Substitutions + Alternatives

Can I use All-Purpose Flour?

Yes. If you don’t need gluten-free, swap in all-purpose flour using the same amount listed in the ingredients.

Can I use regular dairy?

Absolutely. The recipe works with dairy milk or dairy yogurt if preferred. Almond milk tends to be thinner, so choose a milk or milk alternative with a fuller texture for best results.

How To Make Homemade Little Debbie Cupcakes

  1. Preparation: Preheat the oven to 350°F (175°C). Spray muffin pans with nonstick baking spray.
  2. Mix batter: In a mixing bowl beat eggs and sugar until fluffy. Add vanilla, yogurt, oil, and espresso powder and mix until combined. Add the dry ingredients gradually and stir in the coffee until just incorporated.
  3. Bake: Divide the batter among the muffin cups and bake for 35–45 minutes, or until a toothpick inserted in the center comes out clean. Let the cupcakes cool completely.
  4. Make the filling: Beat butter and powdered sugar until smooth, then fold in marshmallow fluff until evenly combined. Hollow a small center from each cooled cupcake (about 1/2″ diameter) and pipe or spoon the filling inside.
  5. Make the ganache: Heat heavy cream and pour over chopped dark chocolate in a heatproof bowl. Let sit a minute, then stir until smooth. Dip the top of each filled cupcake into the ganache and let it set.

Variations & Substitutions

  • Use different flavored yogurts for a subtle change in the cupcake batter.
  • Swap to white chocolate ganache for a sweeter, lighter topping.

Commonly Asked Questions

Can I use instant coffee instead of brewed coffee?

Yes. Dissolve instant coffee in hot water before adding it to the batter to get the same depth of flavor.

How should I store leftover cupcakes?

Store cupcakes in an airtight container at room temperature for 3–4 days. For longer storage, freeze them in airtight containers or bags for 2–3 months and thaw in the refrigerator overnight.

How do I get the classic marshmallow swirl on top?

Fill a piping bag fitted with a large round tip with marshmallow cream or frosting. Hold the bag perpendicular to the cupcake and apply steady pressure while swirling from the center outward.

Can I replace vegetable oil with another oil?

Yes — canola oil or melted coconut oil work well. Note that the flavor and texture may change slightly depending on the oil chosen.

What can I use instead of marshmallow cream?

Substitute marshmallow fluff, a homemade marshmallow sauce, or a simple buttercream made with powdered sugar, butter, and vanilla for a similar sweet filling.
