How Many Calories Are In A Slice Of Pumpkin Roll? | Quick Calorie Guide

What Counts As A Slice

A pumpkin roll is a thin sponge cake wrapped around a sweet filling. Most bakery trays and supermarket rolls cut it into 8–12 rounds. A typical round weighs about 75–85 grams. That’s the sweet spot most labels use, and it lines up with common retail items.

Weight matters. A thin round lands closer to 280 calories. A thicker round or a roll with extra filling pushes toward 350 calories. That’s why two slices that look alike can differ by more than 70 calories.

Estimated Calories By Slice Size And Filling

The table below shows practical ranges that match common retail labels and home bakes. Use it to sanity-check your plate at a glance.

Slice Profile	Approx. Weight	Estimated Calories
Thin Round, Light Swirl	~70–75 g	~260–290 kcal
Standard Round, Cream Cheese	~78–85 g	~300–330 kcal
Thick Cut Or Extra Filling	~90–110 g	~340–430 kcal

Calories In Pumpkin Roll Per Slice — Sizes And Fillings

Real labels tell the story. A supermarket tray lists 1 slice (73 g) at 320 calories for a pumpkin cake roll with cream cheese filling. Another national brand shows 1/8 cake (78 g) at 280 calories. A seasonal roll lists 3 oz (85 g) at 307 calories, and a large bakery roll posts 85 g at 350 calories. These examples land squarely in the 280–350 range most people see at the table.

If you don’t have a label, a simple rule helps: sponge-style snack cakes with a creme center average about 106 calories per ounce. That’s a USDA average for creme-filled cake. Multiply by your slice weight to get a close estimate. A 3-ounce round lands near 318 calories. A 2.6-ounce round comes in around 276 calories. Labels vary, but this method tracks well.

Why The Count Changes

Cake Thickness

A thicker sheet holds more batter per spiral. That adds grams and calories fast. Even a 10 g bump can add roughly 36 calories when the cake runs near 360 kcal per 100 g on average across retail labels.

Filling Style

Cream cheese brings fat calories. Buttercream tilts even richer gram-for-gram. Lean fillings or lighter swirls shave calories. For a quick reference on the fat load in the swirl, see a standard cream-cheese entry such as cream cheese nutrition (per spoonful), then scale to how much ends up in the roll.

Toppings And Finishes

Powdered sugar dust adds a little. A caramel drizzle or nut crust adds more. These are small per bite but they stack up across a party plate.

How To Estimate Without A Label

Grab a kitchen scale if you have one. Weigh the slice in grams. Multiply by 3.6–4.0 kcal per gram to get a quick range. That range mirrors branded rolls that average around 359–360 kcal per 100 g.

1. Weigh the slice. Say it’s 82 g.
2. Multiply 82 × 3.7 = 303 kcal (middle of the range).
3. Add 10–30 kcal if there’s extra frosting or a caramel finish.

This quick math keeps you within a few bites of the label on most bakery rolls.

What About The Pumpkin Itself?

The puree isn’t the calorie driver. Pumpkin brings fiber and potassium with modest energy. Government tables list canned pumpkin at a low energy density compared with sugary fillings and cake. You’ll feel the calories more from flour, sugar, and the swirl than from the orange part. For a nutrient snapshot of pumpkin’s minerals, see the Dietary Guidelines list of potassium sources, which includes canned pumpkin by portion size.

Brand Examples At A Glance

Here are real-world labels you may run into during the fall baking rush. Serving sizes vary; check your package for the exact cut.

Product	Serving Size	Calories
Marketside Pumpkin Cake Roll	1/8 cake (78 g)	280 kcal
H-E-B Pumpkin Cake Rolls (Tray)	1 slice (73 g)	320 kcal
Libby’s Pumpkin Roll	3 oz (85 g)	307 kcal
The Father’s Table Pumpkin Roll	1 slice (85 g)	350 kcal

Macros You Can Expect

Most slices skew carb-heavy with a moderate hit of fat and a small amount of protein. A standard 78–85 g round often falls near 35–40 g carbs, 11–16 g fat, and 2–4 g protein. Sugar lands around the mid-20s in grams on many labels. Salt runs a couple of hundred milligrams per slice. The exact mix depends on the recipe, the swirl, and any toppings.

How To Fit A Slice Into Your Day

Pick Your Spot

Pair the dessert with a protein-rich meal so you’re not hungry again right away. Rotating a lighter lunch or a longer walk can balance the day without fuss.

Choose The Cut

Go thin when you want the taste without the full calorie load. Split a thick round with a friend. Or save half for later. Your appetite and your plan call the shots.

Tweak The Recipe (If You Bake)

• Use a lighter swirl. Neufchâtel lowers fat grams versus full-fat cream cheese.
• Keep the dusting modest. Powdered sugar caps the look with fewer extra calories than a heavy glaze.
• Cut 10 slices instead of 8. Smaller rounds make portions easier at parties.

When Labels And Averages Don’t Match

Recipes vary. A home bake with a generous swirl can overshoot the averages by a chunk. A leaner filling or a careful cut can undershoot. That’s normal. When you can, lean on weight and the 106-per-ounce rule for better estimates than eyeballing. It’s fast and surprisingly close to retail data.

Bottom Line For Dessert Lovers

You’re looking at roughly 300 calories for a standard round. If you want a smaller hit, go thin or pick the lightest swirl on the tray. If you’re saving room for a rich dinner, the thicker round makes more sense. Either way, plan the rest of the day around it.
