How to Make It
- Poke and Prepare:
- After baking a chocolate cake and letting it cool use the thick end of a wooden spoon or a sturdy skewer to poke holes all over the cake spaced about one to two inches apart this helps the fillings soak in
- Soak with Sweetness:
- Slowly pour sweetened condensed milk evenly across the entire cake letting it work its way down into every hole create a full layer so no dry spots remain
- Layer on Marshmallow:
- Gently scoop marshmallow fluff across the cake try to fill the holes and create a thick layer on the surface if the fluff is too stiff microwave it for a few seconds to help it spread
- Make the Chocolate Ganache:
- In a separate heat proof bowl heat heavy cream just to steaming then pour it right over the chocolate chips wait one minute then stir slowly from the center outward until fully glossy and smooth
- Finish with Ganache:
- Pour the warm ganache directly over the marshmallow layer spreading gently from the center out to the edges let it set for an extra shiny finish
- Chill Before Serving:
- Cover and refrigerate the cake at least a couple hours to allow the flavors to meld and the ganache to firm up cut with a thin sharp knife for clean slices
Watching the marshmallow fluff melt into the cake always brings me joy and that sweet chocolate ganache brings out smiles in everyone when I serve this at family gatherings.
Flavor Boosters
You can use regular mini marshmallows melted with a spoonful of butter as a swap for marshmallow fluff. Dairy free chocolate chips and vegan condensed milk are perfect if you need a lactose free version. Sprinkle in some instant espresso powder to the ganache for extra depth if you love mocha flavors.
Serving Suggestions
Serve each square on its own or top with fresh raspberries and a dollop of whipped cream. For birthday parties try fun confetti sprinkles across the top before the ganache sets. Slice cold for clean layers or warm individual pieces for a gooey dessert.
Creative Twists
This recipe has roots in classic American poke cakes which became popular for their inventive use of canned dairy products. Around the holidays add crushed peppermint or a dash of cinnamon to the ganache for a festive twist. It works beautifully for both summer picnics and cozy winter nights.
Every time I bring this cake to a potluck people ask for the recipe and are delighted to find out how simple it is. My niece always calls it the marshmallow magic cake and it has starred in two birthday parties already.
