How to Make Cinnamon Streusel White Chocolate Blondies Recipe

Step 1: Preheat and Prepare

Start by heating your oven to 350 degrees Fahrenheit and line a 9×13 inch pan with parchment paper for easy removal later. This simple step ensures your blondies get the perfect bake and clean lifts without any fuss.

Step 2: Cream Butter and Sugars

In a large bowl, combine the melted salted butter with both the brown and granulated sugars. Beat until the mixture is light, fluffy, and smells incredibly sweet, setting a delicious base that’s key to chewy blondies.

Step 3: Add Eggs and Vanilla

Mix in two whole eggs and one egg yolk along with your vanilla extract. These enrich the batter and lend a silky texture that will shine through when baked.

Step 4: Incorporate Dry Ingredients and Chocolate

Now fold in half of the flour, salt, and baking powder gently, then add the remaining flour plus the white chocolate chips. Mixing just until everything comes together ensures your blondies stay tender, with pockets of melted chocolate bliss waiting inside every bite.

Step 5: Make the Streusel Topping

In a small bowl, combine the flour, brown sugar, granulated sugar, cinnamon, salt, and softened butter. Use a fork to blend until the mixture forms pea-sized crumbs. This topping will add a deliciously crisp, cinnamon-sweet crunch.

Step 6: Assemble and Bake

Spread the blondie batter evenly into the prepared pan. Sprinkle the cinnamon streusel topping generously across the surface. Pop it into the oven and bake for 25 to 28 minutes, or until the blondies are set and the streusel is lightly golden. Let them cool before lifting from the pan and slicing into 24 perfect squares.

The cake has two visible layers: a light tan base layer with a soft texture and small visible pieces inside, and a thick crumb topping with a slightly darker tan color made of small, coarse crumbs. The crumb layer looks rough and crumbly, covering the entire top. The background shows more pieces of the same crumb cake on a white marbled surface, softly blurred to keep focus on the held piece.

Garnishes

For an inviting finish, dust a light sprinkle of powdered sugar or a pinch of cinnamon over the top of your blondies. A drizzle of white chocolate sauce or a dollop of whipped cream can also elevate these treats to pure indulgence.

Side Dishes

Pair these blondies with a scoop of vanilla ice cream or a cup of your favorite coffee or tea. The creamy cold ice cream contrasts wonderfully with the warm, spiced blondies, making every bite a little moment of joy.

Creative Ways to Present

Try serving your Cinnamon Streusel White Chocolate Blondies Recipe on a rustic wooden board with fresh berries scattered around. Or pile them high in a mason jar for an adorable gift idea that friends and family will adore. You can even cut them into mini bite-sized pieces for party platters.

Make Ahead and Storage

Storing Leftovers

Keep your blondies fresh by storing them in an airtight container at room temperature. They’ll stay moist and delicious for up to 4 days, making them a great treat to enjoy over several days without losing any charm.

Freezing

If you want to enjoy these blondies later, wrap them tightly and freeze for up to 3 months. Make sure to separate layers with parchment paper so they don’t stick together, and thaw them overnight when ready to indulge.

Reheating

To bring your Blondies back to that just-baked warmth, pop them in a microwave for about 15 seconds or heat briefly in a low-temperature oven. This revives their softness and enhances the aroma of cinnamon and white chocolate.

FAQs

Can I use unsalted butter for this recipe?

Absolutely! Just add a pinch more salt to your batter and streusel to balance the flavors perfectly.

Do I have to use white chocolate chips?

White chocolate adds a lovely sweetness and creamy texture, but you can also experiment with milk or dark chocolate chips if you prefer a richer flavor profile.

Can I make the streusel topping ahead of time?

Yes, you can prepare the streusel topping a day in advance and keep it refrigerated until ready to bake. Just give it a quick crumble before sprinkling over the blondies.

How do I know when the blondies are done baking?

They’re ready when the edges are set and the center springs back slightly when lightly pressed. A toothpick inserted should come out with a few moist crumbs, but not wet batter.

Can I substitute gluten-free flour?

Yes, using a 1-to-1 gluten-free all-purpose flour blend usually works well. Just be sure your blend includes xanthan gum or another binder to maintain the blondies’ texture.
