The Ultimate Dutch Letter Bars A Simplified Sinterklaas Treat
The iconic Dutch Letter, or Banketstaaf, is a cherished Dutch pastry, traditionally enjoyed during the Sinterklaas season. With its delicate, flaky almond paste filling encased in crisp, buttery puff pastry, it’s a festive delicacy. However, crafting the individual letters can be a time-consuming labor of love. Enter the Dutch Letter Bar: all the beloved flavors of the classic, reimagined into an easy, shareable, and utterly irresistible bar cookie form. Imagine a buttery, shortbread-like crust, a layer of rich, marzipan-sweet almond filling, and a final crumble of delicate pastry on top. It delivers that perfect contrast of textures and the unmistakable flavor of almonds in every bite. This recipe is designed for the home baker who craves the authentic taste without the intricate shaping, making it a perfect year-round treat for cookie exchanges, holiday trays, or a special afternoon coffee. This guide will walk you through creating these unforgettable bars, capturing the essence of a Dutch bakery in a simple, foolproof pan.
The Magic of the Dutch Letter Bar: Tradition Made Simple
The genius of the bar format lies in its deconstruction of the classic components. Instead of wrestling with rolling and folding puff pastry, we create a tender, press-in crust that mimics the pastry’s richness and provides a sturdy base. The heart of the treat—the almond paste filling—is lovingly preserved. We blend real almond paste with sugar, egg, and a hint of citrus to create a layer that bakes up firm yet moist, with a deep, authentic almond flavor that is neither too sweet nor too gritty. A final sprinkling of reserved crust mixture on top bakes into a delicate, crumbly topping that adds textural interest and visual appeal. This method guarantees consistent results, easy slicing, and the ability to make a large batch at once. It’s the perfect solution for bringing a taste of Dutch tradition to your table with minimal fuss and maximum reward.
Gathering Your Ingredients for Authentic Flavor
The flavor profile here is all about quality almonds and butter. Sourcing good almond paste is key.
For the Crust & Topping:
· All-Purpose Flour: The structure for our buttery crust.
· Granulated Sugar: Sweetens the crust and helps it crisp.
· Butter: Use cold, unsalted butter for the best flavor and texture. It’s cut into the flour to create a tender, shortbread-like base.
· Salt & Almond Extract: Salt balances the sweetness, while a touch of almond extract reinforces the nutty theme.
For the Almond Filling:
· Almond Paste: This is the non-negotiable star. Do not substitute with marzipan, which is much sweeter and softer. Look for a brand with a high almond content (often found in a tube or can in the baking aisle).
· Granulated Sugar: Sweetens the dense almond paste.
· Egg: Binds the filling, giving it structure as it bakes.
· Lemon Zest or Juice: A tiny bit of citrus brightens the rich almond flavor and is a traditional addition, cutting through the sweetness perfectly.
Your Complete Ingredient List & Tools
Ingredients:
For the Crust & Crumble Topping:
· 2 ½ cups (312g) all-purpose flour

· 1 cup (2 sticks / 226g) cold unsalted butter, cubed
· ½ teaspoon pure almond extract
For the Almond Filling:
· 1 (7-ounce) tube or can (about 200g) almond paste
· ⅓ cup (67g) granulated sugar
· 1 large egg
· 1 teaspoon fresh lemon zest OR ½ teaspoon lemon juice
· ¼ teaspoon pure almond extract
For Finishing (Optional):
· 1 tablespoon coarse sparkling sugar or sliced almonds

Essential Equipment:
· 9×13 inch metal baking pan
· Parchment paper
· Food processor (or pastry cutter and mixing bowls)
· Medium mixing bowl
· Hand mixer
Step-by-Step Instructions for Foolproof Bars
Step 1: Prep the Pan and Oven
Preheat your oven to 350°F (175°C). Line your 9×13 inch baking pan with parchment paper, leaving an overhang on the two long sides. This “sling” will allow you to lift the entire slab out for clean, easy slicing. Lightly grease any exposed parts of the pan.
Step 2: Make the Crust & Crumble Mixture
In the bowl of a food processor, combine the flour, sugar, and salt. Pulse briefly to mix. Add the cold, cubed butter and almond extract. Pulse in short bursts until the mixture resembles coarse, sandy crumbs with some pea-sized pieces of butter remaining. Do not process into a uniform dough. If you don’t have a food processor, use a pastry cutter or two forks in a large bowl.
Transfer about 1 ½ cups of this crumb mixture to a small bowl and set aside for the topping.
Step 3: Press in the Crust
Pour the remaining crumb mixture into your prepared pan. Press it down firmly and evenly into a compact layer using your fingers, the bottom of a measuring cup, or a flat glass. This pressed layer is your crust. Bake in the preheated oven for 15 minutes. The crust should look dry and just barely beginning to color at the edges. Remove from the oven and let it cool slightly while you prepare the filling. Leave the oven on.
Step 4: Prepare the Authentic Almond Filling
Break the almond paste into small pieces and place it in a medium mixing bowl. Add the sugar, egg, lemon zest (or juice), and almond extract. Using a hand mixer (this is much easier than doing it by hand), beat the mixture on medium speed for 1-2 minutes until it is thoroughly combined and smooth. It will be thick and pasty.
Step 5: Assemble the Bars
Spread the almond filling evenly over the warm, par-baked crust. This is easiest done by dolloping spoonfuls across the crust and then carefully smoothing it into a thin, even layer with an offset spatula or the back of a spoon.
Sprinkle the reserved 1 ½ cups of crumb mixture evenly over the top of the almond filling. Do not press it down. For extra sparkle and crunch, sprinkle with coarse sugar or a few sliced almonds.
Step 6: Bake to Golden Perfection
Bake for 25-30 minutes, or until the crumble topping is a light golden brown and the almond filling appears set (it may puff slightly).
Step 6: The Crucial Cooling Phase
This is vital for clean slicing. Place the pan on a wire rack and allow the bars to cool completely in the pan—this will take at least 2 hours. The almond filling needs time to firm up as it cools.
Step 7: Slice and Serve
Once completely cool, use the parchment paper sling to lift the entire slab onto a cutting board. Using a sharp knife, slice into squares or bars. For a festive finish, dust lightly with powdered sugar just before serving.
Serving Suggestions & Tips for Mastery
· The Perfect Pairing: These bars are sublime with a cup of strong coffee, black tea, or a glass of cold milk.
· Storage: Store cooled bars in an airtight container at room temperature for up to 4 days. They can also be frozen for up to 3 months.
· Almond Paste is Key: Using true almond paste (not marzipan) is essential for the correct flavor and texture. Marzipan will make the filling too sweet and soft.
· Butter Temperature: Ensure your butter is cold for the crust. This guarantees a flaky, tender texture rather than a greasy, dense one.
· Flavor Variations: Add ½ teaspoon of cinnamon to the crumb mixture for a warm spice note, or fold a handful of finely chopped toasted almonds into the almond filling for extra crunch.
