Preheat the oven to 350°F (175°C). Line a rimmed half sheet pan with parchment paper and lightly spray it with nonstick spray.
STEP 1: PREP THE OVEN AND PAN
STEP 2: MELT THE BUTTER AND WATER
In a medium saucepan, combine the butter and water over low to medium heat. Melt gently, making sure the mixture does not boil.
STEP 3: MIX THE DRY INGREDIENTS
In a large bowl, sift together the flour, sugar, salt, and baking soda.
STEP 4: MAKE THE BATTER
Pour the warm butter-water mixture into the dry ingredients and stir until combined. Add the vanilla, sour cream, and eggs, then mix until the batter is smooth and lump-free.
STEP 5: BAKE
Pour the batter evenly into the prepared pan.Bake for 15–20 minutes, or until the internal temperature reaches 205°F and the cake is set.
STEP 6: START THE ICING BASE
Melt the butter, then mix in half of the powdered sugar, stirring or whisking until smooth.
STEP 7: FINISH THE ICING
Add the sour cream, salt, and vanilla, mixing until fully combined. Add the remaining powdered sugar and whisk until the icing is smooth and glossy.
STEP 8: ICE THE CAKE
Pour or spread the icing over the cooled cake, starting in the center and gently working outward so it naturally spreads to the edges.
