• 280–350 calories for rhubarb coffee cake

• 300–400 calories for rhubarb crumble cake

Rhubarb Cake Calories Per 100g

For more accurate tracking, many people prefer measuring food by weight.

On average:

• Rhubarb cake calories per 100g: 230–320 calories

Macronutrient breakdown per 100g typically looks like this:

• Carbohydrates: 35–45g

• Sugar: 18–28g

• Fat: 10–18g

• Protein: 3–5g

This makes rhubarb cake moderately calorie-dense compared to fresh fruit but lighter than heavily frosted cakes.

Where Do Rhubarb Cake Calories Come From?

Rhubarb itself is very low in calories. Fresh rhubarb contains only about 21 calories per 100g.

Most rhubarb cake calories come from:

• Sugar

• Butter or oil

• Flour

• Toppings such as streusel

Calories from Sugar

Sugar is one of the largest contributors to total rhubarb cake calories. Many recipes include one to two cups of sugar, which significantly increases energy content.

Calories from Fat

Butter and oil are calorie-dense ingredients. One tablespoon of butter contains about 100 calories. Fat increases total calorie density even if the cake portion looks small.

Calories from Flour

Flour contributes carbohydrates and calories. While not as dense as fat, it still adds substantially to the total count.

Rhubarb Cake Calories by Recipe Type

Not all rhubarb cakes are equal in calories.

Classic Rhubarb Cake Calories

A simple butter-based recipe without topping contains:

• 220–300 calories per slice

This is usually the lowest-calorie traditional version.

Rhubarb Crumble Cake Calories

The crumble topping adds extra butter and sugar.

• 300–400 calories per slice

The topping alone can increase calories by 80–120 per serving.

Rhubarb Coffee Cake Calories

Often made with sour cream for moisture.

• 280–350 calories per slice

The added fat increases total energy.

Rhubarb Custard Cake Calories

With a custard layer:

• 320–420 calories per slice

The dairy and sugar in the custard raise calorie density.

Rhubarb Dump Cake Calories

Made with cake mix and butter:

• 350–450 calories per slice

This is typically the highest-calorie version.

Is Rhubarb Cake High in Calories?

Compared to other desserts:

• Chocolate cake: 350–500 calories per slice

• Carrot cake with frosting: 400–550 calories

• Banana bread: 250–350 calories

• Plain sponge cake: 200–250 calories

Rhubarb cake falls in the moderate range. It is lighter than heavily frosted cakes but higher in calories than fruit-based desserts without batter.

Can You Eat Rhubarb Cake While Losing Weight?

Yes, if it fits into your daily calorie target.

For example:

If your daily intake goal is 1,600 calories:

• A 250-calorie slice represents about 15% of your daily intake.

That can be reasonable if the rest of your meals are balanced and controlled.

Weight loss depends on total daily calories, not eliminating one specific dessert.

How to Reduce Rhubarb Cake Calories

If you want to enjoy rhubarb cake with fewer calories, consider these adjustments.

Reduce Sugar

Lower sugar by 20–30% without drastically changing texture. This reduces overall calories.

Replace Some Butter

Substitute part of the butter with:

• Unsweetened applesauce

• Plain Greek yogurt

This lowers fat calories while keeping moisture.

Skip the Streusel Topping

Removing crumble topping can reduce 80–120 calories per slice.

Cut Smaller Portions

Instead of cutting 8 slices, cut 12 or 16 smaller portions. You still enjoy the cake with fewer calories.

How to Calculate Homemade Rhubarb Cake Calories

To estimate rhubarb cake calories accurately:

1. Add up the calories of all ingredients.

2. Weigh the finished cake.

3. Divide total calories by total grams.

4. Multiply by the weight of your slice.

Using a kitchen scale provides the most accurate results.
