Strawberry Bundt Cake starts out as another cake mix hack recipe but then is made even more delicious by adding a homemade marshmallow cream filling. Let me show you how to make this incredibly easy and delicious cake full of strawberry flavor!

If you've been a follower or reader of mine for any amount of time, you know that this site is all about EASY recipes. Cake mixes are something I use a lot in my baking. I've learned over the years how to doctor a cake mix to make it taste NOT like a cake mix...if that makes sense!
This cake is easily adapted to using a chocolate cake mix too!

How to make sure a cake doesn't stick to the pan:
When it comes to baking a cake, one of the most frustrating things can be having it stick to the pan. There are a few things you can do to help prevent this from happening:
- Make sure the pan is properly greased. You can use either butter or cooking spray, but make sure you get into all the corners and crevices.
- Dust the pan with flour or cocoa powder. This will create a barrier between the cake and the pan.
- Tap the pan on the counter a few times before adding the batter. This will help to remove any air bubbles that might be present.
- You can also line the pan with parchment paper like I do with my Pumpkin Bread Recipe.
- When you're ready to bake, make sure the oven is preheated to the correct temperature before adding the cake batter. Once the cake is baked, allow it to cool in the pan for a few minutes before turning it out onto a plate or wire rack.
- If the cake does stick to the pan, you can try running a thin knife around the edge of the cake.

Ingredients for the Cake:
- Strawberry Cake Mix, 15.25 ounce size
- Eggs
- Water
- Vegetable Oil
- Strawberry Jello , 3 ounce size box
Ingredients for the Marshmallow Filling:
- Butter
- Marshmallow Fluff
- Powdered Sugar
- Vanilla Extract
- Heavy Whipping Cream


Step-by-Step Directions
Step 1 | Combine the Cake Mix Ingredients
- In a large bowl, mix together the cake mix, eggs, water, vegetable oil and jello mix until well combined.

Step 2 | Baking Instructions
- Pour the batter into your prepared Bundt Cake Pan that's been sprayed with non-stick cooking spray. Lately, I really like to use Baker's Joy Baking Spray. However,Pam Cooking Spray recently came out with their version that I've used a few times. It works really well too!
- Bake for 35-40 minutes, until a toothpick comes out clean.
- Cool for 10 minutes and then turn the cake over onto a cooling rack until completely cooled.

Step 3 | Prepare the Marshmallow Cream Filling Ingredients
- In a large bowl, cream the butter until it’s light and fluffy. Add in the marshmallow fluff, powdered sugar and vanilla and mix until well combined.
- Slowly add in the heavy whipping cream and mix after each tablespoon. Stop adding the heavy cream once the consistency is creamy enough to be piped.

Step 4 | How to Fill Plastic Decorating Bags
Here’s an easy tip I’ve shared before on how to fill the plastic decorating bags:
- Take a large plastic storage bag or a disposable decorating bag, and place it inside a large drinking glass or tall jar.
- Cuff the excess bag over the sides of the glass.
- Make sure the inside of the bag is smooth by pressing it to the sides of the drinking glass.
- Spoon the batter into the bag using a spatula being careful not to fill it all the way up or the batter will overflow once you start squeezing.
- Gently lift the bag out of the glass jar and squeeze it gently to work the batter down into the bottom of the bag.
- Twist the end of the bag and snip one corner with the kitchen scissors.

Step 5 | How to Fill the Strawberry Bundt Cake
- Now comes the fun part! Let's fill the cake with the yummy marshmallow cream filling! You are not going to believe how EASY this step is!
- Carefully turn the bundt cake over on it’s top.
- Using a teaspoon, small cookie scoop or melon baller, scoop out 8-10 holes in the bottom of the cake.
- Then using the end of a wooden spoon, push the holes a little deeper and create a nice space for the cream to fill.
- Scoop the filling into a piping bag and fill each of the holes up with the cream filling.

Serving Tips
- To flip the cake back over, place your cake plate on top of the cake and carefully turn it back over.
- Dust with some powdered sugar, cut and enjoy!

I made this cake and my two kids loved it. My son wants it for his birthday cake so will make again. It is very good and turned out pretty even though it didn't last long.
Lois says
Best comment of the day! Thank you!!!
Anna Violette says
We used to make a similar cake in the 1980's. The filling was Marshmellow Fluff, mayo and cream cheese. You actually scooped out the ring and placed the filling on the inside. It was just an Angel food cake plain. Then you topped with cool whip and fresh strawberries. It was the best thing ever.
Lois says
That sounds yummy too!!! Thank you for visiting.

What a fun treat for Valentine’s Day! Pinned!

Thank you for pinning Amy!
Christine says
Does this need to be refrigerated?
Lois says
I think you can keep it out of the refrigerator for a few hours until you're ready to serve if you prepare it on the same day. You should refrigerate any leftovers.
Marisa F. Stewart says
What a pretty cake and the marshmallow filling is making me lick my lips. Our grandsons would love that cake - especially the ooey gooey part. I'm pinning to make it next weekend.
Jolina says
This looks soooo good! Sadly I don't see any strawberry cake mixes around here 🙁 Maybe it's a US thing? Or perhaps I haven't been looking hard enough... I've been waiting to make something with marshmallow fluff though. That thing's so good!
Elle says
I wanted to make this cake (again) but was out of strawberry cake mix. So, I ended up finding a from scratch strawberry cake recipe then I just added a little more of the strawberry jello mix than the strawberry cake recipe called for (but less extra jello mix in total than this recipe calls for. Just enough to get a stronger taste of the strawberry and jello) and it turned out beautifully.
Veena Azmanov says
Thanks for your detailed recipe. This cake looks so delicious and mouth melting and flavorful too.
