Why Make a Cake Mix in a Jar?
Preparing a dry cake mix ahead of time saves effort and gives you a ready-made base for a variety of cakes. Keep a jar in the pantry and you’ll always have the foundation for an attractive, homemade dessert.
Dry Mix Ingredients:
- 2 1/3 cups all-purpose flour
- 1/3 cup nonfat dry milk
- 3 teaspoons baking powder
- 3/4 teaspoon salt
- 1 1/2 cups white sugar
- 1/2 cup plus 1 tablespoon shortening
How to Prepare the Jar Mix:
- Combine all dry ingredients in a large bowl.
- Cut in the shortening until the mixture looks like coarse crumbs.
- Pack the mixture into a clean jar, seal it, and label it. Store in a cool, dry place—it will stay fresh for months.

How to Turn the Jar Mix into Pineapple Upside-Down Cake
When you’re ready to bake, transform the jar mix into a classic pineapple upside-down cake with minimal effort.
Additional Ingredients:
- 2 eggs
- 1 cup water
- 1 teaspoon vanilla extract
- 1 jar of the prepared cake mix
Directions to Make the Cake Batter:
- Preheat the oven to 350°F (175°C).
- Grease and flour a 9×13-inch baking pan.
- In a mixing bowl, beat the eggs with the water and vanilla. Add the jar mix and stir until smooth.

Assemble the Upside-Down Layer
The caramelized fruit layer is what makes this cake special. Follow these simple steps to create it:
- Melt 1/4 cup (4 tablespoons) of butter in the bottom of the prepared pan.
- Evenly sprinkle 1 cup of brown sugar over the melted butter.
- Arrange drained pineapple slices on top of the sugar, placing maraschino cherries in the centers or between slices for color.
- Pour the prepared batter evenly over the fruit and sugar layer.

Bake, Invert and Serve
Bake the cake for 30–35 minutes, or until a toothpick inserted into the center comes out clean. Let it cool in the pan for about 5 minutes, then invert the cake onto a serving platter so the fruit and caramel are on top. Allow it to cool a little more before slicing.
Tips and Variations
- Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for extra indulgence.
- For a tropical twist, add a tablespoon or two of rum or rum extract to the batter—this complements the pineapple nicely. (Optional; omit for children or non-alcoholic servings.)
- If you prefer crushed pineapple, drain it well and spread it evenly over the sugar before pouring the batter.
This Pineapple Upside-Down Cake Mix in a Jar is a simple, flexible way to keep a delicious dessert ready to go. With a little prep and pantry-friendly ingredients, you can produce an impressive homemade cake any time.
