Heat the oven to 350F. Grease a 9x13inch cake pan and line with baking paper.

Whisk all the dry ingredients together well. Using a mixer, beat the butter and sugar until pale and fluffy. Add the eggs one at a time and beat until smooth. Add in the vanilla and orange zest and mix, scraping down the sides of the bowl.

Mix the sour cream and milk together in a small jug or cup. Add in half the dry ingredients and half the milk mix. Mix on low until just combined. Add the rest and mix just until there are no streaks of flour.

Pour the batter into the cake pan and bake for about 20 mins or until a toothpick into the middle comes out clean. Allow to cool for 15 mins and then transfer to a cooling rack. Let cool completely before icing.

Marscapone Cream
Whisk all the cream ingredients together.

To assemble
Cut out the mini cakes with a 2-2.5inch round cutter trying to get as many cakes as possible. Pipe or scoop about a teaspoon of the cream on top of the rounds. Add a layer of sliced strawberries to the bottom half and top with the another round. Add a strawberry on top and enjoy!
