What Is a Whoopie Pie?
A whoopie pie is a chocolate cake sandwich made from two soft, pillowy chocolate cakes filled with a creamy center, traditionally made with marshmallow creme or buttercream.
Unlike cookie sandwiches, whoopie pies are:
- Soft and cakey
- Moist with a tender crumb
- Thick and fluffy rather than crisp
- Traditionally round and generous in size
They are often associated with Maine whoopie pies and Pennsylvania Dutch desserts, and the origin story varies by region. Some say Amish bakers added sweet filling between leftover cake batter rounds. Others believe the name came from children shouting “Whoopie!” when they found one in their lunchbox.
Why This Is the Best Whoopie Pie Recipe
There are dozens of variations online, but this version focuses on:
- Soft, fluffy texture
- Deep chocolate flavor
- Balanced sweetness
- Stable filling that doesn’t ooze
- Clear, beginner-friendly instructions
- Both cup and gram measurements
This recipe combines buttermilk for moisture retention, proper leavening balance, and controlled baking time to avoid dryness a common issue in many homemade whoopie pies.
Ingredients You’ll Need
Precision matters in baking. Below is a detailed ingredient table with U.S. and metric measurements.
Chocolate Cake Cookies
| Ingredient | US Measurement | Metric |
|---|---|---|
| All-purpose flour | 2 cups | 250g |
| Unsweetened cocoa powder (Dutch-process preferred) | ½ cup | 50g |
| Baking soda | 1 tsp | 5g |
| Salt | ½ tsp | 3g |
| Unsalted butter (room temperature) | ½ cup | 113g |
| Brown sugar | 1 cup | 200g |
| Egg | 1 large | — |
| Buttermilk | 1 cup | 240ml |
| Vanilla extract | 1 tsp | 5ml |
Classic Marshmallow Filling
| Ingredient | US Measurement | Metric |
|---|---|---|
| Marshmallow creme | 1 cup | 240g |
| Powdered sugar | 1 cup | 120g |
| Unsalted butter | ½ cup | 113g |
| Vanilla extract | 1 tsp | 5ml |
| Shortening (optional for stability) | ¼ cup | 50g |
Ingredient Substitutions & Pro Baking Notes
Understanding your ingredients improves results dramatically.
Buttermilk substitute: Mix 1 cup milk with 1 tablespoon vinegar. The acid reacts with baking soda, creating lift and tenderness.
Cocoa powder choice: Dutch-process cocoa produces deeper flavor and darker color. Natural cocoa yields lighter texture and more acidity.
Butter vs vegetable oil: Butter adds flavor. Oil increases moisture retention. Some bakers combine both.
Room temperature ingredients ensure proper creaming and smooth batter.
Step-by-Step Instructions
Step 1: Prepare the Batter
Preheat oven to 350°F (175°C) and line a parchment-lined baking sheet.
Cream butter and brown sugar until light and fluffy. This step incorporates air — crucial for structure. Add egg and vanilla extract. Mix until combined.
In a separate bowl, whisk flour, cocoa powder, baking soda, and salt. Alternate adding dry ingredients and buttermilk to the creamed mixture. Mix until just combined. Do not overmix overworking develops gluten and leads to dense cakes.
Step 2: Scoop and Shape
Use a cookie scoop to portion evenly. This ensures consistent baking.
Space 2 inches apart. The batter will spread slightly.
Step 3: Bake Perfectly
Bake 10–12 minutes. The tops should spring back when gently pressed. Avoid overbaking dryness is the most common mistake.
Cool completely before assembling.
Step 4: Make the Filling
Beat butter until smooth. Add powdered sugar gradually. Fold in marshmallow creme and vanilla. If needed, add shortening for stability.
The texture should be smooth, fluffy, and pipeable.
Step 5: Assemble
Pipe filling onto flat side of one cake. Top with another cake and gently press.
Let assembled whoopie pies rest 30 minutes to allow flavors to meld.
Baking Science Behind Perfect Whoopie Pies
Understanding the science separates average from bakery-quality.
- Buttermilk acid activates baking soda.
- Eggs provide structure and moisture.
- Proper creaming traps air for lift.
- Moisture retention depends on fat balance.
- Overbaking evaporates water content.
If your whoopie pies turn flat, it’s usually due to expired leavening agents or overly thin batter.
Common Mistakes & Fixes
Why are my whoopie pies flat?
Leavening may be inactive, or batter overmixed.
Why are they dry?
Overbaking or too much flour.
Why is my filling runny?
Butter too warm. Chill slightly and rewhip.
Why did they crack?
Oven temperature too high.

| Feature | Whoopie Pie | Cookie Sandwich |
|---|---|---|
| Texture | Soft, cakey | Often chewy |
| Structure | Cake batter | Cookie dough |
