Blondies

These blondies are buttery, tender, and studded with pockets of sweet, creamy white chocolate. The top bakes to a light golden color with slightly crisp edges while the interior stays moist and chewy. Expect warm notes of vanilla and caramelized sugar, a hint of cinnamon from the hidden filling, and a soft crumb that melts on the tongue. They are perfect for afternoon coffee, a potluck dessert, or a cozy movie night treat. If you enjoy experimenting with richer flavors, consider a browned butter variation for added nutty depth, which pairs beautifully with this base recipe browned butter blondies.

Ingredients

3/4 cup unsalted butter, softened to room temperature — brings rich flavor and tender crumb.
3/4 cup granulated sugar — adds sweetness and helps create a lightly crisp top.
3/4 cup packed light brown sugar — contributes moisture and a caramel note.
2 large eggs, room temperature — provide structure and richness.
2 teaspoons pure vanilla extract — enhances sweetness and provides aromatic warmth.
2 and 1/3 cups all-purpose flour — the base for structure and chew.
1 and 1/2 teaspoons baking powder — gives a little lift so the blondies are not too dense.
1/2 teaspoon cream of tartar — helps with tenderness and a slight tang.
1/2 teaspoon salt — balances sweetness and highlights flavors.
1 cup white chocolate morsels — pockets of creamy sweetness throughout.
1 tablespoon white chocolate morsels (for topping) — a decorative, melty finish.
1/4 cup granulated sugar (for cinnamon-sugar filling) — the sugar component for the filling.
2 teaspoons ground cinnamon — mixed with sugar to make a warm cinnamon filling.

Step-by-Step Instructions

Preheat your oven to 350°F (177°C) and line a 9-inch square baking pan with parchment paper. Press the parchment so the corners are smooth for even baking.
In a large bowl, beat the softened butter, granulated sugar, and brown sugar together until fluffy, about 3 minutes. Start on low speed, then increase to medium to avoid sugar blowing out.
Add the eggs and vanilla extract; beat until well combined. Scrape down the bowl once to ensure even mixing.
In a separate bowl, whisk together the flour, baking powder, cream of tartar, and salt. Whisking removes lumps and distributes the leavening evenly.
Gradually add the dry ingredients to the wet mixture, mixing until just combined. Do not overmix to keep the blondies tender.
Gently fold in the white chocolate morsels. Folding preserves the batter texture and prevents chips from sinking.
Press half of the dough into the prepared pan. Use lightly oiled hands or a spatula to evenly press without compacting too much.
In a small bowl, mix the sugar and cinnamon for the filling, and sprinkle over the dough. Tap the pan gently to settle the filling evenly.
Flatten the remaining dough and layer it over the cinnamon-sugar filling. If the dough is sticky, chill for 10 minutes to make it easier to handle.
Press the additional white chocolate morsels on top. This adds a pretty finish and extra bites of chocolate.
Bake for 32-35 minutes, until golden brown, and a toothpick comes out with a few moist crumbs. Start checking at 32 minutes to avoid overbaking.
Allow to cool completely before slicing into squares. Cooling helps the bars set and makes cleaner slices.

Tips, Storage & Variations

Tips

Use room temperature eggs and butter for a smooth, well-emulsified batter.
Line the pan with parchment with an overhang to lift the blondies out easily.
If the top browns too quickly, tent loosely with foil for the last 5 to 10 minutes of baking.

Storage

At room temperature: Store cooled blondies in an airtight container for up to 3 days.
Refrigeration: Keep in an airtight container for up to 1 week to extend freshness.
Freezing: Wrap individual squares tightly in plastic wrap and place in a freezer bag for up to 3 months. Thaw overnight in the refrigerator or at room temperature for a few hours.

Variations using existing ingredients only

Cinnamon-forward: Increase the cinnamon in the filling to 1 tablespoon for a stronger spice note.
Extra white chocolate: Fold an extra 1/4 cup of the white chocolate morsels into the batter for more pockets of sweetness.
Thicker filling layer: Double the cinnamon-sugar filling amounts by adjusting how much you sprinkle between the layers to emphasize the swirl.
