Quick Neapolitan Cake in a Jar

If you ask me, cake in a jar is one of the smartest dessert ideas out there.

This fun twist on the classic Neapolitan flavors gives you chocolate, vanilla, and strawberry all layered up in a cute mason jar. Each spoonful delivers that perfect trio of tastes that made the original ice cream so popular.

The layers stay nice and neat, making it easy to see all three flavors stacked on top of each other. Plus, the individual jars make serving a breeze – no cutting or messy plates needed.

It’s a crowd-pleasing dessert that’s perfect for parties or just when you want something sweet that looks a little fancy without all the fuss.

What Kind of Strawberries Should I Use?

Fresh strawberries are definitely the way to go for this recipe since they’ll give you the best flavor and texture in your layered dessert. Look for berries that are bright red, firm to the touch, and have that sweet strawberry smell – these will taste the best and hold up well when chopped. If fresh strawberries aren’t in season or available, you can use frozen ones, but make sure to thaw them completely and drain off any excess liquid before chopping. When preparing your strawberries, hull them and chop them into small, bite-sized pieces so they distribute evenly throughout the jar and are easy to eat with a spoon.

Options for Substitutions

This layered treat is pretty adaptable, so here are some easy swaps you can make:

• Digestive biscuits or graham cookies: Any crunchy cookie works here – try vanilla wafers, gingersnaps, or even crushed chocolate chip cookies. You’ll need about the same amount by weight.
• Dark chocolate: Milk chocolate or semi-sweet chocolate chips work fine if you prefer something sweeter. You can also use cocoa powder mixed with a bit of melted coconut oil.
• Coconut oil or nut butter: Regular butter works as a substitute, or try sunflower seed butter if you have nut allergies. Just make sure it’s at room temperature for easy mixing.
• Fazer Aito raspberry oat dessert: This specific product might be hard to find, so try any plant-based yogurt or pudding – raspberry, vanilla, or strawberry flavors work great.
• Fazer Aito Oat for whipping: Heavy cream, coconut cream, or any plant-based whipping cream will do the job. You might need to adjust the whipping time depending on what you use.
• Fresh strawberries: Frozen strawberries work too – just thaw and drain them first. You could also try raspberries, blueberries, or chopped peaches.

Watch Out for These Mistakes While Making

The biggest mistake when making layered desserts in jars is rushing the assembly process – each layer needs time to set properly, so chill your jars between adding the chocolate base and the raspberry layer to prevent them from mixing together.

Another common error is overpacking the digestive biscuit base, which can make it too dense and hard to eat with a spoon – gently press the mixture just enough to hold together.

Make sure your oat whipping cream is properly chilled before whipping, as warm ingredients won’t achieve the right consistency, and don’t skip chopping your strawberries into small, uniform pieces since large chunks can make the layers unstable.

For the best results, let your finished jars chill for at least 2 hours before serving, which allows all the flavors to meld together and makes the dessert much easier to enjoy.

What to Serve With Neapolitan Cake in a Jar?

These cute little cake jars are perfect as a standalone dessert, but they’re also great for serving at parties or picnics since they’re so portable. I love pairing them with a strong cup of coffee or espresso – the rich flavors really complement the sweet layers of chocolate, strawberry, and vanilla. If you’re hosting a dinner party, try serving them alongside some fresh berries or a light fruit salad to balance out the richness. For a fun twist, you can even add a dollop of whipped cream on top or sprinkle some crushed nuts for extra crunch.

Storage Instructions

Refrigerate: These cute little cake jars need to stay chilled in the fridge and will keep fresh for up to 3 days. Make sure to cover each jar with a lid or plastic wrap to prevent the whipped oat cream from absorbing other flavors. The layers actually taste even better after sitting overnight, so don’t worry about making them a day ahead!

Make Ahead: This dessert is perfect for preparing in advance since all the flavors meld together beautifully. You can assemble the jars up to 2 days before serving, just add the whipped oat cream right before you plan to eat them. The strawberries and raspberry layers will stay fresh and the chocolate base won’t get soggy.

Serve: Take your jars out of the fridge about 10 minutes before serving to let them come to the perfect temperature. The layers will be nicely set and easy to eat with a spoon. If you’ve stored them without the whipped cream, just whip up a fresh batch and dollop it on top right before enjoying.

Ingredients

For the cookie layer:

• 2 oz dark chocolate (70% cacao, finely chopped)
• 2 tbsp coconut oil (melted)
• Pinch salt
• 2.5 oz digestive biscuits (crushed into fine crumbs)
• 2 tbsp maple syrup

For the berry layer:

• 7 oz fresh strawberries (diced into 1/4-inch pieces)
• 2 containers (10.5 oz) Fazer Aito raspberry oat dessert

For the whipped oat topping:

• 2/3 cup Fazer Aito oat cream (chilled before whipping)
• 1.5 tsp vanilla sugar (or 1/2 tsp vanilla bean powder for more intense flavor)

Step 1: Prepare the Chocolate Biscuit Crumble Base

• 2.5 oz digestive biscuits
• 2 oz dark chocolate
• 2 tbsp coconut oil
• 2 tbsp maple syrup
• Pinch salt

Combine the crushed digestive biscuits, finely chopped dark chocolate, melted coconut oil, maple syrup, and salt in a bowl, mixing until the mixture resembles wet sand with visible chocolate pieces throughout.

This textured crumble will provide structural integrity and prevent the jar from becoming soggy.

Divide the mixture evenly among four jars, pressing it gently but firmly into the bottom of each to create a compact base layer about 1/2-inch thick.

Step 2: Layer the Raspberry and Strawberry Filling

• 2 containers Fazer Aito raspberry oat dessert
• 7 oz fresh strawberries

In a bowl, gently fold together the two containers of Fazer Aito raspberry oat dessert with the diced fresh strawberries, being careful not to crush the berries too much—you want some texture and visual appeal.

Spoon this mixture evenly over the crumble base in each jar, creating a generous middle layer that fills about half the remaining jar space.

I find that mixing the berries gently with a spatula rather than stirring keeps the fresh strawberry pieces distinct from the creamy raspberry dessert.

Step 3: Whip and Top with Vanilla Oat Cream

• 2/3 cup Fazer Aito oat cream
• 1.5 tsp vanilla sugar

Pour the chilled oat cream into a bowl and whip it with the vanilla sugar using an electric mixer or whisk until soft peaks form and the mixture becomes light and fluffy—this should take about 2-3 minutes with a mixer.

Transfer the whipped cream to a piping bag fitted with a decorative tip, then pipe it generously on top of the berry layer in each jar, creating attractive swirls.

I like to chill the assembled jars for at least 15 minutes before serving so the layers set and the flavors meld together beautifully.
