Preheat oven to 350 degrees F (180 degrees C). Prepare 13-by 9-inch (3 L) baking pan, lined with parchment paper.

Cake:

In a bowl, combine biscuit mix, flour and salt. Set aside.

In a mixer bowl, using an electric mixer, mix together granulated and brown sugars, cream cheese and butter on medium speed until soft and creamy, about 4 minutes.

Beat in eggs, one at a time. Add vanilla and almond extract. Stir in biscuit mixture and blend until incorporated.

Pour into prepared pan, spreading to edges with a rubber spatula. Bake in preheated oven until a cake tester inserted into the center comes out clean, 55 to 60 minutes. Let cool in pan for 10 minutes, then invert onto a rack to cool completely.

Strawberry Sauce:

In a large skillet, cook sugar and butter over low heat until butter has melted, 2 to 3 minutes.

Add sliced strawberries, stirring until sauce turns red from the berries.

Spoon into center of cake and serve a little with each slice.
