What Ingredients You Will Need

This decadent chocolate cake with espresso buttercream frosting uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Many of these are pantry staples, and a few tips on choosing the best options can help you get the best results.

• For the Chocolate Cake:
  • All-purpose flour – 1¾ cups (220g), for a tender crumb
  • Granulated sugar – 2 cups (400g), sweetens perfectly without overpowering
  • Unsweetened cocoa powder – ¾ cup (75g), I prefer Dutch-processed for richness
  • Baking powder – 1½ teaspoons
  • Baking soda – 1½ teaspoons
  • Salt – 1 teaspoon
  • Buttermilk – 1 cup (240ml), room temperature (adds moisture and tang)
  • Vegetable oil – ½ cup (120ml), keeps the cake moist
  • Large eggs – 2, room temperature
  • Vanilla extract – 2 teaspoons
  • Hot brewed espresso or strong coffee – 1 cup (240ml), freshly brewed (enhances chocolate flavor without making it taste like coffee)
• For the Espresso Buttercream Frosting:
  • Unsalted butter – 1 cup (227g), softened (I recommend Kerrygold for creaminess)
  • Powdered sugar – 4 cups (480g), sifted for smooth texture
  • Espresso – 2 tablespoons, cooled but freshly brewed
  • Vanilla extract – 1 teaspoon
  • Salt – a pinch, to balance sweetness

Substitution tips: Use almond flour for a gluten-free cake version (note: texture will be slightly denser). Swap dairy buttermilk for coconut milk mixed with lemon juice if you need a dairy-free option. And if you’re sensitive to caffeine, decaf espresso works perfectly well here.

Equipment Needed

• Two 9-inch (23cm) round cake pans – nonstick or greased and lined with parchment paper
• Mixing bowls – medium and large sizes
• Electric mixer – stand or hand mixer, for smooth batter and frosting
• Measuring cups and spoons – for accuracy
• Whisk and spatula – for combining ingredients and scraping bowls
• Cooling rack – to cool the cakes evenly

If you don’t have two cake pans, you can bake one at a time, but it takes longer. For budget-friendly options, silicone spatulas and stainless steel bowls work just fine and clean up easily. I’ve found that a good quality electric mixer really helps get that light, fluffy buttercream without arm cramps!

Preparation Method

1. Preheat & Prep: Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper for easy removal.
2. Mix Dry Ingredients: In a large bowl, sift together 1¾ cups (220g) flour, ¾ cup (75g) cocoa powder, 2 cups (400g) sugar, 1½ teaspoons baking powder, 1½ teaspoons baking soda, and 1 teaspoon salt. Whisk them well to combine evenly.
3. Combine Wet Ingredients: In another bowl, whisk 1 cup (240ml) buttermilk, ½ cup (120ml) vegetable oil, 2 large eggs, 2 teaspoons vanilla extract, and 1 cup (240ml) hot brewed espresso until smooth. The espresso should be hot but not boiling to avoid curdling the eggs.
4. Make the Batter: Slowly pour the wet mixture into the dry ingredients, mixing gently with an electric mixer on medium speed for about 2 minutes. You want a smooth, glossy batter that’s pourable but not runny. If the batter looks too thick, a splash of extra buttermilk can help.
5. Pour & Bake: Divide the batter evenly between the prepared pans. Tap the pans gently on the counter to release air bubbles. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. The cakes should spring back when lightly pressed.
6. Cool Completely: Let the cakes cool in the pans for 10 minutes before turning them out onto a wire rack. Cool completely before frosting to avoid melty buttercream.
7. Make the Espresso Buttercream: Beat 1 cup (227g) softened unsalted butter with an electric mixer until creamy (about 2 minutes). Gradually add 4 cups (480g) sifted powdered sugar, mixing on low speed. Add 2 tablespoons cooled espresso, 1 teaspoon vanilla extract, and a pinch of salt. Increase speed to medium-high and beat until fluffy and smooth, about 3-5 minutes. If frosting is too stiff, add a teaspoon of milk; if too soft, add more powdered sugar.
8. Assemble the Cake: Place one cake layer on a serving plate and spread a generous amount of frosting on top. Add the second layer and cover the entire cake with the remaining frosting. For a professional touch, use an offset spatula to create swirls or smooth the surface.

Pro tip: Keep your butter at room temperature (not melted) for the best frosting texture, and don’t rush cooling – warm cakes can cause frosting to melt.

Cooking Tips & Techniques

When it comes to this decadent chocolate cake with espresso buttercream frosting, a few tricks can make all the difference. First, don’t skip sifting your dry ingredients; it prevents lumps and helps the cake rise evenly. Also, adding hot espresso to the batter might sound intimidating, but it really amps up the chocolate flavor without making the cake taste like coffee.

One common mistake I’ve seen (and made!) is rushing the frosting stage. If your butter is too cold, the frosting will be clumpy; too warm, and it gets greasy. I usually take butter out an hour before starting, especially if the kitchen is chilly. When mixing powdered sugar into the butter, add it gradually to avoid a sugar cloud in your kitchen.

Timing is key. Baking both layers at once saves time, but if your oven has hot spots, rotate the pans halfway through baking. And multitasking? Prep your frosting while cakes cool to keep things moving smoothly.

Variations & Adaptations

Want to switch things up? Here are some delicious ways to customize this decadent chocolate cake with espresso buttercream frosting:

• Gluten-Free: Swap all-purpose flour for a 1:1 gluten-free baking blend. Texture might be a tad denser but still delicious.
• Vegan Version: Use flax eggs (2 tablespoons ground flax + 6 tablespoons water), coconut oil instead of vegetable oil, and a dairy-free milk like almond or oat milk with a splash of vinegar instead of buttermilk. Use vegan butter for frosting and adjust powdered sugar for sweetness.
• Seasonal Twist: Add a teaspoon of orange zest to the batter for a bright citrus note or fold in ½ cup of fresh raspberries between the layers for a fruity surprise.

For a personal twist, I once added a pinch of cinnamon to the frosting – it gave a subtle warmth that felt perfect for chilly evenings. And if you prefer a lighter frosting, try folding in some whipped cream just before assembling.

Serving & Storage Suggestions

This decadent chocolate cake with espresso buttercream frosting is best served at room temperature to let those rich flavors shine through. Slice generously and pair with a glass of cold milk or a cup of black coffee to complement the espresso notes.

Leftovers? Store the cake covered in the refrigerator for up to 4 days. Bring slices to room temperature before serving; flavors deepen as the cake rests, making it even better the next day. For longer storage, wrap individual slices tightly and freeze for up to 2 months. Thaw overnight in the fridge and then let warm on the counter before digging in.
