These brown sugar pecan blondies are chewy, buttery dessert bars with crisp edges and a hint of vanilla—an easy homemade treat for a Conyers kitchen. Brown sugar gives them a soft, caramel-like flavor, while toasted pecans add crunch; serve them warm or let them cool for neat slices.
Ingredients
- 1 cup (226 g) unsalted butter, melted and cooled for 5 minutes
- 1 ½ cups (330 g) packed light brown sugar
- 1 large egg (about 50 g without shell), at room temperature
- 1 large egg yolk (about 18 g), at room temperature
- 2 teaspoons (10 ml) vanilla extract
- 2 cups (250 g) all-purpose flour, measured by spooning into the cup and leveling
- ½ teaspoon (2.5 g) baking powder
- ½ teaspoon (3 g) fine salt
- ¾ cup (85 g) chopped pecans
- 1 tablespoon (8 g) all-purpose flour, for coating the pecans
- 1 teaspoon (5 g) butter, for greasing the pan
- Flaky salt, optional, for finishing
Instructions
- Set a rack in the middle of the oven and heat it to 350°F (175°C). Grease an 8-inch (20 cm) square metal baking pan with the teaspoon of butter, then line it with a strip of parchment paper, leaving overhang on two sides to lift out the blondies. If using a glass pan, expect the edges to brown a little more slowly.
- In a medium bowl, whisk together the flour, baking powder, and fine salt. In a separate large bowl, whisk the melted butter and brown sugar until evenly combined and no large sugar clumps remain. The mixture will look thick and glossy, not fluffy.
- Whisk in the egg, egg yolk, and vanilla until smooth. Add the flour mixture and fold with a spatula just until no dry streaks remain. Avoid prolonged mixing, which can make the bars tough.
- Toss the chopped pecans with the tablespoon of flour, then fold them into the batter. Coating the nuts helps keep them distributed instead of letting them settle in one spot.
- Scrape the batter into the prepared pan and spread it into an even layer, pressing it gently into the corners. Bake for 22 to 25 minutes, until the top looks set and lightly golden and a toothpick inserted near the center comes out with a few moist crumbs. Do not wait for a completely clean toothpick; that usually means the bars are overbaked. The center should no longer look wet.
- Cool in the pan on a wire rack for 30 minutes, then use the parchment to lift the slab out. Let it cool for another 30 minutes before cutting into 16 squares. Sprinkle with flaky salt, if desired. For especially clean edges, wipe the knife between cuts.
Tips
- Measure flour lightly. Scooping directly with the measuring cup can pack in too much flour and leave the blondies dry. For the best accuracy, weigh it; otherwise spoon it into the cup and level the top.
- Use soft, fresh brown sugar. If it has hardened, break it up before mixing. Dark brown sugar works in the same quantity and gives a deeper molasses flavor, though the bars may taste slightly less buttery-sweet.
- Watch the center, not just the edges. Pull the pan when the center is set but still tender. Metal pans vary, so begin checking at 22 minutes; extra baking can quickly turn chewy bars dry.
- Toast the pecans for more flavor. Spread them on a small baking sheet and toast at 350°F (175°C) for about 5 to 7 minutes, watching closely. Cool completely before adding them to the batter.
Serving Suggestions
Serve the squares at room temperature for a chewy texture, or warm an individual piece briefly and add a scoop of vanilla ice cream. A spoonful of whipped cream or a few fresh berries also balances the rich brown-sugar flavor. For a dessert tray, cut the cooled slab into smaller squares and offer coffee, tea, or cold milk alongside.
These bars are rich, so modest portions work well after a full meal. If serving warm with ice cream, warm only the portion you plan to eat; reheating the whole pan can dry out the edges before the center warms.
Variations
- Chocolate chip: Replace half the pecans with ½ cup (85 g) semisweet chocolate chips. Keep the total additions close to the original amount so the bars still hold together.
- Nut-free: Leave out the pecans and add ½ cup (60 g) rolled oats or ½ cup (85 g) chocolate chips. Check labels if the bars are being served to someone with a serious nut allergy.
- Spiced: Add ½ teaspoon (1 g) ground cinnamon to the dry ingredients. A small pinch of ground ginger is another option, but keep the spices modest so they do not overpower the brown sugar.
- Salted caramel-style: Use dark brown sugar and finish with a light sprinkle of flaky salt. Dark sugar brings stronger molasses notes; it does not turn the bars into caramel, so no extra cooking step is needed.
Storage and Reheating
Let the blondies cool completely, then store them in an airtight container. They keep at room temperature in a cool, dry place for up to 3 days; refrigerate them if your kitchen is hot or if you prefer a firmer texture. Refrigerated bars keep for 3 to 4 days. Refrigerate within 2 hours if they have been served with perishable toppings such as ice cream or whipped cream.
For longer storage, freeze the cut bars in a freezer-safe container with parchment between layers for up to 2 months. Thaw at room temperature for about 1 hour. To serve warm, microwave one bar for 8 to 12 seconds, then check and add a few seconds if needed. Avoid overheating, which makes the edges hard.
Frequently Asked Questions
Can I use dark brown sugar instead of light?
Yes. Use the same weight, 330 g, or the same volume, 1 ½ packed cups. Dark brown sugar contains more molasses, so the blondies will have a deeper, slightly more pronounced molasses flavor.
Can I make these without pecans?
Yes. Omit them for plain blondies, or replace them with an equal volume of chocolate chips or rolled oats. The bake time should remain close, but still check for a set center and moist crumbs on the toothpick.
Why did my blondies turn out cakey?
Too much flour, overmixing, or overbaking can make them cakey or dry. Weigh the flour if possible, fold only until the dry streaks disappear, and start checking at 22 minutes.
Can I bake this recipe in a 9-inch pan?
Yes, but the batter will be thinner and will bake faster. Begin checking around 18 minutes. The exact time depends on the pan and oven, so use the visual cues—a set, lightly golden top and a toothpick with moist crumbs—rather than relying only on the clock.
How do I know when the blondies are done?
The top should look set, the edges should be lightly golden, and the center should not look wet. A toothpick near the middle should have a few moist crumbs but no raw batter. They continue to firm as they cool.
Can I make the batter ahead?
For the best texture, bake it soon after mixing so the baking powder can do its job. You can bake the bars a day ahead and store them covered; cool completely before sealing the container to avoid trapping steam.
