There’s something magical about the smell of cinnamon and sugar baking in the oven that instantly takes me back to my childhood.
Last week, when I was craving something sweet but didn’t want to commit to a whole batch of cookies, I created these incredible Snickerdoodle Blondie Bites – and let me tell you, they disappeared faster than I could frost them!
These adorable little treats combine all the warm, cozy flavors of classic snickerdoodle cookies with the chewy, fudgy texture of blondies.
Plus, they’re absolutely perfect for turning into spooky mummy treats for Halloween! My kids Isabella, Emma, and Noah couldn’t stop giggling when they saw the little monster eyes peeking through the frosting “bandages.”
Trust me, these high protein cheesecake jars might be healthy, but sometimes you need a sweet indulgence like these blondie bites.

Ingredients for Cinnamon Sugar Blondies
For the blondies:
- 1 cup unsalted butter, softened
- 1½ cups granulated sugar
- 2 large eggs
- 2¾ cups all-purpose flour
- 2 teaspoons cream of tartar (this is the secret!)
- 1 teaspoon baking soda
- ¼ teaspoon kosher salt
For the cinnamon-sugar topping:
- 2 tablespoons granulated sugar
- ¾ teaspoon ground cinnamon
For the vanilla frosting:
- ¼ cup unsalted butter, softened
- 1 cup powdered sugar
- ½ teaspoon vanilla extract
- 2 teaspoons milk
- Edible monster eyes or chocolate chips (optional, for mummy decoration)
How to Make Perfect Snickerdoodle Bars Recipe
Step 1: Prep Your Pan
Preheat your oven to 350°F and line a 13×9 inch baking dish with parchment paper.
This makes removal so much easier later!
Step 2: Make the Blondie Base
In a large mixing bowl, beat the softened butter with granulated sugar for about 2 minutes until light and fluffy.
Add the eggs one at a time, beating well after each addition.
Step 3: Add Dry Ingredients
Mix in the flour, cream of tartar, baking soda, and salt.
Beat just until the dough comes together – don’t overmix or your blondies will be tough instead of tender.
Step 4: Press and Top
Pour the cookie dough into your prepared dish and press it evenly into the bottom.
In a small bowl, mix the 2 tablespoons of sugar with cinnamon, then sprinkle this cinnamon-sugar mixture generously over the unbaked blondies.
Step 5: Bake to Perfection
Bake for 22-25 minutes, until a toothpick inserted in the center comes out clean.
The edges should look set and the center should be puffed.
Let cool completely before frosting.
Step 6: Make the Frosting

Beat the softened butter, powdered sugar, vanilla, and milk together for 3-5 minutes until the frosting is fluffy and smooth.
Step 7: Decorate Your Treats
You have two options here!
For regular bars, simply spread the frosting over the cooled blondies and cut into squares.
For Halloween mummy treats, use a 1.5-inch cookie cutter to cut circles from the cooled blondies, then pipe frosting in stripes using a decorator bag with tip 48.
Add monster eyes or chocolate chips for the spookiest effect!
Storage & Reheating Your Cream of Tartar Blondies
These Snickerdoodle Blondie Bites keep beautifully in an airtight container at room temperature for up to 3 days.
The flavors actually get even better after the first day as everything melds together!
For longer storage, you can freeze these treats for up to 2 months.
I recommend freezing them either completely unfrosted or fully decorated – the in-between stage doesn’t work as well.
When you’re ready to enjoy them, just let them thaw at room temperature for about 30 minutes.
If you want to make these ahead for a party, bake and cool the blondies completely, then wrap them tightly in plastic wrap.
You can frost and decorate them the day of your event for the freshest look.
Creative Halloween Mummy Treats Variations
While the classic mummy design is adorable, you can get creative with these Snickerdoodle Blondie Bites!
Try making:
Spider bites by using chocolate chips for a body and thin pretzel sticks for legs.
Pumpkin treats by tinting the frosting orange and adding green candy for stems.
Ghost bites by keeping the frosting white and using mini chocolate chips for eyes and mouth.
Fall leaf design by using food coloring to create autumn-colored frosting swirls.
The base recipe is so versatile that you can adapt it for any season or occasion.
For Christmas, try adding red and green sprinkles.
For Valentine’s Day, use pink frosting and heart decorations.

FAQs About Snickerdoodle Bars Recipe
Can I bake these Snickerdoodle Blondie Bites as bars instead of bites?
Absolutely!
Press the dough into your 13×9 pan, bake for 22-25 minutes until done, let cool completely, frost the entire surface, then cut into neat squares.
This method is actually faster if you’re making them for a large group.
How do I store or freeze Snickerdoodle Blondie Bites?
Store them in an airtight container at room temperature for up to 3 days.
For freezing, these treats last up to 2 months whether frosted or unfrosted.
Thaw at room temperature for best texture and flavor.
Can I use salted butter or skip the cream of tartar?
You can use salted butter just reduce the kosher salt to a pinch.
If you don’t have cream of tartar, you can substitute the 2 teaspoons cream of tartar plus 1 teaspoon baking soda with 4 teaspoons baking powder, though the flavor won’t be quite as authentic.
How do I know when the blondies are done?
Look for edges that appear set, a center that’s puffed up nicely, and a toothpick that comes out mostly clean when inserted in the center.
This usually takes 22-25 minutes, but every oven is different.

Notes
Don’t skip the cream of tartar this is what gives snickerdoodles their distinctive tangy flavor and chewy texture. Room temperature ingredients mix together much more easily and create a smoother batter. Cool completely before cutting or frosting – warm blondies will make a mess of your decorations.
