This homemade giant Twinkie bundt cake is easy to whip up using cake mix. This marshmallow frosting filled golden bundt cake will rock your world. Rave reviews every time!
Prepare cake batter. Using a mixer on medium speed, blend together cake mix, eggs, water and cooking oil until just slightly lumpy.
Pour batter into a bundt pan coated with BAKING spray (contains flour) or grease and sprinkle lightly with flour.
Bake for 25-35 minutes. Cook time varies by pan so when the top of the cake starts to firm up, insert a toothpick into the middle of the cake, as soon as it comes out clean, remove the cake.
Cool cake. Let bundt cake cool completely.
Poke hole for filling. Once the cake is cooled, leave it in the pan and poke the cake almost all the way to the bottom of the pan (which will be the top of the cake). Move your finger from side to side to widen the cavity and allow more frosting. Keep poking making your holes about 1 ½" apart.
Add frosting. Fill a sandwich bag with marshmallow frosting and cut one of the corner tips of the bag to create a pea-sized hole. Seal the bag then squeeze the bag to dispense the marshmallow frosting into each hole. Tip: Put the tip of the bag as far into each hole as you can get so plenty of frosting gets into each poked hole.
Remove cake from bundt pan. Using a tiny rubber spatula or butter knife, separate the sides of the cake from the bundt pan as best you can without cutting into the cake. Once the cake is nice and loose, place a flat plate or cake stand upside down on top of the bundt cake pan. Then gently turn both the bundt pan and cake pan over and let gravity do its thing. Carefully and slowly lift away the bundt pan while you peak around all sides to see if the cake dropped evenly onto the plate.
Add powdered sugar. Top with sprinkled powdered sugar for a festive look.

Notes
To easily remove your bundt cake from your bundt pan, be sure to grease using baking spray. This help prevent the cake from cracking.If your cake does crack though, just add a little extra powdered sugar to the top!Be sure not to overcook or cake will become dry. It will be nice and moist if you cook it just until it sets!To speed up cooling, you can put the cake in the freezer for 30 minutes. (Note: Make sure you let the cake cool completely or the marshmallow filling will melt and be absorbed into the cake after you add it.)
