Lemon Blondies with Raspberries are the perfect amount of sweet, tangy, yet delectable treat. These blondies are a summer staple. Cakey, yet chewy blondies with raspberries are by far one of the best desserts in my opinion. They combine two of the best desserts, cookie in the form of a brownie, what could be better? This tart raspberry blondies recipe uses a shortcut by starting with a box of lemon cake mix.

Instructions

Preheat oven to 350F.

Grease a 8″ x 8″ casserole dish and set aside.

In a large bowl, beat together the cake mix, vegetable oil, eggs and vanilla extract for 2 minutes until well combined and fluffy.

Pour the batter into the prepared baking dish.

Press the raspberries into the batter, then use a spatula to even out the top of the batter and slightly cover the majority of the raspberries.

Bake for 20-24 minutes until an inserted toothpick comes out clean.

Allow the blondies to cool completely before preparing the glaze.

In a small bowl, whisk together all glaze ingredients.

Pour the glaze all over the blondies and smooth over with an offset spatula until blondies are completely covered.

Allow the glaze to set for at least 1 hour before cutting the blondies to store or serve.

Tips & Tricks (5)

Cake Mix Magic 🎂
Sift the lemon cake mix before mixing to eliminate any lumps and ensure a smoother, more uniform texture in your blondies.
Raspberry Distribution Technique 🫐
Gently toss raspberries in a light coating of flour before folding into the batter to prevent them from sinking during baking.
Zesty Lemon Boost 🍋
Add fresh lemon zest to the batter for an extra burst of citrus flavor that complements the cake mix's lemon profile.
Perfect Cutting Trick 🔪
Use a hot, clean knife and wipe it between cuts to achieve clean, professional-looking blondie squares.
Moisture Preservation 💧
Allow blondies to cool completely in the pan before cutting to help them set and retain maximum moisture.
