Ingredients for blondies sugar cookies copycat

Pantry staples transformed into bakery-quality blondies with a toasted pecan twist.

The cake mix is the foundation, but brand matters. Betty Crocker Super Moist or Duncan Hines Classic White deliver consistent results—avoid the dry varieties. For the butter, Plugrá or Land O'Lakes are reliable, but never use margarine. The brown sugar should be light and packed—dark brown sugar adds unwanted molasses depth. Toast your pecans in a dry skillet over medium heat for 5-7 minutes until fragrant and golden; Costco or Trader Joe's sell pre-toasted pecans if you're short on time, but fresh-roasted always tastes superior.

No vanilla extract? Vanilla bean paste works in a pinch, or almond extract at half the amount for a subtle nutty note. Running low on baking powder? Baking soda plus cream of tartar substitutes at a 3:1 ratio. For the granulated sugar topping, turbinado sugar creates a crunchier crust, but regular granulated delivers the classic caramelized finish. The heavy cream is optional but elevates the blondies to a decadent level—Hillfarm or Organic Valley are my go-tos for quality. If you prefer a gluten-free version, swap the cake mix for a gluten-free vanilla blend and add an extra 0.5 cup of almond flour.

Store baked blondies in an airtight container at room temperature for up to 5 days, or freeze for 3 months for maximum freshness. For the best texture, let them cool completely before slicing—this prevents a gummy center. Portion into single servings before freezing if you plan to reheat; a 30-second microwave burst restores that bakery-warm quality. The toasted pecans keep their crunch for 1 week in the fridge if stored separately, so toast a fresh batch whenever you're ready to bake.

Step-by-step instructions for blondies sugar cookies copycat recipe

This method delivers bakery-quality blondies with a perfect blend of cake mix convenience and homemade texture.

In a medium bowl, melt the 0.5 cup unsalted butter in 30-second intervals in the microwave, stirring between each interval until fully melted but not hot. Let it cool for 2 minutes—this prevents scrambling the eggs later. Add the 1 cup packed light brown sugar and whisk until completely dissolved.

In a separate small bowl, beat the 2 whole large eggs at room temperature until just combined, then whisk in the 1 tablespoon pure vanilla extract. The eggs should be smooth with no streaks, ensuring even distribution throughout the batter. This step creates the foundation for the blondies' signature chewy texture.

In a large mixing bowl, add the 1 box all-purpose cake mix, 0.25 cup all-purpose flour, 0.5 teaspoon baking powder, and 0.25 teaspoon diamond crystal kosher salt. Mix these dry ingredients together until evenly distributed—this prevents lumps and ensures uniform texture throughout the blondies.

Gradually pour the melted butter and sugar mixture into the dry ingredients while mixing on low speed with a hand mixer. Add the egg mixture and mix just until combined, scraping down the sides of the bowl as needed. The batter should be thick but pourable—if it appears too dry, add 1 tablespoon heavy cream to achieve the right consistency.

Using a silicone spatula, gently fold in the 1.5 cups toasted pecans and 0.25 cup granulated sugar until evenly distributed. The pecans should be spread throughout the batter without breaking apart, while the granulated sugar will create pockets of caramelized sweetness when baked. Avoid overmixing—this maintains the blondies' tender crumb.

For extra richness, drizzle in the 0.25 cup heavy cream and fold it in until fully incorporated. The cream adds moisture and a subtle tang that balances the sweetness. If the batter seems too thick, add 1 more tablespoon heavy cream to ensure the blondies bake evenly without being dense.

Preheat your oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Spread the batter evenly into the pan, using the back of a spoon to smooth the top. The surface should be level—this ensures even baking and a consistent texture.

Bake for 22-25 minutes until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs (not wet batter). The blondies should pull away slightly from the edges of the pan, indicating they're fully set. If the top browns too quickly, tent the pan with aluminum foil to prevent over-browning while the center finishes baking.

Remove the blondies from the oven and let them cool in the pan for 10 minutes before transferring to a wire rack to cool completely. This gradual cooling prevents cracking and allows the blondies to set properly. Once fully cooled, use a sharp knife or pizza cutter to slice into 24 squares—the classic blondie shape.

For best results, store the blondies in an airtight container at room temperature for up to 5 days or freeze for up to 3 months. The toasted pecans will retain their crunch, while the cake mix base ensures a tender, slightly crispy exterior with a soft, chewy center—just like the original copycat recipe promises.

Serving suggestions for this recipe

Classic Serving Style

Serve these blondies warm straight from the oven for maximum indulgence—the caramelized edges and toasted pecans are at their peak. I like arranging them on a marble slab or wooden board for a rustic touch, then dusting with a light layer of powdered sugar using a fine-mesh sieve.

For a nostalgic presentation, cut them into the classic 24 squares and stack them neatly on a platter. 🍴

Ice Cream Pairing

Pair blondies with a scoop of vanilla bean ice cream or coffee-flavored gelato for a decadent dessert. I recommend Ben & Jerry's Phish Food for its caramel swirls or Häagen-Dazs French Vanilla for a creamy contrast.

For a lighter option, try coconut milk ice cream to balance the richness without overpowering the blondies.

Coffee or Tea Companion

These blondies are perfect with a hot cup of coffee or Earl Grey teadark roast like Peet's Major Dickason's Blend or steep Twinings English Breakfast for a robust pairing. The caffeine helps cut through the sweetness, making each bite feel lighter.

Gift-Worthy Presentation

For gifting, package blondies in clear cellophane bags tied with a ribbon**> and a handwritten tag. I like adding a small jar of hot fudge sauce on the side for dipping.
