Step 1: Prepare the Cake Batter: In a large bowl, combine the yellow cake mix, milk, melted butter, eggs, and vanilla extract. Blend with an electric mixer on low speed for 30 seconds, then increase to medium speed and beat for 2 minutes, or until the batter is smooth and well combined.
Step 2: Bake the Cake: Pour the batter into a greased and floured 9x13 inch baking pan. Bake in a preheated oven at 350F (175C) for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
Step 3: Cool the Cake: Remove the cake from the oven and let it cool completely in the pan on a wire rack. Cooling completely is essential to prevent the peaches and cream from melting and soaking into the cake excessively.
Step 4: Prepare the Peaches: While the cake is cooling, prepare the sliced peaches. Ensure the peaches are ripe but firm enough to hold their shape.
Step 5: Prepare the Cream: In a chilled bowl, whip the heavy cream with an electric mixer until soft peaks form. Gradually add the powdered sugar and almond extract (if using), and continue whipping until stiff peaks form. Be careful not to overwhip, as this can cause the cream to curdle.
Step 6: Assemble the Cake: Once the cake has cooled completely, spread the whipped cream evenly over the top. Arrange the sliced peaches artfully over the whipped cream.
Step 7: Chill and Serve: Cover the cake loosely with plastic wrap and refrigerate for at least 30 minutes before serving. This allows the flavors to meld together and the cream to set slightly.
Optional Tips:
For a richer flavor, substitute the milk with buttermilk or sour cream.
If fresh peaches are not available, use canned peaches in light syrup, drained well.
Add a streusel topping before baking for extra texture and flavor.
For a boozy twist, brush the cooled cake with a simple syrup infused with peach liqueur or rum before adding the cream and peaches.
