Creating your Elderflower & Strawberry Fields Gateau can be straightforward with these step-by-step instructions:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Mix Dry Ingredients: In a large bowl, combine the flour, baking powder, and salt. Set aside.
3. Cream Butter and Sugar: In another bowl, cream together the softened butter and granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Beat in the eggs one at a time, then add the vanilla extract and elderflower cordial.
5. Combine Mixtures: Gradually mix the dry ingredients into the wet mixture, alternating with the milk. Stir until just combined.
6. Divide Batter: Pour the batter evenly into the prepared cake pans.
7. Bake: Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool Cakes: Remove from the oven, let them cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
9. Prepare Whipped Cream: In a mixing bowl, whip the heavy cream with powdered sugar until soft peaks form.
10. Assemble the Gateau: Once the cakes are completely cool, place one layer on a serving plate. Spread a layer of whipped cream on top, then add a layer of sliced strawberries.
11. Add Second Layer: Place the second cake layer on top of the strawberries, and spread more whipped cream over the top. Decorate with remaining strawberries and edible flowers if desired.

By following these steps, you will create a stunning Elderflower & Strawberry Fields Gateau that will impress everyone!
