Step‑by‑Step Instructions for Easy Coffee Cake
Step 1: Preheat the Oven
Start by preheating your oven to 160ºC (140ºC fan). This ensures a perfectly baked Easy Coffee Cake. While the oven warms up, you’ll have time to prepare the baking tins and cake batter, setting you up for a smooth baking process.
Step 2: Prepare the Tins
Line two 20cm round sandwich tins with greaseproof paper, which will make it easier to remove the cakes once they’re baked. As you set up your pans, you’ll create the perfect home for your cake batter, ensuring it doesn’t stick during baking.
Step 3: Mix the Cake Batter
In a large mixing bowl, combine all the cake ingredients: instant coffee, plain flour, baking powder, soft light brown sugar, margarine or butter, eggs, milk, and salt. Blend everything together until the mixture is well combined and smooth, which should take about 3-5 minutes.
Step 4: Bake the Cake Layers
Divide the batter evenly between the prepared tins. Place them in the preheated oven and bake for 30-35 minutes, until the edges begin to pull away from the sides and a toothpick inserted into the center comes out clean. Your kitchen will soon fill with the heavenly scent of baking coffee cake!
Step 5: Cool the Cakes
Once baked, allow the cakes to cool in their tins for about 10 minutes. This will make it easier to lift them out without breaking. After 10 minutes, carefully transfer the cakes to a wire rack to cool completely, helping them maintain a light and fluffy texture.
Step 6: Prepare the Buttercream
For the rich coffee buttercream, dissolve the instant coffee powder in a small amount of boiling water and let it cool. In a separate bowl, beat the room temperature butter with vanilla extract until smooth and creamy. This creates a luscious base for your frosting.
Step 7: Mix the Buttercream Ingredients
Gradually sift in the icing sugar while mixing the butter mixture, ensuring a smooth consistency. Once combined, add the cooled coffee mixture to the frosting and mix until everything is well incorporated. You want it to be fluffy and spreadable for your Easy Coffee Cake.
Step 8: Assemble the Cake
Now it’s time to bring it all together! Place one cake layer on a serving plate and spread about one-third of the coffee buttercream on top. Carefully add the second layer and top it with the remaining buttercream, creating a lovely, creamy finish on your Easy Coffee Cake.
Step 9: Decorate (Optional)
For a professional touch, pipe decorative buttercream around the edges of your cake. This isn’t just for looks; it also adds extra flavor! Enjoy the creative process and feel free to make the cake uniquely yours, whether it’s with sprinkles or chocolate shavings.
