What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and the fresh mint adds that special seasonal touch perfect for St. Patrick’s Day festivities.

• For the Chocolate Cake Layer:
  • 1 cup (125g) all-purpose flour
  • 1/2 cup (100g) granulated sugar
  • 1/4 cup (25g) unsweetened cocoa powder (I recommend Ghirardelli for rich flavor)
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/2 cup (120ml) buttermilk, room temperature (or milk with 1 tsp lemon juice)
  • 1/4 cup (60ml) vegetable oil
  • 1 large egg, room temperature
  • 1 tsp vanilla extract
  • 1/2 cup (120ml) hot water or brewed coffee (enhances chocolate flavor)
• For the Mint Frosting:
  • 1/2 cup (115g) unsalted butter, softened (use Land O’Lakes for best creaminess)
  • 2 cups (240g) powdered sugar, sifted
  • 2 tbsp heavy cream or milk (adjust for desired consistency)
  • 1 tsp peppermint extract (don’t overdo it—mint flavor should be fresh, not overpowering)
  • Green food coloring (optional, for that festive St. Paddy’s hue)
• For Garnish:
  • Mini chocolate chips or shaved chocolate
  • Fresh mint leaves (adds a pretty, fresh touch)

Substitution tips: Use almond flour for a gluten-free base (though texture will be denser), or swap heavy cream with coconut cream for a dairy-free option. If you prefer a natural green, matcha powder can replace food coloring, giving a subtle earthiness to the frosting.

Equipment Needed

• Mixing bowls (medium and large sizes)
• Measuring cups and spoons (for precise ingredient amounts)
• Whisk and spatula (for smooth batter and frosting)
• Electric hand mixer or stand mixer (makes frosting super fluffy, but you can whisk by hand if you’re feeling strong!)
• 8-inch square baking pan or round cake pan (for baking the chocolate cake layer)
• Cooling rack (allow cake to cool completely before assembling parfaits)
• Jars or clear dessert glasses (8 small mason jars or similar size containers work perfectly)

Personally, I like using a stand mixer for the frosting because it gets that dreamy texture with less arm work. If you’re on a budget, a good whisk and some muscle will do just fine. Just keep your butter softened—it really helps! Also, a serrated knife for cutting the cake into neat cubes makes assembly a breeze.

Preparation Method

1. Preheat and prepare: Preheat your oven to 350°F (175°C). Grease your 8-inch baking pan and line it with parchment paper for easy removal. This step keeps the cake from sticking and helps with a clean cut later. (10 minutes prep)
2. Mix dry ingredients: In a large bowl, sift together 1 cup all-purpose flour, 1/2 cup granulated sugar, 1/4 cup cocoa powder, 1 tsp baking powder, 1/2 tsp baking soda, and 1/4 tsp salt. This ensures no lumps and a smooth cake batter. (5 minutes)
3. Combine wet ingredients: In a separate bowl, whisk 1/2 cup buttermilk, 1/4 cup vegetable oil, 1 large egg, and 1 tsp vanilla extract until well blended.
4. Blend wet and dry: Pour the wet mixture into the dry ingredients and stir until just combined—don’t overmix! Batter will be thick but smooth. (2-3 minutes)
5. Add hot water: Slowly stir in 1/2 cup hot water or brewed coffee. The batter will thin out—this keeps the cake moist and rich. (1 minute)
6. Bake: Pour batter into the prepared pan and bake for 25-30 minutes or until a toothpick inserted comes out clean. The cake should spring back lightly when touched. (25-30 minutes)
7. Cool completely: Remove from oven and let the cake cool in the pan for 10 minutes, then transfer to a cooling rack. Patience here is key—warm cake will melt the frosting! (30-40 minutes)
8. Prepare frosting: Using a mixer, beat 1/2 cup softened butter until creamy. Gradually add 2 cups powdered sugar, alternating with 2 tbsp heavy cream. Add 1 tsp peppermint extract and a few drops of green food coloring if desired. Beat until light and fluffy. (10 minutes)
9. Assemble parfaits: Cut cooled cake into small cubes. In each jar, layer chocolate cake cubes, a generous spoonful of mint frosting, and repeat until jars are full, finishing with frosting on top. Garnish with mini chocolate chips and fresh mint leaves. (15-20 minutes)
10. Chill before serving: Refrigerate the parfaits for at least 1 hour to let flavors meld and frosting set. This step makes the mint taste pop and the texture just right. (1 hour)

Pro tip: If your frosting feels too stiff, add a splash more cream. If too soft, a bit more powdered sugar will fix it. And don’t rush the cooling process—warm cake + frosting = melty mess, trust me.

Cooking Tips & Techniques

One trick I learned early on is to always sift your cocoa powder and flour together. Clumps can ruin the smooth texture. Also, when mixing wet and dry ingredients, stir gently and stop as soon as combined—overmixing can make the cake tough, and nobody wants that.

For the frosting, softened butter is key. Too cold and you’ll struggle; too warm and you might end up with a greasy mess. I usually set butter out about an hour before starting or zap it in 5-second bursts in the microwave if in a rush.

Cutting the cake into uniform cubes helps with even layers and presentation. A serrated knife works best—just a gentle sawing motion. Also, layering the parfaits while the frosting is chilled helps keep it firm and neat.

Don’t skip the chilling step before serving! It not only helps the flavors marry but also firms up the frosting for the perfect spoonful. And if you want to multitask, bake the cake the night before and frost/assemble the next day. Makes for less stress on the big day.

Variations & Adaptations

• Dairy-Free Version: Use coconut oil in place of butter, almond milk instead of heavy cream, and a dairy-free chocolate cake mix or recipe.
• Adult Twist: Add a splash of Irish cream liqueur or crème de menthe to the frosting for a grown-up flavor kick perfect for St. Patrick’s Day parties.
• Berry Mint: Toss fresh raspberries or sliced strawberries between the layers for a fruity contrast that brightens the dessert.
• Gluten-Free: Use a gluten-free flour blend in the cake and double-check all other ingredients for gluten-free certification.
• Seasonal Swap: In summer, swap mint extract for fresh basil and add lemon zest to the frosting for a refreshing twist.

Personally, I tried the berry mint variation last summer, and it was a hit at a picnic. The berries added a burst of juicy freshness that balanced the richness beautifully. Feel free to experiment and make this dessert your own!

Serving & Storage Suggestions

Serve these Mint Chocolate Cake Jar Parfaits chilled, straight from the fridge. They look especially festive when garnished with a sprig of fresh mint and a few chocolate shavings on top. These parfaits pair wonderfully with a hot cup of coffee or a glass of cold milk—classic combos that never fail.

If you’re serving at a party, set them out on a decorated tray with little spoons for easy grabbing. They’re also perfect as individual gifts or party favors, wrapped with a ribbon around the jar neck.

Store leftovers covered in the refrigerator for up to 3 days. The flavors actually deepen after sitting overnight, so they’re great for making ahead. If you want to freeze them, do so before adding the frosting and thaw completely before layering and serving.

Reheat is not really recommended since the frosting will melt, but if you prefer a warm dessert, try spooning the cake and frosting into a bowl and microwaving for 10-15 seconds. Just enough to soften without melting completely.

Nutritional Information & Benefits

Each jar parfait contains approximately 350-400 calories, with a balance of carbs, fats, and a modest amount of protein. The use of real butter and fresh cream provides a satisfying richness, while the mint extract adds flavor with zero calories.

FAQs

Can I make these parfaits ahead of time?

Absolutely! You can bake the cake and prepare the frosting a day ahead. Assemble the parfaits a few hours before serving and keep them refrigerated.

What if I don’t have buttermilk?

No worries! Use regular milk and add 1 tsp of lemon juice or vinegar, let it sit for 5 minutes—this homemade buttermilk works just fine.

Can I use fresh mint instead of peppermint extract?

Fresh mint can be chopped and folded into the frosting, but the flavor will be milder. Peppermint extract gives a more pronounced mint flavor perfect for this recipe.

How long do these parfaits keep in the fridge?

They stay fresh for up to 3 days when covered properly. After that, the cake may start to dry out, so best enjoyed sooner.

Is it okay to use store-bought chocolate cake instead of baking from scratch?

Yes! Using a store-bought cake is a convenient shortcut. Just make sure it’s moist and pairs well with mint flavors for the best results.
