Baking heart-shaped cakes - it's that easy

Pink cake batter is poured into a loaf pan lined with baking paper, with a bouquet of pink-and-white flowers in the background.

Step 1: Prepare the pink dough

Preheat the oven to 180 degrees (top/bottom heat). Lightly grease the loaf tin if necessary and line with baking paper. Beat the butter, sugar and salt until light in colour. Gradually beat in the eggs for 30 seconds at a time. Stir in the vanilla paste and lemon zest. Mix the flour and baking powder and fold into the egg mixture with the milk. Colour the batter pink or red and pour into the baking tin. Smooth out and bake in the preheated oven for approx. 55 mins. Don't forget to test with a skewer. Remove from the oven, leave to rest briefly, then lift out of the tin and leave to cool on a cooling rack.

A baked pink pound cake is sliced.

Step 2: Prepare pink hearts

Cut the cooled red cake into slices about 2-3 cm wide.

A heart-shaped cutter is used to cut a heart shape out of pink cake slices.

Step 3: Cutting out hearts

Use a heart cookie cutter to cut out red hearts. Then prepare the light-coloured dough as in step 1 (only without the colour) and fill into a piping bag or freezer bag.

Light-colored batter is piped into a loaf pan using a piping bag, forming the bottom layer of a surprise-inside cake.

Step 4: Pour in the light-coloured batter

Pour a layer of the light-coloured batter into the baking tin lined with baking paper - you can use a piping bag for this.

Pink heart-shaped cake pieces are placed in the center of the light batter in the pan.

Step 5: Insert the pink hearts

Arrange the red hearts into small ‘packets’ and place them close together in the centre of the mould.

Light-colored batter is piped around the heart pieces into the loaf pan using a piping bag.

Step 6: Pour in the light-coloured batter

Pour the light-coloured batter into the sides of the mould first, then onto the hearts. The red hearts should be completely covered.

The surface of the light dough is smoothed with a dough scraper.

Step 7: Bake the cake

Depending on the size of the red hearts, some of the light-coloured batter may be left over. If the tin is too full, the cake may not bake upwards, but out of the side of the tin and won't have a nice shape. 

Bake the cake in the preheated oven for about 55 minutes. Don't forget to test with a skewer. Remove from the oven, leave to rest briefly, then lift out of the tin and leave to cool on a cooling rack.

After baking, the cake is covered with white icing.

Step 8: Make the icing

Mix the icing sugar and lemon juice to make a thick icing and pour over the cooled heart cake.

A red heart-shaped sugar decoration is placed on the cake's icing.

Step 9: Decorate the cake

Decorate the cake immediately with sugar sprinkles. Don't wait too long, otherwise the icing will dry and the sprinkles will no longer hold.

Done!

The cake will keep for approx. 2-3 days in an airtight container. Tip: If you don't have any food colouring, you can replace some of the flour in the red dough with baking cocoa and bake a cake with a chocolate heart.
