There’s something magical about a pan of Blueberry Blondies cooling on the counter. The edges turn lightly golden, the center stays soft and chewy, and bursts of juicy blueberries melt into buttery vanilla batter. I’m Chef James, and here at Tiramisucake.com, I’ve baked hundreds of desserts but these Blueberry Blondies remain one of my favorite quick-bake treats for busy families.
If you love approachable, bakery-style desserts that come together in one bowl, this recipe is for you. Much like our Classic Tiramisu Recipe (our beloved dessert pillar), these blondies focus on balance sweetness, texture, and simplicity. And if you enjoy fruit-forward sweets, you might also love our Berry Cheesecake Trifle, No-Bake Strawberry Tiramisu, or Lemon Mascarpone Tiramisu.
From an E-E-A-T perspective, this recipe has been tested multiple times in my kitchen for consistency and structure. Because we’re baking with eggs and fresh fruit, proper storage matters. According to the USDA, baked goods containing perishable ingredients should be stored safely at proper temperatures (see full guidance at https://www.fsis.usda.gov/).
Let’s bake something unforgettable.

Ingredients Needed
Dry Ingredients
- 2 cups (250g) all-purpose flour – Provides structure. King Arthur flour works beautifully.
- 1 tsp baking powder – Light lift.
- ½ tsp salt – Balances sweetness.
Wet Ingredients
- ¾ cup (170g) unsalted butter, melted – Creates chewy texture.
- 1 ½ cups (300g) light brown sugar – Moisture + caramel notes.
- 2 large eggs, room temperature – Structure and richness.
- 2 tsp pure vanilla extract – Flavor depth.
Fruit
- 1 ½ cups fresh blueberries (or frozen, not thawed) – Toss lightly in flour to prevent sinking.
Chef James Tip: If using frozen blueberries, fold gently to prevent purple streaking.
