Sweet & Simple Bake #1 - Victoria Sandwich Cake

Here is my first food blog challenge, compliments of Sweet & Simple Bakes! This challenge was fun for me because I have never made a cake quite like this one before - no chocolate in sight! I do not have scales so it was a bit difficult to do the measurement conversions from the original, but the end result was delicious. Also, I substituted some homemade raspberry cake filling for the jam so there was an extra challenge :) Here is the original recipe and my own simple alterations and substitutions...

Ingredients:

The sponge
175g (6oz) unsalted butter, at room temperature
175g (6oz) caster sugar
3 eggs, at room temperature, beaten
175g (6 oz) self-raising flour
Pinch of salt

*My sponge
3/4 cup butter, room temperature
3/4 cup + 2 tbsp sugar
3 eggs, room temperature (beaten)
3/4 cup + 2 tbsp flour

For The Filling
4-6 tbsp strawberry jam, or your own choice of flavour
1 tbsp caster sugar

*My filling
2 cups raspberries
1/2 cup water
1/4 cup sugar
1.5 tbsp cornstarch

-Bring berries and 1/3 cup water to a boil. Simmer for 10-15 minutes.
-Strain the berry mixture and return to heat.
-Add cornstarch to remaining water. Whisk into berry mixture.
-Add sugar and bring to a boil. Simmer for 8-10 minutes.
-Cool completely.

Buttercream (optional)
75g (3 oz) unsalted butter, at room temperature 175g (6 oz) icing sugar Few drops of vanilla extract

*I opted out of the buttercream.

Steps:

-Cream butter and sugar together in a mixing bowl until the mixture is pale in colour and light and fluffy.

-Add beaten egg, a teaspoon at a time, beating well after each addition.
-Sift flour and salt and carefully add to the mixture, folding in with a metal spoon or spatula.
-Bake in greased pan(s) for 25-30 minutes, until golden and pulling away from sides. (*I used one greased 8-inch spring-form pan)
-Let cool completely, cut in half (if applicable), and add filling.
-Dust with icing/caster sugar.
