Follow these easy steps to create your own Peaches and Cream Granny Cake:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.

2. Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, and salt.

3. Cream Butter and Sugar: In another bowl, cream the softened butter and granulated sugar until light and fluffy.

4. Add Eggs and Vanilla: Beat in the eggs, one at a time, and add the vanilla extract, mixing well.

5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, alternating with the milk. Mix until just combined.

6. Fold in Peaches: Gently fold in the sliced peaches, ensuring they are evenly distributed throughout the batter.

7. Pour Batter: Pour the batter into the prepared baking pan, smoothing the top with a spatula.

8. Bake: Place the pan in the preheated oven and bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean.

9. Cool the Cake: Once baked, remove the cake from the oven and allow it to cool in the pan for 15-20 minutes. Then transfer it to a wire rack to cool completely.

10. Whip the Cream: While the cake cools, prepare the whipped cream by beating the heavy cream with powdered sugar and vanilla extract until soft peaks form.

11. Frost the Cake: Once the cake is cool, spread the whipped cream evenly over the top.

12. Serve and Enjoy: Slice the cake into squares and serve immediately, garnished with additional peach slices if desired.
