Caramel:
1 In a dry saucepan over medium heat, melt the sugar while stirring constantly.
2 When golden and melted, add butter — be careful, it will bubble.
3 Slowly pour in cream while stirring.
4 Stir in salt. Let cool at room temperature (it thickens as it cools).
3. 
Make the Mocha Buttercream:
1 Beat butter until light and fluffy (2–3 min).
2 Add sifted powdered sugar, cocoa powder, espresso powder, and salt.
3 Add vanilla and cream, 1 tbsp at a time, until desired texture is reached.
4 Beat for another 2–3 minutes until smooth and fluffy.
4. Assemble the Cake:
1 Level the cake layers if needed.
2 Spread mocha buttercream between each layer.
3 Frost the outside with the remaining buttercream — smooth or rustic style.
4 Pour cooled caramel on top, letting it drip naturally over the edges.
5 Optional: top with a sprinkle of flaky sea salt, chocolate shards, or espresso beans.
