These cinnamon sugar blondies are so easy to make, just follow my simple instructions.

Prepare Your Baking Sheet

Start by lining an 8×8-inch baking sheet with parchment paper, then preheat your oven to 350°F (180ºC). This is key to making sure those blondies pop right out of the pan without sticking. Plus, cleanup becomes a breeze.

Combine Dry Ingredients

In a separate bowl, whisk together the flour, baking powder, and salt. This little step ensures your blondies will bake up evenly, so don’t skip it! Set the bowl aside for now.

Cream Butter and Brown Sugar

In a larger bowl, grab your butter and brown sugar. Using an electric mixer, blend them on medium speed for about 5 minutes.

What you’re looking for is a creamy, fluffy mixture—this is what will give your blondies that rich, soft texture we’re after.

Add Eggs and Vanilla

Next, toss in the eggs and vanilla extract and keep mixing for another couple of minutes. This step builds up the flavor and makes everything come together into one smooth batter.

Fold in the Dry Ingredients

Now, gently fold your dry ingredient mix into the wet ingredients. Use a spatula or spoon and stir just until everything is combined. No need to overdo it—overmixing can make your blondies denser than you want.

Spread and Top with Cinnamon Sugar

Spoon the batter into your prepared baking sheet, making sure it’s spread out evenly. In a small bowl, stir together the cinnamon and sugar, then sprinkle that sweet goodness all over the top of your batter. This will create that delicious, slightly crunchy topping you’ll love with every bite.

Bake

Pop the pan into your preheated oven and let it bake for 35-40 minutes. Start checking around 30 minutes.

When a toothpick inserted into the center comes out clean or with just a few moist crumbs, your blondies are good to go. Let them cool in the pan for a few minutes before glazing.

Glaze the Blondies

While your blondies cool, whisk together powdered sugar and milk to make a simple glaze. Once the blondies are fully cooled, drizzle the glaze on top.

Let the glaze set for a few minutes, then cut into squares, serve and enjoy!

Recipe Notes and Expert Tips

Here’s some extra notes and tips of things I’ve learned while developing the recipe.

• Don’t Overmix: Be gentle when folding in the dry ingredients. Overmixing can make your blondies dense instead of soft and chewy.
• Softened Butter: Make sure your butter is at room temperature for easy creaming. Cold butter won’t blend properly, and melted butter will throw off the texture.
• Glaze Consistency: Want a thicker glaze? Use less milk. For a thinner, more drizzle-like consistency, add a little more.
• Check Early: Oven temperatures can vary, so start checking your blondies at the 30-minute mark to avoid overbaking them. You want them slightly soft in the center.
• Topping Tip: Add a bit of coarse sugar to the cinnamon-sugar mix for an extra crunchy top layer.
• Let Them Cool: Cutting into warm blondies can make them crumble. Let them cool completely for clean slices.
• Scaling Up: Feeding a crowd? You can double the recipe and use a 9×13-inch pan. Just watch the baking time—it might need a few extra minutes.

How to Store Leftover Cinnamon Sugar Blondies

If you’ve got leftovers, store them in an airtight container at room temperature for up to 3 days. If you prefer, you can refrigerate them for up to a week to keep them fresh longer.

For those who like to plan ahead, you can freeze the blondies for up to 3 months. Just wrap them tightly in plastic wrap and place them in a freezer-safe container. When you’re ready to eat, let them thaw at room temperature or pop them in the microwave for a few seconds.
