Step 1

Preheat the oven to 350 degrees Fahrenheit.

Step 2

Dump peaches, walnuts, and vanilla extract into a 9x13 inch baking dish and stir until completely mixed together.

Step 3

Sprinkle the dry cake mix on top of the peaches.

Step 4

Pour the half and half and melted butter over the top of the cake mix. Gently tilt the pan back and forth to help the liquids cover the top. If needed, grab a fork and gently stir some of the dry spots.

Step 5

Bake in the oven for 45 minutes or until the top turns golden brown and starts to bubble.

Step 6

Plate and serve warm with a big scoop of vanilla ice cream. Top with whipped cream if desired.
