Maple Donut Bars
Maple Donut Bars combine classic maple donut flavor in an easy, shareable bar format.
Ingredients
For the Donut Bars:
- 2 ½ cups (300g) all-purpose flour, sifted
- 1 ½ cups (300g) granulated sugar
- 2 teaspoons (10g) baking powder
- ½ teaspoon (3g) salt
- ¾ cup (170g) unsalted butter, softened
- 2 large eggs, at room temperature
- 1 cup (240ml) whole milk, at room temperature
- 2 teaspoons (10ml) vanilla extract
- 1 teaspoon (5ml) maple extract
For the Maple Glaze:
- 3 cups (360g) powdered sugar, sifted
- ½ cup (120ml) pure maple syrup
- ¼ cup (60ml) whole milk or heavy cream
- ½ teaspoon (2.5ml) vanilla extract
- ⅛ teaspoon salt
For Garnish (Optional):
- ¼ cup (30g) chopped toasted pecans or walnuts
Instructions
- Preheat oven to 350°F (175°C). Grease and flour a 9×13 inch (23×33 cm) baking pan.
- In a large mixing bowl, whisk sifted all-purpose flour, granulated sugar, baking powder, and salt for 1-2 minutes until no lumps remain.
- In a separate medium bowl, or using a stand mixer with a paddle attachment, cream softened unsalted butter and granulated sugar on medium speed for 3-4 minutes until light in color and fluffy.
- Beat in 2 large eggs one at a time, mixing 45 seconds after each. Mix in vanilla extract and maple extract until just combined. Scrape bowl sides.
- Add dry mixture in three alternating additions with whole milk in two portions. Begin and end with dry mixture. Mix on low speed for 20-30 seconds after each addition until just combined, with no flour streaks.
- Pour batter into the greased, floured 9×13 inch (23×33 cm) baking pan. Spread evenly with an offset spatula.
- Bake for 25-28 minutes at 350°F (175°C). Bars are done when a wooden skewer inserted into the center comes out clean and edges are golden brown.
- Remove pan from oven; transfer to a wire rack. Cool in pan for 45-60 minutes until completely cool.
- In a medium bowl, whisk sifted powdered sugar, pure maple syrup, ¼ cup (60ml) whole milk or heavy cream, vanilla extract, and ⅛ teaspoon salt for 2-3 minutes until smooth and pourable. If too thick, add milk 1 tsp at a time. If too thin, add powdered sugar 1 tbsp at a time.
- Once bars are cool, pour prepared maple glaze over top. Spread evenly with an offset spatula.
- If using garnish, sprinkle ¼ cup (30g) chopped toasted pecans or walnuts over wet glaze immediately.
- Let glazed bars sit 15-20 minutes at room temperature until glaze sets and is firm. Slice into 16 squares.
Notes
- Browning Butter: For deeper flavor, brown the unsalted butter: Melt butter in a saucepan over medium heat, swirling until golden brown and nutty (5-7 minutes). Cool slightly before adding to batter.
- Sifting Dry Ingredients: Sift all-purpose flour and powdered sugar. This removes lumps, aerates ingredients, and ensures a smoother batter and a lump-free glaze.
- Proper Cooling: Glaze only completely cool bars. Applying glaze to warm bars causes melting and an inconsistent coating.
- Storage Recommendations: Store Maple Donut Bars in an airtight container at room temperature for up to 3 days. Refrigerate for up to 5 days; bring to room temperature before serving.
- Freezing Instructions: Freeze unglazed donut bars, wrapped tightly in plastic wrap then aluminum foil, for up to 3 months. Thaw at room temperature, then glaze and serve.
Pro Tips for Perfect Maple Donut Bars
Ingredient Tips
- Substitute cake flour for all-purpose:For a noticeably softer, more delicate crumb in your bars, replace 1 cup of all-purpose flour with 7/8 cup (14 tablespoons) cake flour plus 2 tablespoons cornstarch. This specific ratio creates a significantly lighter texture by reducing gluten formation.
- Soften butter to 68-70°F (20-21°C):Leave butter on the counter for 30-45 minutes until it yields slightly when pressed, but still holds its shape. This temperature is crucial for proper creaming with sugar, ensuring an even emulsion and preventing a dense, greasy bar base.
- Use Grade A Dark Robust Maple Syrup for glaze:Opt for Grade A Dark Robust maple syrup (formerly Grade B) for the strongest, most authentic maple flavor. Its deeper, richer notes will stand up to the sweetness of the powdered sugar, preventing a bland or overly sweet glaze.
- Warm 2 tablespoons of whole milk or heavy cream for the glaze:Gently heat the milk or cream to 90-100°F (32-38°C) before adding it to the powdered sugar and maple syrup mixture. This helps create a smoother, lump-free glaze that slides off the spoon easily, ensuring an even and professional-looking coating.
- Sift 2 cups of powdered sugar before mixing glaze:Pass powdered sugar through a fine-mesh sieve twice to remove any lingering lumps. This guarantees a silky-smooth glaze that coats evenly and dries without a grainy or clumpy texture on your donut bars.
Technique Tips
- Cream butter and granulated sugar for 3-5 minutes on medium speed:Beat 1/2 cup (1 stick) softened butter with 1 cup granulated sugar until the mixture becomes pale yellow and fluffy, increasing significantly in volume. This incorporates crucial air, creating a light, tender cake structure that is essential for a donut-like bar.
- Mix wet and dry ingredients only until just combined, about 30 seconds on low speed:After adding dry ingredients, mix only until no streaks of flour remain and the batter is uniform, but still slightly shaggy. Overmixing develops gluten, resulting in a tough, chewy bar instead of a delicate cake-like texture.
- Bake bars at 350°F (175°C) for 22-28 minutes:The bars are done when the edges are golden brown and a wooden skewer inserted into the center comes out clean or with only moist crumbs attached. An internal temperature of 200-205°F (93-96°C) using an instant-read thermometer is ideal for a fully cooked yet tender crumb.
- Cool baked bars completely for at least 60 minutes:Allow the bars to cool in the pan for 15 minutes before transferring to a wire rack. They must be cooled to room temperature (around 70°F/21°C) before glazing, otherwise, the glaze will melt, run off, and be absorbed, making the bars soggy.
- Adjust glaze consistency with 1/2 teaspoon increments of liquid or powdered sugar:If the glaze is too thick to spread, add 1/2 teaspoon of warm milk; if too thin and runny, whisk in 1/2 tablespoon of sifted powdered sugar. The ideal consistency should be thick enough to coat the back of a spoon and hold its shape for a few seconds before slowly dripping, allowing for an even, opaque layer.
Common Issues
- Bars are too dense or tough:If your bars lack a tender crumb, it’s likely due to overmixing the batter. Ensure you only mix the dry ingredients into the wet for 30 seconds to 1 minute, on the lowest speed, until just combined. Overmixing develops gluten, which toughens the final product.
- Glaze is too thin and runny:To thicken a runny glaze, gradually add 1-2 tablespoons of sifted powdered sugar. Whisk in the powdered sugar, 1 tablespoon at a time, until the glaze reaches a consistency that slowly drizzles off a spoon and coats it evenly without being transparent, preventing it from soaking in or running off.
- Glaze is grainy or lumpy:For a perfectly smooth glaze, ensure powdered sugar is sifted twice before mixing, and that any liquid (like milk) is warmed to 90-100°F (32-38°C). Lumps are often from unsifted sugar, and a grainy texture can result from cold liquid not dissolving the sugar completely.
- Bars stick to the pan:To prevent sticking, line the baking pan with parchment paper, leaving a 2-inch overhang on two opposite sides. Additionally, lightly grease the parchment and exposed pan sides with 1 teaspoon of non-stick spray or melted butter. This creates “handles” for easy lifting after cooling, ensuring the bars release cleanly.
- Bars have a “gummy” or undercooked texture:If the center of your bars is gummy, extend baking time by 3-5 minutes. Ensure the internal temperature reaches 200-205°F (93-96°C) using an instant-read thermometer. The center should spring back slightly when gently pressed, and a wooden skewer should emerge clean, indicating proper doneness.
How to Store and Reheat Maple Donut Bars
Refrigerator Storage
Duration: 5-7 days in airtight container
To maintain their delightful texture and flavor, store Maple Donut Bars in an airtight glass or plastic container. While they remain perfectly edible for 5-7 days, their peak freshness and soft texture are best enjoyed within the first 2-3 days. After this period, the bars may start to dry out slightly, particularly around the edges, and the maple glaze can become a bit stickier or absorb further into the bar. Ensure the container is truly airtight to prevent them from absorbing any unwanted refrigerator odors.
Freezer Storage
Duration: 2-3 months
Maple Donut Bars freeze beautifully. First, allow the bars to cool completely after baking and glazing. For best results, flash freeze them uncovered on a baking sheet for 1-2 hours until solid; this prevents the glaze from sticking to the wrapping. Next, individually wrap each bar tightly in plastic wrap, followed by a layer of aluminum foil. Place the wrapped bars in a heavy-duty freezer bag or an airtight freezer-safe container. To thaw, simply place individual bars at room temperature for 1-2 hours, or overnight in the refrigerator. Freezing can make the texture a touch denser or slightly more crumbly once thawed, and the maple glaze might bloom slightly, appearing duller, but the rich flavor will remain.
Reheating Instructions
- Oven or Toaster Oven (Best for Texture):Preheat your oven or toaster oven to 300°F (150°C). Place thawed or refrigerated bars on a baking sheet. Reheat for 8-12 minutes, or until warmed through and the glaze is slightly glistening. Keep a close eye on them to prevent over-browning. This method works best for restoring a soft, warm interior and lightly crisps the edges, making it the preferred choice for regaining that fresh-baked feel.
- Microwave (Quick but Texture Compromise):Place one bar on a microwave-safe plate. Heat on medium power (50-70%) for 15-30 seconds. Check for warmth and continue in 5-10 second increments if needed. Be cautious not to overheat, as microwaving can quickly make the donut bar tough, chewy, or rubbery, and the glaze can become overly liquid. While a quick option, it’s not ideal for maintaining the original delicate texture.
Make-Ahead Tips
You can prepare several components of Maple Donut Bars in advance. The donut bar dough can be made up to 24 hours ahead; cover it tightly with plastic wrap and refrigerate. Allow it to come to room temperature for about 30 minutes before rolling and baking. Alternatively, bake the bars completely but leave them un-glazed. Store these un-glazed bars in an airtight container at room temperature for up to 2 days, or freeze them as described in the freezer storage section. The maple glaze is best made fresh and applied to warm (or room temperature) bars, but if necessary, it can be stored in an airtight container in the refrigerator for up to 3 days. Gently warm and whisk the glaze well before drizzling, as it may thicken and separate slightly when cold.
