Prepare the Cake: If using a homemade angel food cake, ensure it’s completely cooled before assembling.

Prepare the Strawberry Mixture: In a large bowl, mash the diced strawberries with a fork to release juice.

Make the Cream Mixture: Gently fold the Cool Whip and mini marshmallows into the mashed strawberries.

Chill the Mixture: Cover the bowl and refrigerate for 20 minutes to thicken.

Prepare the Cake Layers: While the cream chills, cut the angel food cake horizontally into three even layers.

Assemble the Cake: Spread a portion of the cream mixture on the bottom layer of the cake, then top with the middle layer. Repeat with the cream mixture and the top layer.

Finish Assembly: Cover the entire cake with the remaining cream mixture.

Chill: Refrigerate for at least 90 minutes to allow the flavors to meld and the cake to firm up.

Decorate & Serve: Optionally, decorate with fresh sliced strawberries before serving.
