This Weight Watchers-friendly whoopie pie recipe makes about 12 soft, chocolatey sandwich cookies with just three main ingredients: devil’s-food cake mix, plain pumpkin purée, and fat-free whipped topping. The batter needs no eggs, oil, or water from the cake-mix instructions, and the cookies bake in only 10–12 minutes per tray.
The finished pies are tender, moist, and pleasantly pumpkin-smooth beneath their rich chocolate flavor. With 15 minutes of preparation, 15–20 minutes for cooling and assembly, and a total time of about 40–45 minutes, this simple dessert is an easy way to enjoy a portion-friendly treat.

There is something wonderfully nostalgic about a whoopie pie: two tender chocolate cakes wrapped around a cloudlike filling. This lighter version keeps the fun, handheld shape while replacing a traditional rich filling with fat-free whipped topping.
The cake rounds have a soft, almost brownie-like bite from the pumpkin purée. Pumpkin adds moisture without making the cookies taste strongly of pumpkin, so the chocolate remains the leading flavor.
This recipe is also wonderfully practical for busy bakers. You only need to stir together two ingredients for the cookies, scoop the batter, bake, cool, and assemble.

Ingredients You’ll Need
Keep the ingredient list exactly as written for the most reliable texture. The pumpkin replaces the extra liquid and fat normally used with boxed cake mix, creating a thick batter that can be scooped into rounds.
- One box devil’s-food cake mix: Choose a package measuring about 15–16 ounces.
- One 15-ounce can plain pumpkin purée: Look for pumpkin labeled purée, not pumpkin pie filling.
- One 8-ounce tub fat-free whipped topping: A product such as Cool Whip Free works well for the filling.
Do not add eggs, oil, or water, even if those ingredients appear in the regular cake directions. They are not part of this two-ingredient cookie method.
For a dessert-table spread, pair these chocolate pies with a fruity option such as this easy pineapple pie. The cool, tropical flavor makes a pleasant contrast to the cocoa-rich whoopie pies.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F. Line one or more baking sheets with parchment paper or silicone mats, which helps the soft cookies release cleanly and keeps cleanup easy.
Step 2: Add the dry devil’s-food cake mix and the entire can of plain pumpkin purée to a large mixing bowl. Stir with a sturdy spoon or spatula until no dry pockets remain and the batter looks evenly blended.
Step 3: Scoop rounded tablespoons of batter onto the prepared sheets, leaving room between portions for spreading. For the most consistent results, use a small cookie scoop and aim for 24 equal cookie rounds.
Step 4: Bake the rounds for 10–12 minutes per tray. The tops should look set and spring back lightly when touched, but avoid overbaking because the cookies are best when soft.
Step 5: Let the cookies cool on the baking sheet for a short time if they seem delicate, then transfer them to a wire rack. Cool them completely before adding the topping; even slightly warm cookies can cause the whipped topping to soften and slide.
Step 6: Turn half of the cooled rounds flat-side up. Spread or pipe fat-free whipped topping over those cookies, keeping the filling slightly away from the edge so it stays contained when the sandwich is closed.
Step 7: Place the remaining rounds on top, flat side down, and press very gently. Refrigerate the finished whoopie pies briefly before serving for a tidier bite and a firmer filling.
Chef Tips for Soft, Even Whoopie Pies
Plain pumpkin purée is essential. Pumpkin pie filling already contains sugar and spices, and it changes both the flavor and the consistency of the batter.
Use a cookie scoop when possible. Equal rounds make it easier to divide the recipe into about 12 finished pies, which is helpful when tracking servings and WW Points.
If the batter seems thick, resist the urge to add water or oil. The mixture is supposed to be scoopable and dense, and adding extra liquid can make the cookies spread unpredictably.
Check the first tray at the 10-minute mark because ovens vary. The cookies should be set on top but still tender in the center rather than dry or crisp.
For a polished bakery look, pipe the whipped topping in a spiral using a pastry bag or a zip-top bag with the corner snipped off. A simple spoon-spread filling tastes just as good and keeps the recipe wonderfully uncomplicated.
For another family-friendly dessert with a playful presentation, consider serving these alongside a banana split pie. The two desserts offer different textures while both remaining easy to portion.
WW-Friendly Serving and Point Notes
Exact WW Points are not universal for this recipe. They depend on the brand and size of the cake mix, the whipped topping label, the number of finished pies, and the current Weight Watchers plan.
For the clearest tracking, make 24 equal cookie rounds and assemble 12 sandwiches. Weighing or dividing the batter evenly can help when you want each serving to be as consistent as possible.
Reduced-sugar or sugar-free devil’s-food cake mix may be used in some versions, but package sizes and baking results differ by brand. If you make a substitution, check the package instructions and calculate the recipe using the specific labels.
These whoopie pies are satisfying because the portion is self-contained: one soft chocolate sandwich provides a defined serving instead of leaving you to cut a large cake or pie. Serve one chilled with coffee, tea, or a glass of cold milk.
Storage and Make-Ahead Advice
Store assembled whoopie pies covered in the refrigerator. Chilling keeps the fat-free whipped topping firm and helps the sandwiches hold their shape.
They are especially convenient for making ahead because the cookie rounds can cool while you prepare the rest of a meal. Assemble them once the cookies are completely cool, then refrigerate before dessert time.
Keep the cookies protected from dry refrigerator air by using an airtight container or tightly covering the plate. Place parchment between layers if you need to stack them.
For a jam-inspired dessert idea to serve another day, try this strawberry rhubarb jam with toast, yogurt, or a simple biscuit. Its tangy fruit flavor is a lovely counterpoint to these chocolate treats.
Easy Dessert Menu Pairings
Whoopie pies are naturally casual, so they fit everything from a children’s party to a relaxed family dinner. Arrange them on a chilled platter with the chocolate sides facing up so the white filling creates an appealing contrast.
For a dessert table, offer fresh berries or sliced bananas nearby. Their natural freshness balances the soft cake and adds color without requiring another complicated recipe.
If you are planning a complete comfort-food menu, keep the main course equally approachable with these 30-minute stuffed shells. Finish with chilled whoopie pies for a meal that feels special without demanding hours in the kitchen.

Ingredients
Method
- Heat the oven to 350°F and line baking sheets with parchment paper or silicone baking mats.
- Stir the dry devil’s-food cake mix and plain pumpkin purée together in a large bowl until the batter is smooth. Do not add the eggs, oil, or water listed on the cake-mix box.
- Drop rounded tablespoons of batter onto the prepared baking sheets, leaving space between portions. A small cookie scoop helps make 24 equal rounds for consistent serving sizes.
- Bake for 10–12 minutes per tray, until the tops look set and spring back lightly when touched.
- Cool the cake rounds completely on a wire rack. They should be fully cool before filling so the whipped topping does not melt.
- Spread or pipe fat-free whipped topping onto the flat side of half the rounds. Place the remaining rounds on top and gently press to form sandwiches.
- Refrigerate the assembled whoopie pies briefly before serving. Store leftovers covered in the refrigerator.
Notes
Final Thoughts
This Weight Watchers-friendly whoopie pie recipe proves that a homemade dessert can be simple, soft, and genuinely satisfying. The two-ingredient pumpkin cake rounds come together quickly, while fat-free whipped topping creates a light, creamy center.
Remember the three details that make the biggest difference: use plain pumpkin purée, skip the extra cake-mix ingredients, and cool the cookies completely before assembly. Those steps protect the texture and keep the sandwiches neat.
Because brands and WW plans change, calculate the current Points value from your own labels and serving count. Then make 24 equal rounds, assemble about 12 pies, refrigerate them briefly, and enjoy a chocolate dessert with an easy portion built right in.
