These Brown Sugar Pop-Tart Blondies begin with a rich, buttery blondie base, layered with a thick brown sugar–cinnamon filling, and finished with a smooth cinnamon glaze — all the warm, nostalgic flavors of a Brown Sugar Cinnamon Pop-Tart transformed into a fudgy bar.
If you loved Pop-Tarts as a kid, these blondies capture that same cozy, sweet feeling in every bite. The brown sugar and cinnamon filling is generous and gooey, the blondie base is tender and slightly chewy, and the cinnamon icing on top seals the deal. This recipe highlights the beloved brown sugar cinnamon flavor — buttery, warm, and infinitely comforting.
Baking the Pop-Tart flavor into a bar makes serving, sharing, and storing easier than dealing with individual pastries. These bars travel well, slice neatly for lunchboxes or bake sales, and are simple to make with pantry-friendly ingredients.
Why you’ll love these Brown Sugar Pop-Tart Blondies
- Buttery blondie base that is tender, chewy, and rich without being overly dense.
- A thick, gooey brown sugar–cinnamon filling instead of a thin smear—every bite tastes like the best part of the Pop-Tart.
- Sweet cinnamon glaze on top for the classic finishing touch that ties the flavors together.
Tips for storing these bars
- Store at room temperature in an airtight container for up to 5 days. Keep them layered with parchment between rows to prevent sticking.
- Freeze for longer storage: arrange bars in a single layer on a baking sheet to flash-freeze, then transfer to a freezer-safe bag or container for up to 3 months. Thaw at room temperature before serving.
- If you prefer softer icing after refrigeration, allow the bars to come to room temperature for 20–30 minutes so the glaze relaxes slightly.
Even if you usually reach for strawberry or raspberry Pop-Tarts, these brown sugar cinnamon blondies are worth trying — the familiar flavor is elevated by the blondie texture and a generous filling that makes them feel indulgent and nostalgic at the same time.

Description

Ingredients
Blondie layer:
- 3/4 cup (1 1/2 sticks) butter, melted
- 3/4 cup brown sugar
- 1/4 cup granulated sugar
- 1 large egg
- 1 large egg yolk
- 1 teaspoon pure vanilla extract
- 2 cups all-purpose flour
- 1/2 teaspoon kosher salt
Brown sugar layer:
- 3/4 cup packed light brown sugar
- 2 teaspoons ground cinnamon
- 3 tablespoons butter, melted
- 1 tablespoon flour
Icing:
- 1 cup powdered sugar
- 3 tablespoons dark brown sugar (or light brown sugar; color will be lighter)
- 1–2 tablespoons half & half or whole milk, start with 1 tablespoon
- 1 tablespoon light corn syrup
- 1/2 teaspoon vanilla extract
- 1/4 teaspoon ground cinnamon
Instructions
Blondie Layer:
- Preheat the oven to 350°F (175°C). Line a 9″ x 9″ pan with parchment and lightly spray the parchment with cooking spray for easy release.
- In a large bowl, whisk the melted butter with the brown sugar and granulated sugar until smooth. Add the egg, egg yolk, and vanilla, whisking until combined.
- Add the flour and kosher salt and mix until just combined—do not overmix.
- Press the batter evenly into the prepared pan to form the blondie base.
Brown Sugar Layer:
- In a small bowl, stir together the packed brown sugar, ground cinnamon, melted butter, and 1 tablespoon flour; it will form a thick, paste-like filling.
- Spread the cinnamon–brown sugar mixture over the blondie layer, leaving about a 1/4″ border around the edges so the filling doesn’t spill out while baking.
- Bake for 25–30 minutes, until the edges are set and lightly golden; the center should still feel slightly soft to the touch. Allow the bars to cool completely in the pan before icing.
Icing:
- In a small bowl, whisk together the powdered sugar, brown sugar, 1 tablespoon half & half (or milk), corn syrup, vanilla, and cinnamon.
- Add additional half & half a splash at a time until the icing is smooth and spreadable but not too thin.
- Spread the icing over the cooled blondies. Let the glaze set before slicing into 16 bars. Store as noted above.
Notes and variations
- For a richer glaze color and deeper flavor, use dark brown sugar in the icing.
- If the filling seems too stiff to spread, microwave briefly (5–10 seconds) to soften, then spread quickly.
- To make individual-looking Pop-Tart slices, score the top lightly before cutting to create rectangle portions, or use a fork to create decorative lines in the glaze.
