This Irish Blackberry Fool has become my family's favorite summer dessert when blackberries are at their peak. The contrast between tangy cream and sweet berries creates a dessert that feels both light and indulgent at the same time.
I first made this for a summer gathering when I needed something impressive but quick. The oohs and aahs when I brought out these beautiful layered desserts convinced me to keep this recipe in regular rotation. Now my children request it whenever they spot blackberries at the market.
Ingredients
- Fresh blackberries: The star of the show. Look for plump, deeply colored berries without any mold or mushiness. Wild blackberries work beautifully if you can find them.
- Grand Marnier: Adds a subtle orange complexity that elevates the berries. You can omit for an alcohol-free version.
- Fresh lemon juice: Balances the sweetness with bright acidity. Always use fresh rather than bottled for the best flavor.
- Granulated sugar: Helps create the berry syrup without overwhelming the natural tartness.
- Unflavored gelatin: Provides stability to the cream layer so it holds its shape. A small amount ensures it remains light rather than rubbery.
- Heavy cream: Choose high-quality cream with at least 36% fat content for the richest texture.
- Powdered sugar: Dissolves easily in the cream layer without any grittiness.
- Vanilla bean paste: Offers more intense vanilla flavor than extract with lovely specks throughout the cream.
- Greek yogurt: Adds tanginess that balances the richness of the cream. Use full-fat for the creamiest result.
Step-by-Step Instructions
- Create the blackberry syrup:
- Combine berries, Grand Marnier, lemon juice and sugar in a saucepan. Heat gently, allowing the berries to soften and release their juices. A slow simmer for 8-10 minutes is perfect. You want the berries to maintain some shape while creating a luxurious syrup. Allow to cool completely before assembling.
- Prepare the gelatin:
- Sprinkle the gelatin over cold water in a small bowl and let it bloom for a minute until it absorbs the liquid. A quick 15-second microwave melts it completely. Set aside but do not let it cool completely or it will set.
- Whip the cream:
- Beat the heavy cream until it starts to thicken, then add the melted gelatin mixture, powdered sugar, and vanilla. Continue whipping until soft peaks form. The cream should hold its shape but still have a silky, flowing quality.
- Combine with yogurt:
- Gently fold the whipped cream into the Greek yogurt using a large spatula. Use a down-and-up motion rather than stirring to maintain as much air as possible in the mixture.
- Layer the dessert:
- Start with a portion of berry syrup in each glass, followed by a layer of the cream mixture. Repeat the layers, finishing with a dramatic swirl of berry syrup on top. The transparent glasses showcase the beautiful contrast between the deep purple berries and white cream.

You Must Know
The vanilla bean paste is my secret weapon in this recipe. While vanilla extract works perfectly well, the paste provides those beautiful tiny black specks throughout the cream layer that signal to guests that this is something special. I discovered this ingredient years ago and now use it in nearly all my baking.
Make It Your Own
This recipe welcomes adaptations based on what berries look best at the market. Raspberries work beautifully with a shorter cooking time, while blueberries may need an extra minute or two to break down properly. Strawberries create a gorgeous pink version perfect for Valentine's Day or baby showers.
The Irish Connection
Traditional Irish fools date back centuries and originally featured gooseberries folded into sweetened cream. The name likely comes from the French word "fouler" meaning to crush or press. Blackberries grow wild throughout the Irish countryside, making this version particularly authentic to the landscape. In autumn, Irish families still gather for blackberry picking expeditions along country lanes.
Serving Suggestions
Serve this fool in clear glasses to showcase the beautiful layers. Small mason jars create a rustic presentation, while champagne flutes elevate it for special occasions. Shortbread cookies make the perfect accompaniment, providing a buttery, crunchy contrast to the creamy dessert.
Storage Tips
The assembled dessert keeps beautifully in the refrigerator for up to two days, making it perfect for advance preparation. The gelatin stabilizes the cream layer, preventing it from weeping or separating. Cover each glass with plastic wrap to prevent any refrigerator odors from affecting the delicate flavors.
