Gourmet Low-FODMAP Raspberry Frangipane Bars with White Chocolate Drizzle; Gluten-free

The British Baking Show became a part of my routine during the Coronavirus quarantine.  With the lockdown and lack of new television for many months, I was able to watch the first nine seasons. It was a great distraction…every time I watched the show, I wanted to make that recipe.

Above all, I was yearning for frangipane. The amount of times they featured this dessert, and my passion for everything ‘almond’ (see some of my other almond recipes listed below) resulted in my absolute NEED to bake this.  This recipe has been a while coming!!

Nevertheless, I wouldn’t settle for a mediocre frangipane.  I wanted the recipe to be foolproof and amazing.

I didn’t want a tart with a complicated edge, or a pie that could be difficult to slice and serve. I wanted a simpler approach, while still GOURMET enough for a fancy party. A tray bake was the answer!

Tip: If you want to make this recipe in a tart shell instead, it will work the same 🙂

You are going to swoon over these low-FODMAP Frangipane bars.  Studded with raspberries, drizzled with white chocolate and topped with toasted almonds, they are, as Mary Berry says, ‘sheer perfection’.

Although I do like Prue, Mary Berry is just soooo classy.

And, if you like to add your almonds and white chocolate directly to the actual frangipane dough, that would work great too 🙂

These low-FODMAP Raspberry Frangipane bars have a rich, buttery and crumbly crust, with a sweet and gorgeous frangipane top. And they are GLUTEN-FREE!

Directions

Prepare crust:

• Preheat oven to 350 F. Grease 8 inch square pan with vegetable shortening and line with parchment paper
• Combine low-FODMAP flour, sugar, xanthan gum and salt in mixer bowl or food processor (I used processor)
• Add butter and mix on low speed until crumbly (pulse for food processor)
• Add vanilla and mix well. You will need to use your hands a bit to form it.
• Press immediately in prepared pan using your hands or the bottom of a glass
• Bake for about 15-20 minutes until set and lightly golden
• Set on a rack to cool while you prepare the remaining ingredients

Prepare Frangipane:

• In a stand mixer, or using an electric hand mixer, cream the butter and sugar on medium-high until fluffy (about 2 minutes)
• Add in the eggs and extracts and continue mixing on medium-high, scraping bowl as necessary
• Slowly add the almond meal, then low-FODMAP flour and salt with mixer on low speed, stopping to scrape down bowl as needed
• Turn mixture to high and beat until well combined
• Once mixture is completely smooth, pour/spread it on top of your prepared low-FODMAP crust layer
• Arrange the raspberries over the frangipane and press in slightly
• Bake for 35-40 minutes until puffed and lightly golden, and the center is just set
• Let cool in pan on a wire rack until room temperature
• When cooled, melt your white chocolate in a double boiler, or microwave using 30 second bursts, until runny and smooth and drizzle over the cooled bars
• Sprinkle with confectioner’s sugar and toasted almonds
• Slice and serve, may also be refrigerated for 3-5 days
