In India, baking is becoming increasingly popular, and more people get involved in experimenting with baking using different ingredients and techniques. The freshness of lemon gives a refreshing lift, and the bursts of juiciness from each bite of blackberries. This guide will walk you through a simple, yet effective recipe followed by some of the most essential tips to make sure your cake turns out perfect every time.

Recipe for a Fluffy Lemon Blackberry Layer Cake

Ingredients:

  • 2 ½ cups all-purpose flour
  • 1 ½ tsp baking powder
  • ½ tsp baking soda
  • ¼ tsp salt
  • 1 cup unsalted butter, softened
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 tbsp lemon zest
  • 3 tbsp fresh lemon juice
  • 1 cup buttermilk
  • 1 tsp vanilla extract
  • 1 ½ cups fresh blackberries

For the Frosting:

  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar
  • 2 tbsp fresh lemon juice
  • ½ cup blackberry compote
  • ½ tsp vanilla extract

Method:

Preheat the oven to 175°C. Grease and line three 8-inch cake pans. Whisk flour, baking powder, baking soda, and salt together in a bowl. Beat butter and sugar together in another bowl until creamy. Add eggs and mix well. Stir in lemon zest, lemon juice, and vanilla extract. Gradually fold in dry ingredients with buttermilk, till batter is smooth. Toss blackberries with a little flour and fold gently into batter.

Pour the batter into the cake pans and bake for 25-30 minutes. Let the cake cool completely. To make the frosting, beat the butter until creamy, then add powdered sugar, lemon juice, vanilla, and blackberry compote. Mix until it is smooth.

For assembly, arrange layers of cake with frosting plus a thin layer of compote on top of each cake. Frost the exterior, chill, then serve.

10 Tips for The Ultimate Guide to Baking a Fluffy Lemon Blackberry Layer Cake

Use Fresh Lemon Juice and Zest

Fresh lemon juice adds brightness to the cake, while zest deepens the taste. Do not use bottled juice since it does not have the same vibrancy effect. When zesting the lemon, do that directly over the batter so both essential oils are collected and combined together.

Coat Blackberries with Flour Before Adding

Blackberries always sink to the bottom while baking. Coating them lightly with flour helps prevent them from clumping and allows them to stay dispersed in the cake.

Use Measuring Cups and Spoons

Baking is a science and even tiny inaccuracies in the measurements will cause a change in the outcome. Use measuring cups and spoons for accurate measurement. Always level off dry ingredients and never pack flour in a measuring cup too tightly.

Avoid Overmixing

Overmixing will likely yield a rather heavy cake as opposed to an airy sponge cake. Fold together just until mixed. This retains the structure, not to mention tenderness, of the mix.

Use room-temperature ingredients

Cold butter and eggs aren't going to be mixed thoroughly into the batter, thus ensure all ingredients are at room temperature before starting for a smoother mix.

Bake at the Right Temperature

An over-heated oven could cause cakes to rise unevenly and become excessively browned. Stick to 175°C, and if possible, use an oven thermometer.

Cool Cakes Completely Before Frosting

This is an important step. Frosting a cake that has been freshly baked means melting and sliding layers. The cakes must be cooled completely before assembling so the structure will remain intact and looking neat.

Make the Frosting Light and Stable

Butter should be softened but not melted. Whip frosting until light and airy, avoiding too much liquid that can make it runny.

Chill Before Slicing for Clean Layers

Refrigerate the cake for alteast 30 minutes before slicing. This helps to set the frosting to get clean defined layers without smudges.

Experiment with Garnishes

Fresh blackberries, edible flowers, or a light dusting of powdered sugar enhance presentation. A few artistic swirls of blackberry compote on top can add elegance to the final cake.
