Ingredients
(Tip: You’ll find the full list of Ingredients and measurements in the recipe card below.)
Cooking spray
All-purpose flour, for dusting the pans
1 box (15.25 oz) vanilla cake mix
Ingredients listed on the cake mix box (usually eggs, oil, and water)
1 container (16 oz) vanilla frosting
3 to 5 drops blue gel food coloring
1 store-bought cake donut, sliced in half
1 bag (10 oz) regular-sized marshmallows
1 cup mini marshmallows
1/2 cup crushed blue rock candy
2 tablespoons confectioners’ sugar
Directions
I begin by preheating the oven to 350°F and greasing an 8-inch round cake pan and an 8-inch ovenproof bowl with a rounded bottom. I dust both lightly with flour and tap out any excess.
I prepare the cake mix according to the package instructions. I pour slightly more than half of the batter into the bowl and the remaining batter into the round pan. I bake both, rotating them halfway through. The flat cake usually finishes after about 25 minutes, while the bowl cake needs about 10 additional minutes. Once baked, I turn both cakes out onto a wire rack and let them cool completely.
I mix the vanilla frosting with blue food coloring until I reach the shade I like. Using a serrated knife, I level the cakes. I frost the top and sides of the flat cake layer, then place the rounded cake on top with the flat side facing down. I frost the entire cake evenly.
To create the entrance, I attach one donut half to the bottom of the cake using frosting, then add the second half to extend the tunnel and cover it completely with frosting. I cut the large marshmallows in half lengthwise and press them into the frosting, starting from the bottom and working upward in neat rows. I cut the mini marshmallows in half and use them to decorate the entrance. I finish by adding crushed rock candy and a light dusting of confectioners’ sugar to resemble snow.
Servings And Timing
I usually get 8 to 10 servings from this cake. Preparation takes me about 25 minutes, and the total time, including baking and decorating, is around 1 hour. I find it perfect when I want a quick but impressive dessert.
Variations
I sometimes use white frosting for a classic snowy look instead of blue. When I want extra flavor, I switch to chocolate or funfetti cake mix. I also like adding shredded coconut for more texture or using silver or clear sprinkles in place of rock candy.
Storage/Reheating
I store this cake covered in the refrigerator for up to 3 days. Before serving, I let it sit at room temperature for about 15 to 20 minutes so the cake softens. I don’t reheat this cake, as it’s best enjoyed cool or at room temperature.
FAQs
Can I make this cake in advance?
I often bake the cake layers a day ahead and assemble and decorate the cake the next day.
What if I don’t have an ovenproof bowl?
I use any rounded, heat-safe bowl that fits comfortably in the oven.
Can I color the frosting a different shade?
I adjust the color however I like, depending on the theme or occasion.
Do the marshmallows get hard?
I find they stay soft for a couple of days when stored properly in the refrigerator.
Is this cake easy to decorate with kids?
I think it’s great for kids since placing marshmallows into frosting is simple and fun.
