Mini Coffee and Walnut Cakes Ingredients
Get ready to create a delightful treat!
For the Batter
- Unsalted Butter The main fat for structure and moisture; feel free to substitute with margarine if needed.
- Golden Caster Sugar This adds sweetness and moisture to your cakes; regular white caster sugar works in a pinch.
- Eggs They bind the ingredients together and add richness; using 3 medium eggs is a great alternative to 2 large ones.
- Self-Raising Flour Essential for giving the cakes their lovely structure and lift; you can use all-purpose flour with added baking powder instead.
- Espresso Powder or Instant Coffee Granules This is what infuses your mini coffee and walnut cakes with that robust coffee flavor; brewed espresso is a fine substitute, just measure 2 tablespoons.
- Walnuts They provide a lovely crunch and nutty flavor; pecans or almonds can make a great replacement if you prefer.
For the Buttercream
- Icing Sugar A key to achieving that sweet, smooth texture in your buttercream; no substitutes necessary.
- Salt Enhances the flavor of the buttercream beautifully.
- Additional Espresso Powder (for Buttercream) This adds an extra coffee kick; dissolve it in boiling water as you prepare your frosting.
These Mini Coffee and Walnut Cakes will surely impress with their delightful flavors and textures!
How to Make Mini Coffee and Walnut Cakes
Dissolve Espresso: Begin by dissolving 2 tablespoons of espresso powder in a small bowl with boiling water. Allow it to cool in the fridge while you prep the other ingredients.
Preheat Oven: Preheat your oven to 160°C fan / 180°C conventional. Grease a 12-hole mini cake tin to ensure easy removal later.
Cream Butter and Sugar: In a large bowl, cream together the unsalted butter and golden caster sugar until the mixture is light and fluffy. This vital step incorporates air, giving the cakes a lovely texture.
Add Eggs: Beat in the eggs one at a time, adding a tablespoon of flour with each addition to prevent curdling. This will keep your batter smooth and creamy.
Fold in Dry Ingredients: Gently fold in the self-raising flour, cooled espresso, and chopped walnuts until just combined. Be careful not to overmix; you want the batter light and airy.
Fill and Bake: Spoon the batter evenly into each hole of the mini cake tin, filling them about two-thirds full. Bake for 18-20 minutes or until golden brown and a toothpick inserted in the center comes out clean.
Cool Down: Allow the cakes to cool in the tin for about 15 minutes before transferring them to a wire rack to cool completely. This helps them set properly.
Prepare Buttercream: While the cakes cool, dissolve 1 tablespoon of espresso powder in boiling water and let it cool. In a separate bowl, beat the butter until fluffy, then sift in the icing sugar and salt, mixing until smooth. Fold in the cooled coffee to integrate it fully.
Assemble and Decorate: Once the mini cakes are cool, slice each one in half horizontally. Spread some of the coffee buttercream on the bottom half, place the top half back on, and finish by decorating with additional buttercream and a walnut on top.
Optional: Drizzle with melted chocolate for an extra touch of decadence.

Expert Tips for Mini Coffee and Walnut Cakes
Chill Before Slicing: To ensure the sponge is easy to slice, chill the mini cakes in the fridge for 20 minutes before cutting.
Avoid Overbaking: Keep a close eye on your cakes as they bake. Overbaking can lead to dryness and a crumbly texture, which we definitely want to avoid!
Piping Perfection: Use a 1cm round piping nozzle to create beautifully shaped buttercream droplets a visual delight on your mini coffee and walnut cakes!
Be Gentle While Folding: When combining the dry ingredients with the wet, fold gently. Overmixing can make the cake dense instead of light and fluffy.
Use Fresh Ingredients: Always use fresh espresso powder or coffee granules for the best flavor. Stale coffee can diminish the delightful coffee taste you re aiming for.
Taste Test: Before decorating, taste the buttercream and adjust sweetness as desired. Sweetness levels can vary depending on personal preference!
