01 - Preheat the oven to 350°F. Grease and line two 8-inch square cake pans with baking paper.
02 - In a large mixing bowl, beat butter and granulated sugar together until light and fluffy. Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
03 - In a separate bowl, whisk together all-purpose flour, baking powder, salt, ground ginger, ground cinnamon, and ground nutmeg.
04 - Add the dry ingredients to the creamed mixture alternately with milk, starting and ending with flour blend. Mix just until combined.
05 - Divide the batter evenly between the prepared pans. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean.
06 - Allow cakes to cool in pans for 10 minutes. Turn out onto a wire rack and cool completely.
07 - In a clean bowl, beat softened butter until creamy, then gradually add powdered sugar. Stir in vanilla extract and add milk, a tablespoon at a time, until smooth and spreadable.
08 - Once cakes are completely cool, cut into shapes for the house structure. Use one cake for the base and roof, and the other cake for the walls and any extra features. Irregular cuts add to the playful design.
09 - On a cake board or large plate, arrange the cake pieces into a house form. Use frosting as adhesive between cake sections. A leaning or slightly collapsed construction enhances the whimsical effect.
10 - Attach candies, mini marshmallows, pretzel sticks, and chocolate chips to the house using extra frosting as glue. Create snow, icicles, and fun details; fill in any gaps or ‘disasters’ with more frosting.
11 - Sprinkle generously with colored sugar and sprinkles. Allow assembled cake house to set for 30 minutes before serving or displaying.
