Preheat the oven to 180°C (350°F). Line two baking trays with parchment paper.
Sift together the flour, cocoa powder, baking powder, baking soda, and salt.
Beat the butter, caster sugar, and brown sugar for 3–4 minutes until pale and fluffy.
Beat in the eggs one at a time, then mix in the vanilla extract.
Mix half of the dry ingredients into the butter mixture. Add the milk and Greek yogurt, then fold in the remaining dry ingredients until just combined.
Use a 2-tablespoon cookie scoop to portion the batter onto the prepared baking trays, leaving about 5 cm between each portion.
Bake for 10–12 minutes or until the tops spring back lightly when touched. Do not overbake.
Cool on the tray for 5 minutes before transferring to a wire rack to cool completely.
Beat the butter until creamy. Gradually add the icing sugar, marshmallow fluff, vanilla, salt, and heavy cream if required. Beat until fluffy.
Pipe or spread about 2–3 tablespoons of filling onto one cake and sandwich with another cake of similar size.
Refrigerate the assembled Whoopie Pies for 15–20 minutes to allow the filling to set.
Serve with cold milk, coffee, hot chocolate, vanilla ice cream, fresh berries, chocolate sauce, caramel sauce, or whipped cream.

Whether you're baking for a special occasion, preparing desserts for a party, or simply craving a homemade chocolate treat, this foolproof Whoopie Pie recipe delivers soft, moist cakes and creamy filling that everyone will love.
Many Whoopie Pie recipes focus only on mixing and baking, leaving bakers to troubleshoot common problems on their own. This recipe goes a step further by explaining why each technique matters, helping you achieve soft, evenly baked cakes and a smooth, stable filling every time.
The chocolate cakes are made with carefully balanced ingredients that create a moist, tender crumb without becoming dry or crumbly. Chilling the batter before baking helps maintain a round, even shape, while using room-temperature ingredients ensures a smoother batter and more consistent baking.
You'll also learn how to prepare a fluffy vanilla filling that holds its shape without becoming overly sweet. This guide includes ingredient substitutions, storage recommendations, make-ahead tips, troubleshooting advice, and helpful baking notes, making it a complete resource rather than just another recipe.
Plain flour provides the structure for the cake-like cookies while keeping the texture soft and tender.
Good-quality cocoa powder delivers a deep chocolate flavour and rich colour. Natural cocoa creates a classic taste, while Dutch-process cocoa produces a darker, smoother finish.
Baking powder helps the cakes rise evenly, creating their signature light and fluffy texture.
A small amount of baking soda works with the cocoa to create a softer crumb and balanced flavour.
Salt enhances the chocolate flavour and balances the sweetness of the filling.
Butter adds richness, moisture, and a tender texture to both the cakes and the filling.
Caster sugar dissolves easily, creating a smooth batter and delicate crumb.
Room-temperature eggs provide structure while helping the cakes rise evenly.
Pure vanilla extract enhances both the chocolate cakes and the creamy filling.
Milk creates a smooth batter and keeps the cakes soft after baking.
Marshmallow fluff gives the filling its classic light, airy texture.
Icing sugar sweetens the filling while creating a smooth, pipeable consistency.
| Instead Of | Use |
|---|---|
| Plain flour | High-quality gluten-free baking blend |
| Whole milk | Oat milk, almond milk, or soy milk |

| Marshmallow fluff | Homemade marshmallow cream or vanilla buttercream |
| Caster sugar | Fine granulated sugar |
| Vanilla extract | Vanilla bean paste |
Natural cocoa has a brighter chocolate flavour with a slight acidity that works well with baking soda, producing soft, fluffy cakes.
Dutch-process cocoa has been treated to reduce acidity, resulting in a darker colour and smoother, richer chocolate flavour.
Both options work beautifully, although Dutch-process cocoa creates a deeper chocolate appearance.
Cream the butter and sugar until light and fluffy before adding the eggs and vanilla. Gradually mix in the dry ingredients and milk until a smooth batter forms.
Why this matters: Proper creaming incorporates air into the batter, creating lighter, softer cakes.
Scoop equal portions of batter onto lined baking trays, leaving space for spreading.
Why this matters: Even portions ensure all the cakes bake uniformly, making assembly much easier.
Bake until the cakes are puffed and spring back lightly when touched.
Why this matters: Proper baking keeps the cakes soft and moist without becoming dry.
Transfer the cakes to a wire rack and allow them to cool completely.
Why this matters: Filling warm cakes causes the cream to melt and slide out.
Beat the butter until creamy before mixing in the marshmallow fluff, icing sugar, and vanilla until smooth and fluffy.
Why this matters: Proper whipping creates a stable filling with a light, airy texture.
Pipe or spread the filling onto the flat side of one cake before gently topping it with another.
Why this matters: Even filling creates attractive, bakery-style Whoopie Pies with the perfect cake-to-cream ratio.
Flat Whoopie Pies are usually caused by overmixing the batter, expired leavening agents, or butter that was too warm. Measuring the ingredients accurately and chilling the batter if your kitchen is warm helps maintain their shape.
Yes. Bake the cakes a day in advance and store them in an airtight container. Assemble them with the filling before serving or refrigerate the assembled Whoopie Pies for up to 5 days.
Absolutely. Wrap each assembled Whoopie Pie individually and freeze for up to 3 months. Thaw overnight in the refrigerator before serving.
Classic vanilla marshmallow filling is the traditional choice, but cream cheese frosting, chocolate buttercream, peanut butter frosting, and cookies-and-cream filling are all delicious alternatives.
