### Classic Victoria Sponge Cake Recipe

#### Ingredients:

**For the Sponge Cake:**
- 200g (7 oz) unsalted butter, softened
- 200g (7 oz) granulated sugar
- 4 large eggs, at room temperature
- 200g (7 oz) all-purpose flour
- 2 tsp baking powder
- Pinch of salt
- 1 tsp vanilla extract
- 2-3 tbsp milk (optional, for adjusting consistency)

**For the Filling:**
- 100g (3.5 oz) unsalted butter, softened
- 150g (5.3 oz) icing sugar (powdered sugar)
- 1 tsp vanilla extract
- 200g (7 oz) strawberry jam (or any jam of your choice)

**For Decoration:**
- Icing sugar for dusting
- Fresh strawberries or other berries (optional)

#### Equipment Needed:
- Two 8-inch (20 cm) round cake pans
- Mixing bowls
- Electric mixer or whisk
- Spatula
- Cooling rack
- Sifter
- Measuring scales or cups
- Parchment paper (optional)

#### Instructions:

**Step 1: Prepare the Pans**
1. Preheat your oven to 180°C (350°F).
2. Grease two 8-inch round cake pans with butter and line the bottoms with parchment paper for easy removal. Dust the sides with flour and tap out any excess.

**Step 2: Make the Cake Batter**
1. In a large mixing bowl, beat the softened butter and granulated sugar together using an electric mixer on medium speed until the mixture is light and fluffy (about 4-5 minutes). This step is crucial as it incorporates air, which helps the cake to rise.
2. Add the eggs one at a time, mixing well after each addition. Scrape down the sides of the bowl as necessary. Add the vanilla extract and mix until combined.
3. In a separate bowl, sift together the all-purpose flour, baking powder, and salt. Gradually add this dry mixture to the wet mixture, folding it in gently with a spatula or wooden spoon until just combined. Be careful not to over-mix, as this can make the cake dense.
4. If the batter is thick, you can add 2-3 tablespoons of milk to achieve a slightly looser consistency, which will help the cake rise better.

**Step 3: Bake the Cakes**
1. Divide the cake batter evenly between the two prepared pans, smoothing the top with a spatula.
2. Bake in the preheated oven for about 25-30 minutes, or until the cakes are golden brown and a skewer inserted into the center comes out clean.
3. Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes. Then, turn them out onto a cooling rack to cool completely.

**Step 4: Prepare the Filling**
1. While the cakes are cooling, prepare the buttercream filling. In a bowl, beat the softened butter until creamy.
2. Gradually add the icing sugar, beating well after each addition until the mixture is smooth and fluffy. Add the vanilla extract and mix until combined. If the buttercream is too thick, you can add a little milk to reach your desired consistency.

**Step 5: Assemble the Cake**
1. Once the cakes have completely cooled, place one layer on a serving plate or cake stand. Spread a generous layer of strawberry jam over the top of the first layer.
2. Next, spread the buttercream filling over the jam, smoothing it out with a spatula.
3. Place the second layer of cake on top, pressing down gently to secure it in place.

**Step 6: Decorate**
1. To finish the cake, dust the top with icing sugar using a sifter. For an extra touch, you can decorate the top with fresh strawberries or other berries.
2. Slice the cake and serve with a cup of tea or coffee.

### Tips and Variations:
- **Flavor Variations:** You can experiment with different flavors by adding citrus zest (like lemon or orange) to the batter or using different flavored jams.
- **Chocolate Version:** For a chocolate sponge, substitute 50g (1.75 oz) of flour with cocoa powder.
- **Storage:** The cake can be stored in an airtight container at room temperature for up to three days or in the refrigerator for up to a week. It also freezes well; just wrap it tightly in plastic wrap and foil.

### Conclusion
The Classic Victoria Sponge Cake is a delightful treat that is both simple and elegant. With its light texture and delicious filling, it is sure to impress your guests. Enjoy baking and sharing this timeless recipe!
