Gather your supplies, preheat oven to 350 degrees

Generously grease a 13x9 pan

Line pan with marshmallows

Prep and rinse strawberries

Mash em up!

I discovered they're a bit easier to mash when you chop them into smaller pieces

All mashed!

Add jello mix. Stir it in and set strawberry mixture aside

Make cake batter according to directions.

Pour evenly over marshmallows

Spoon strawberry mixture evenly over cake batter

Like so. Put it in the oven

For 35-45 minutes. Don't over-bake! Mine took about 40 minutes.

It's done when a toothpick inserted in the center comes out clean 🍰 Let it cool and then invert the cake onto a platter.

Inverted! I didn't have a pretty platter so I used a cookie sheet. A note here: you should probably let it cool overnight in the fridge so the strawberry stuff has a chance to gel. I didn't. Oops!

Serve with whipped cream (I didn't have any on hand) and enjoy!
