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 a few fresh additions give the cake its signature mint chip vibe.

• For the Cake Layers:
  • All-purpose flour (2 ½ cups / 310g) – I recommend King Arthur for best texture
  • Granulated sugar (1 ¾ cups / 350g)
  • Unsalted butter (¾ cup / 170g), softened (adds richness)
  • Large eggs (3), room temperature
  • Buttermilk (1 cup / 240ml), room temperature (helps keep cake moist)
  • Baking powder (2 ½ tsp)
  • Baking soda (½ tsp)
  • Salt (½ tsp)
  • Pure vanilla extract (1 ½ tsp)
  • Mint extract (½ tsp) – adjust to taste for that signature mint flavor
• For the Mint Chip Pudding Filling:
  • Whole milk (3 cups / 720ml)
  • Instant vanilla pudding mix (2 packages, 3.4 oz each)
  • Mint extract (¼ tsp)
  • Mini chocolate chips (¾ cup / 135g) – Ghirardelli works great here
  • Heavy cream (1 cup / 240ml), whipped to soft peaks
• For the Mint-Infused Simple Syrup:
  • Granulated sugar (½ cup / 100g)
  • Water (½ cup / 120ml)
  • Fresh mint leaves (a small handful, optional for extra freshness)
• For the Frosting:
  • Heavy cream (2 cups / 480ml), chilled
  • Powdered sugar (¼ cup / 30g)
  • Mint extract (¼ tsp)
  • Mini chocolate chips or shaved chocolate for garnish (optional)

If you need a gluten-free option, you can swap the all-purpose flour with a gluten-free baking blend, but I’d recommend testing first as texture varies. For a dairy-free twist, use coconut milk and a dairy-free pudding mix. Fresh mint leaves can be muddled into the simple syrup for a brighter note, especially in summer.

Equipment Needed

• Two 9-inch (23 cm) round cake pans – non-stick or well-greased
• Mixing bowls (medium and large)
• Electric mixer or stand mixer – a must for whipping cream and making the pudding smooth
• Measuring cups and spoons – for precise measurements
• Rubber spatula – perfect for folding in chocolate chips gently
• Whisk – for mixing dry ingredients and simple syrup
• Saucepan – to prepare the mint-infused simple syrup
• Cake stand or plate for assembling and serving

If you don’t have a stand mixer, a hand mixer works just fine. For budget-friendly cake pans, lightweight aluminum pans are great and heat evenly. After baking, to keep your pans performing well, I recommend seasoning them occasionally with a bit of oil and wiping clean (avoid harsh scrubbing). This recipe’s success partly depends on smooth, whipped cream, so if you’re new to whipping cream, an electric mixer really saves time and effort.

Preparation Method

1. Preheat your oven to 350°F (175°C). Grease and flour the two 9-inch cake pans or line with parchment paper. This helps the cake release easily once baked.
2. Make the cake batter: In a large bowl, cream the softened butter (¾ cup / 170g) and granulated sugar (1 ¾ cups / 350g) together using an electric mixer until light and fluffy—about 3-4 minutes. This step is key for a tender crumb.
3. Add eggs one at a time: Beat in 3 large eggs, one by one, mixing well after each addition. Stir in the vanilla extract (1 ½ tsp) and mint extract (½ tsp) gently.
4. Combine dry ingredients: In a separate bowl, sift together the flour (2 ½ cups / 310g), baking powder (2 ½ tsp), baking soda (½ tsp), and salt (½ tsp). Sifting helps keep the cake light.
5. Alternate adding dry ingredients and buttermilk: Add the dry ingredients to the butter mixture in three parts, alternating with the buttermilk (1 cup / 240ml). Start and end with the dry ingredients. Mix gently after each addition to avoid overworking the batter.
6. Divide the batter: Evenly pour the batter into the two prepared cake pans. Smooth the tops with a spatula for even layers.
7. Bake: Place pans in the oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Rotate pans halfway through baking for even color.
8. While the cakes bake, prepare the mint-infused simple syrup: In a small saucepan, combine ½ cup sugar and ½ cup water. Add fresh mint leaves if using. Bring to a gentle boil and stir until sugar dissolves. Remove from heat and let cool. Strain out mint leaves before using.
9. Prepare the pudding filling: In a large bowl, whisk together the instant pudding mixes with 3 cups cold whole milk until thickened (about 2 minutes). Stir in ¼ tsp mint extract and fold in ¾ cup mini chocolate chips gently. Chill the pudding for at least 15 minutes.
10. Whip the cream for filling: Using a chilled bowl and beaters, whip 1 cup heavy cream to soft peaks. Fold the whipped cream into the pudding mixture carefully to keep it light and airy.
11. Cool the cake layers: Once baked, let cakes cool in the pans for 10 minutes, then turn out onto wire racks to cool completely.
12. Assemble the cake: Place one cake layer on your cake stand. Brush generously with the mint-infused simple syrup to add moisture and flavor. Spread half the pudding filling evenly over the layer.
13. Top with the second cake layer: Again, brush with syrup and spread the remaining pudding filling on top. Chill in the fridge for 20 minutes to set.
14. Prepare the frosting: Whip 2 cups cold heavy cream with ¼ cup powdered sugar and ¼ tsp mint extract until stiff peaks form.
15. Frost the cake: Spread the whipped cream frosting evenly over the top and sides of the cake. Garnish with mini chocolate chips or shaved chocolate if you like.
16. Chill before serving: Refrigerate the cake for at least 1 hour for the layers to meld together beautifully.

Cooking Tips & Techniques

Here’s some honest advice I’ve picked up making this cake over the years. First, don’t rush the creaming of butter and sugar—it really makes a difference in cake texture. If you skip this step or do it quickly, your layers might turn out dense or dry.

When mixing the batter, always alternate dry ingredients with buttermilk and mix gently. Overmixing will develop gluten and make the cake tough, which we definitely don’t want here.

Whipping cream can be tricky if your bowl or cream isn’t cold enough. I always chill both in the fridge for at least 15 minutes before whipping. It helps the cream reach perfect peaks fast without turning grainy or separating.

Don’t forget to brush the layers with that mint-infused simple syrup—it’s the secret weapon for moist, flavorful cake. Skip it, and you might end up with dry layers, especially if you’re making the cake ahead of time.

Finally, folding the chocolate chips into the pudding gently is key to keeping the filling light. If you stir too vigorously, you’ll lose that fluffy texture everyone loves.

Variations & Adaptations

Want to switch things up? Here are a few tasty variations I’ve tried and loved:

• Vegan version: Use a dairy-free chocolate pudding mix, almond milk, and coconut cream instead of heavy cream. Use flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg) in the cake batter.
• Chocolate mint twist: Add ¼ cup cocoa powder to the cake batter for a chocolate layer that pairs beautifully with the mint pudding.
• Fruit addition: Fold in chopped fresh strawberries or raspberries into the pudding filling for a fruity surprise that brightens the mint flavor.
• Gluten-free option: Substitute all-purpose flour with a gluten-free baking blend. I recommend Bob’s Red Mill 1-to-1 gluten-free flour for the best results.
• Alternate mint flavors: Swap mint extract for peppermint extract for a cooler kick, or use fresh mint leaves finely chopped in the pudding for a more herbal note.

One personal favorite is the chocolate mint twist—my husband can’t get enough of it! It’s a great way to add a richer dimension without complicating the process.

Serving & Storage Suggestions

This cake is best served chilled or at cool room temperature. The mint chip pudding filling is luscious and refreshing when cold, especially on a warm spring day. For presentation, a simple dusting of cocoa powder or a few fresh mint leaves on top adds a lovely touch.

It pairs wonderfully with a cup of hot coffee or a minty herbal tea to balance the sweetness. For a St. Patrick’s Day party, serve alongside some shamrock-shaped sugar cookies or a light fruit salad.

Store leftover cake covered tightly in the refrigerator for up to 4 days. The flavors actually deepen after a day, which makes it even better the next day. If you want to freeze it, wrap the cake tightly with plastic wrap and aluminum foil, and freeze for up to 2 months. Thaw overnight in the fridge before serving.

To reheat (if you prefer it slightly warmer), remove any frosting garnish and microwave a slice for 15-20 seconds—just enough to soften the filling without melting it.

FAQs

What can I use instead of instant pudding mix?

You can make homemade pudding using cornstarch, sugar, milk, and vanilla, but instant pudding mix saves time and gives a consistent texture. If you want a natural option, try making a custard-style pudding and chill until thickened.

Can I make this cake ahead of time?

Absolutely! It tastes even better the next day once the flavors meld. Just assemble and refrigerate overnight. Bring it to room temperature before serving for the best texture.

How do I prevent the cake layers from drying out?

Brushing the layers with the mint-infused simple syrup is essential. It locks in moisture and adds extra flavor, keeping the cake tender and delicious.

Can I freeze the assembled cake?

Yes, but be sure to wrap it tightly in plastic wrap and foil to prevent freezer burn. Thaw in the refrigerator overnight before serving.

What’s the best way to get mini chocolate chips evenly distributed in the pudding?

Fold them in gently at the very end with a rubber spatula to avoid breaking or melting the chips. This keeps the texture perfect and the chocolate chips intact.
