Introduction

This Twinkie Bundt Cake is a fun and nostalgic twist on a classic yellow cake, filled with creamy marshmallow frosting. It’s easy to prepare and perfect for sharing at any gathering or just as a delightful homemade treat.

A small round slice of yellow sponge cake with a soft, fluffy texture is shown on a white plate with a brown rim. The cake has one layer with a thick white creamy filling in the center. Next to the cake slice on the plate is a silver fork. In the background, there are more slices of the same cake on white plates with brown rims, two white bottles, a white vase with pampas grass, and a beige cloth napkin, all set on a white marbled surface.

Ingredients

1 box yellow cake mix
3 eggs
1 cup water
1/2 cup cooking oil
1 cup Pillsbury Fluffy Frost Vanilla Marshmallow Frosting (or homemade marshmallow frosting, see notes)
Baking spray (contains flour) or grease and flour for pan
Powdered sugar (optional, for dusting)

Instructions

Step 1: Preheat your oven to 350ºF.
Step 2: Prepare the cake batter by mixing the yellow cake mix, eggs, water, and cooking oil on medium speed until just slightly lumpy.
Step 3: Coat a bundt pan with baking spray or grease and lightly dust with flour to prevent sticking. Pour the batter into the prepared pan.
Step 4: Bake the cake for 25 to 35 minutes. Start checking when the top firms; insert a toothpick into the center and remove the cake from the oven as soon as it comes out clean.
Step 5: Allow the cake to cool completely in the pan.
Step 6: Once cooled, keep the cake in the pan and poke holes about 1 1/2 inches apart by inserting your finger nearly to the bottom of the pan and moving side to side to widen each cavity.
Step 7: Fill a sandwich bag with marshmallow frosting, cut a small pea-sized hole in a corner, and pipe the frosting into each hole, pushing the tip deep for full filling.
Step 8: Loosen the sides of the cake gently with a spatula or butter knife. Place a plate or cake stand upside down on top of the pan, then flip both to release the cake onto the plate carefully.
Step 9: Optionally, dust the cake with powdered sugar before serving for a festive touch.

Tips & Variations

For a homemade marshmallow frosting, combine marshmallow fluff with a bit of softened butter and vanilla extract for a fresher flavor.
If you don’t have a bundt pan, a tube pan or a regular round cake pan can work, but baking times may vary.
Try adding a teaspoon of lemon zest to the batter for a subtle citrus twist that complements the marshmallow filling.

Storage

Store the cake covered at room temperature for up to 2 days to keep it fresh. For longer storage, wrap carefully and refrigerate for up to 5 days. When ready to serve, allow refrigerated cake to come to room temperature. Avoid freezing as the marshmallow filling may change texture.

How to Serve

A round bundt cake with a golden brown crust sits on a white plate. The cake has a smooth, slightly shiny texture with gentle ridges running from the center hole to the edges. It is lightly dusted with white powdered sugar, creating a soft contrast on the top and some around the base. The background is a white marbled surface that adds a clean and simple look to the scene. photo taken with an iphone --ar 4:5 --v 7

Can I use a different cake mix flavor?

Ingredients

Scale

For the Cake

1 box yellow cake mix
3 large eggs
1 cup water
1/2 cup cooking oil
Baking spray (with flour) or grease and flour for bundt pan

For the Filling

1 cup Pillsbury Fluffy Frost Vanilla Marshmallow Frosting (or homemade marshmallow frosting)

For Garnish

Powdered sugar (optional)

Instructions

Preheat Oven: Preheat your oven to 350ºF (175ºC) to prepare for baking the cake.
Prepare Cake Batter: Using an electric mixer on medium speed, combine the yellow cake mix, eggs, water, and cooking oil. Mix until the batter is just slightly lumpy to avoid overmixing, which keeps the cake tender.
Grease Bundt Pan: Coat a bundt pan generously with baking spray that contains flour, or alternatively grease the pan and lightly dust with flour to ensure the cake releases easily after baking.
Pour and Bake: Pour the prepared batter into the bundt pan and bake in the preheated oven for 25 to 35 minutes. The baking time may vary depending on your pan; start checking at 25 minutes. Insert a toothpick into the center—when it comes out clean, the cake is done.
Cool Cake: Allow the cake to cool completely in the pan on a wire rack before proceeding to the filling step.
Create Filling Holes: Once cooled, keep the cake in the pan and use your finger to poke holes almost all the way to the bottom of the cake (which is the top in the pan). Move your finger side to side to expand each hole. Space holes approximately 1 1/2 inches apart.
Fill with Frosting: Transfer the marshmallow frosting into a sandwich bag and seal. Cut a small pea-sized hole at one corner of the bag’s tip. Insert the tip into each hole and gently squeeze to fill the cavities with frosting, ensuring the frosting is deep inside each hole.
Remove Cake from Pan: Loosen the sides of the cake gently with a small rubber spatula or butter knife without cutting into the cake. Place a flat plate or cake stand inverted over the bundt pan, then flip both together to release the cake. Lift the pan carefully, ensuring the cake lands evenly on the plate.
Garnish: Optionally sprinkle the top of the cake with powdered sugar for a pretty, festive finish.

Notes

For best results, ensure the cake is completely cool before poking holes to prevent crumbling.
If homemade marshmallow frosting is preferred, you can make it by whipping together marshmallow fluff and softened butter until fluffy.
Use a small tip on the piping bag for easier and cleaner filling of frosting into holes.
This cake pairs wonderfully with a cup of coffee or tea for afternoon treats.
Store leftovers covered at room temperature for 2 days or refrigerated for up to 4 days.
