Total Calorie Estimate for 9-Inch Upside Down Pineapple Cake

Based on typical ingredient amounts used to make a 9-inch upside down pineapple cake, the estimated calorie counts are:

Brown sugar 1 cup 832

Extracts, water, etc. 100
Total 2,520

For a 9-inch upside down pineapple cake, the total calorie count comes out to approximately 2,520 calories.

However, this is just an estimate and the actual calorie count can vary depending on the specific recipe, ingredient brands, and portion sizes.

Calories per Slice

To determine the calories per slice, you can divide the total calories by the number of slices in a 9-inch cake.

Most 9-inch round cakes are cut into 8-12 slices. Using 10 slices as an example:

– Total calories in entire 9-inch cake: 2,520 calories
– Number of slices: 10
– 2,520 calories ÷ 10 slices = 252 calories per slice

So each slice from a 10-slice 9-inch upside down pineapple cake would contain approximately 252 calories.

The calories per slice for different slice counts would be:

Number of Slices Calories per Slice
8 slices 315 calories
10 slices 252 calories
12 slices 210 calories

As you can see, the more slices you cut the cake into, the lower the calories per slice. You can adjust your portion size to control calorie intake.
