Grasshopper (mint chocolate) Cake

Grasshopper Cake

One of my favorite yearly birthday cakes!

Every year for my dad’s birthday - and sometimes also for Father’s Day - my mom makes a ‘Grasshopper cake.’ It's a classic for our family - no one ever gets tired of it! 

"What is a Grasshopper cake?"

Fair question! In short, it’s a cake-take on the Grasshopper cocktail. The Grasshopper is typically made with Creme de Menthe, Creme de Cacao, and heavy cream. (I'll be honest - we made one and tried it once. It was good...but the cake is so much better!) 

My mom's cake recipe calls for a white cake mix, with  ½ cup of the water replaced with Creme de Menthe. Doesn’t sound like much, but I tried more than this once, and the mint was so strong it was almost bitter. Lesson learned!

I also think using buttermilk instead of water and butter instead of oil gives the cake a richer more bakery-like texture without changing the flavor. I’ve used chocolate ganache instead of the chocolate fudge the recipe calls for. It keeps the same texture and rich chocolate flavor, and is a bit easier to work with. 

You can absolutely frost this cake with buttercream / cream cheese frosting if you'd prefer. But I love using stabilized whipped cream to decorate since it’s light, tastes amazing, and captures the classic flavors of the cake I grew up with!
Give it a shot and let me know how it goes!! 

"I don't know about the square cake thing...can I make this cake with round pans?" 

Absolutely! Round layers may be just a touch thicker and might need a minute or two more baking time, but you can use the same recipe with 8-inch round pans!

I used a square pans with a square acrylic cake disc in the video/photos. I won't lie; although I love the look of square cakes, they can be just a bit more difficult to frost. But since most of the decorating can be done with a piping bag, this is a great option if you'd like to try your first square cake! 

"I don't know about using cake mixes. Is there a scratch recipe you can recommend?" 

Yep! This Grasshopper Ombre Cake recipe uses scratch layers flavored with Creme de Menthe like this recipe. You can ignore the food coloring directions; just transfer batter to pans and bake!

Ingredients

Grasshopper Cake layers

  • 2 boxes white cake mix (I like Duncan Hines)
  • 1 cup unsalted butter (or 2 sticks, melted)
  • 1 1/2 cups buttermilk (room temperature)
  • 1/2 cup Crème de Menthe liqueur
  • 8 egg whites (or 1 cup egg whites from a carton)

Chocolate ganache (for filling + decorating)

Stabilized Whipped Cream:

  • 2 cups heavy whipping cream
  • ½ cup water (combine with gelatin)
  • 2 teaspoons powdered gelatin
  • ¾ - 1 cup powdered sugar
  • 2-4 Tablespoons Creme de Menthe liqueur to taste
  • 3-4 drops liquid green food coloring

Decorations

Instructions

Grasshopper Cake layers

  • Preheat oven to 350°F. Prepare three 8-inch round pans with baker's floured spray (or grease and line with parchment rounds).
  • Combine melted butter, buttermilk, Crème de Menthe, and egg whites in a bowl, and blend in packaged cake mixes. Scrape down the sides of the bowl with a spatula, and beat for about 2 minutes, until well blended.
  • Divide batter evenly between the prepared cake pans (I find a kitchen scale helpful for this part). This guarantees your layers will bake to be the same height. Spread batter evenly to pan edges and bake for time specified on box; mine took about 25 minutes. Allow cake layers to cool for 10-15 minutes on a wire cooling rack before removing from pans. Cool completely before frosting. Set in the fridge or freezer to accelerate the cooling process if desired. (This is a great time to make your ganache and whipped cream!)

Chocolate ganache

  • Combine chocolate chips and whipping cream in a microwave-safe bowl. Microwave in 20-second intervals on half power; stirring in between until fully melted and smooth.
  • Chill until thick enough to spread, but it'll be the easiest to work with if you don't let it solidify completely.

Stabilized Whipped Cream

  • Chill your mixing bowl and beaters/mixer attachment for 15 minutes before whipping cream.
  • Place water in a microwave-safe bowl and sprinkle powdered gelatin over the top; allow to sit for 5 minutes to soften. Microwave in 30-second intervals until melted and allow to cool; gelatin must be liquid but not hot when added to the whipping cream.
  • Add whipping cream, powdered sugar, and Crème de Menthe to mixing bowl; beat on medium-high speed just until beater marks begin to show distinctly (about 1 minute in my stand mixer). Add gelatin mixture to cream, pouring in a steady stream while beating constantly. (Try to avoid pouring directly on the beater so it doesn’t splatter). Beat until stiff peaks form. Place in the refrigerator until ready to use.

Assembly

  • Once your cakes are cool, level them (if needed). Place a smear of chocolate on your square (to keep the cake from sliding while you decorate it) and center your first cake layer in the center of the circle. Pipe a border of whipped cream or frosting around the outer edge of the layer, and fill with chocolate ganache. Add a sprinkle of chopped Andes mints, and place the next layer on top. Repeat the process with your remaining cake layers.
  • Now you're ready to crumb-coat . If you're unfamiliar with crumb-coating, it's just what it sounds like – spreading a thin layer of whipped cream over the entire outside of the cake to keep crumbs out of your final layer. I usually do this with my large offset spatula.
  • Once your crumb coat has set (this takes about 5-10 minutes in the fridge), add your final layer of frosting and smooth. I like to use an offset spatula and bench scraper for this part.

Now the fun part – decorating!

  • Transfer your whipped cream or frosting to a large piping bag, and your remaining chocolate fudge or chocolate ganache to another piping bag (I used a large bag + star tip for my whipped cream and a smaller bag + Wilton 1M tip for my chocolate). Pipe in rosettes, swirls, squiggles, or whatever shapes you’d like until the cake is covered! I covered mine with halved Andes mints for a bit more texture.
  • (Note: using my favorite Cream Cheese Buttercream Frosting – replacing the vanilla with Creme de Menthe – is also an option!)
