Ingredients
This recipe makes 16 generous squares.
For the Shortbread Base:
- 1 ½ cups (180g) all-purpose flour
- ½ cup (100g) granulated sugar
- ¼ teaspoon salt
- ¾ cup (170g) unsalted butter, softened
- 1 teaspoon pure vanilla extract
For the Raspberry Filling:
- 1 ½ cups (about 250g) fresh or frozen raspberries (do not thaw if frozen)
- ½ cup (150g) good quality raspberry jam or preserves
- 1 tablespoon cornstarch
- 1 tablespoon fresh lemon juice
For the Oat Streusel Topping:
- 1 cup (120g) all-purpose flour
- ¾ cup (60g) old-fashioned rolled oats
- ½ cup (100g) packed light brown sugar
- ½ teaspoon ground cinnamon
- ¼ teaspoon salt
- ½ cup (113g) unsalted butter, cold and cut into small pieces
Step-by-Step Instructions
-
Step 1: Get Ready to Bake!
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking pan. Line the pan with parchment paper, leaving an overhang on the longer sides. This will help you lift the baked squares out easily later.
Small tip: The parchment paper overhang is a game-changer for clean removal.
-
Step 2: Mix the Shortbread Base
In a medium bowl, combine the 1 ½ cups of flour, ½ cup of granulated sugar, and ¼ teaspoon of salt. Add the softened butter and vanilla extract. Use a fork, pastry blender, or your hands to mix until the ingredients come together and form a crumbly dough.
Small tip: Don’t overmix the dough. Just mix until no dry streaks of flour remain.
-
Step 3: Press the Base into the Pan
Press the shortbread dough evenly into the bottom of your prepared 9×13 inch baking pan. Use the back of a spoon or your fingers to make sure it’s flat and compact. Bake for 12-15 minutes, or until the edges are lightly golden.
Small tip: A flat-bottomed glass can help you get a really even and smooth crust.
-
Step 4: Prepare the Raspberry Filling
While the base is baking, combine the fresh or frozen raspberries, raspberry jam, cornstarch, and lemon juice in a small bowl. Stir gently until everything is well combined. The cornstarch will help thicken the filling as it bakes.
Small tip: If using frozen raspberries, there’s no need to thaw them first.
-
Step 5: Make the Oat Streusel Topping
In another medium bowl, combine the 1 cup of flour, rolled oats, brown sugar, cinnamon, and ¼ teaspoon of salt. Add the cold, cubed butter. Use a pastry blender or your fingertips to cut the butter into the dry ingredients until the mixture resembles coarse crumbs.
Small tip: Keep the butter cold for the best streusel texture. Warm butter will make it greasy.
-
Step 6: Assemble the Heavenly Squares
Once the shortbread base is lightly golden, carefully remove it from the oven. Spread the raspberry filling evenly over the warm base. Then, sprinkle the oat streusel topping generously over the raspberry layer.
Small tip: Spread the filling almost to the edges, but leave a tiny border so it doesn’t bubble over too much.
-
Step 7: Bake Until Golden
Return the pan to the oven and bake for another 20-25 minutes. The squares are ready when the streusel topping is golden brown and the filling is bubbly. Let the squares cool completely in the pan on a wire rack before cutting.
Small tip: Cooling completely is crucial! The filling needs to set, otherwise, the squares will be messy to cut.
-
Step 8: Cut and Serve
Once completely cool, use the parchment paper overhang to lift the entire slab of squares out of the pan. Place it on a cutting board. Use a sharp knife to cut into 16 squares. Enjoy your delicious Heavenly Squares!
Small tip: For cleaner cuts, wipe your knife with a damp cloth between each slice.
Tips & Variations
- Gluten-Free Option: Easily make these gluten-free by swapping the all-purpose flour for a 1:1 gluten-free baking flour blend that contains xanthan gum. Ensure your oats are certified gluten-free.
- Vegan Option: For a delicious vegan version, use a plant-based butter alternative (like Earth Balance sticks) for both the base and streusel. Ensure your raspberry jam is vegan (most are, but check for gelatin).
- Add More Fruit or Nuts: Feel free to mix in a handful of chopped walnuts or pecans into the streusel topping for extra crunch. You can also layer thinly sliced apples or peaches under the jam for a different fruit flavor.
- Spicy Version: For a warm, spiced twist, add ¼ teaspoon of ground ginger or a pinch of cardamom to the streusel topping. You could also use a jam infused with a hint of chili for a subtle kick.
- Different Fruit Fillings: Don’t limit yourself to raspberries! Try blueberry jam, apricot preserves, or even a mixed berry blend. A lemon curd filling would also be absolutely delightful.

Health Benefits
While these are a treat, Heavenly Squares do offer some goodness from their key ingredients!
Raspberries are little powerhouses of nutrition. They are packed with Vitamin C, which is fantastic for your immune system, and they contain antioxidants that help protect your body’s cells. Plus, they’re a good source of dietary fiber, which aids digestion and can help keep you feeling full.
Old-fashioned rolled oats, a star in our streusel, are a whole grain. This means they are rich in soluble fiber, especially beta-glucan, which is known for its potential to help lower cholesterol levels and support heart health. Oats also provide sustained energy, making them a great addition to any diet.
Even the butter, in moderation, contributes. It provides fat-soluble vitamins like A, E, and K2. These vitamins are essential for various bodily functions, including vision and bone health. The key is enjoying it as part of a balanced diet.
Lastly, the lemon juice in the filling adds a bright flavor and a little extra Vitamin C. It helps to balance the sweetness and brings out the natural tartness of the raspberries, making the squares even more enjoyable.
Serving Suggestions
- These Heavenly Squares are perfect on their own as a delightful snack or dessert with a cup of coffee or tea.
- Serve them slightly warm with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream for an extra special treat.
- They make an excellent addition to any brunch spread or potluck. Cut them into smaller bites for a party platter.
Storage Tips
Store leftover Heavenly Squares in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. They can also be frozen! Wrap individual squares tightly in plastic wrap, then place them in a freezer-safe bag or container for up to 2-3 months. To reheat, thaw at room temperature, then warm gently in the microwave for 15-20 seconds or in a preheated oven at 300°F (150°C) for 5-10 minutes until just warmed through.
