Birthday cake

10 pieces · 6 steps

A round platter, two sponge layers and a colourful candle make a cake for any pretend celebration. Choose a toy guest and build their birthday surprise.

Birthday cake

Before you build

Match the shapes

Compare each part with its picture and count its rows of studs. A square brick has two rows of two studs; a long brick has two rows of four. Use the full parts list for the exact shapes and quantities.

Follow the colours

Match the shapes and quantities. The pictures show our colours. Colour names in the steps refer to the pictures. Keep contrasting colours where they help you recognise the model.

Count the studs

The bumps on top are called studs. Count them when a step asks for a gap or an overhang. Put the build on a flat surface and keep its front facing the same way as in the pictures.

Add a little at a time

New pieces keep their colour in each step. Earlier pieces look lighter so you can see what has changed. Each list tells you exactly what to add.

Build together

An adult can read the steps while a child finds the pieces. The counts are for this one model. For two models to stay built, add their parts lists together.

The candle and flame are made from bricks. This cake is for pretend play.

Gather pieces

Match the shapes and quantities. The pictures show our colours. Choose your own colours for the same parts; changing a part’s shape is a different substitution.

A wheeled base counts as one complete part, including its attached wheels.
