Coffee Cake Cookies with Crunchy Crumb Topping
Soft cinnamon cookies topped with buttery coffee cake crumbs and finished with a sweet glaze.
Coffee cake and cookies are both classic comfort treats. This recipe combines the best parts of each into one bakery-style dessert. The cookies are soft and chewy, thanks to the combination of brown sugar, egg yolk, and cornstarch. On top sits a buttery cinnamon crumb that mimics the signature topping found on traditional coffee cake. A simple cinnamon glaze ties everything together and adds the perfect finishing touch.
The result is a cookie that looks impressive but is surprisingly easy to make at home.

Ingredients Breakdown
For the Cookies
- ½ cup unsalted butter – Provides richness and allows better control over salt levels.
- ½ cup brown sugar – Adds moisture and creates a softer cookie.
- ¼ cup granulated sugar – Helps the edges develop a slight crispness.
- 1 large egg + 1 egg yolk – The extra yolk adds richness and improves texture.
- 2 teaspoons vanilla extract – Enhances all the flavors.
- ½ teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt – Balances sweetness.
- 1 teaspoon cinnamon – Gives the cookie its classic coffee cake flavor.
- 1 tablespoon cornstarch – Creates a softer, chewier texture.
- 1¾ cups all-purpose flour – Provides structure.
For the Crumb Topping
- ½ cup flour
- ⅓ cup brown sugar
- 1½ teaspoons cinnamon
- Pinch of salt
- 4 tablespoons softened butter
This mixture creates the signature coffee cake crumb topping. The butter binds everything together while keeping the topping tender and crumbly.
For the Glaze
- 1 cup powdered sugar
- A generous sprinkle of cinnamon
- 1–2 tablespoons milk
The glaze should be thick enough to drizzle but thin enough to flow smoothly over the cooled cookies.
Equipment Needed
- Stand mixer or hand mixer
- Mixing bowls
- Cookie scoop
- Baking sheets
- Parchment paper
- Cooling rack
Step-by-Step Instructions
Step 1: Prepare the Oven
Preheat the oven to 375°F (190°C).
Line two baking sheets with parchment paper. This prevents sticking and helps the cookies bake evenly.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, beat together:
- ½ cup unsalted butter
- ½ cup brown sugar
- ¼ cup granulated sugar
Mix for 2–3 minutes until the mixture becomes light and fluffy. Proper creaming introduces air into the dough and helps create a softer cookie.
Step 3: Add the Wet Ingredients
Mix in:
- 1 large egg
- 1 large egg yolk
- 2 teaspoons vanilla extract
Continue mixing until fully incorporated.
Chef’s Tip: Room-temperature eggs blend more easily and create a smoother dough.
Step 4: Add the Dry Ingredients
Gradually add:
- Baking powder
- Baking soda
- Salt
- Cinnamon
- Cornstarch
- Flour
Mix only until no dry streaks remain.
Avoid overmixing. Excess mixing develops gluten, which can make cookies dense instead of soft.
Step 5: Shape the Cookies
Using a large cookie scoop, portion the dough into 3-tablespoon balls.
Place them on the prepared baking sheets, leaving enough space between each cookie.
Use your thumb or the back of a measuring spoon to create a shallow indentation in the center of each dough ball.
Step 6: Make the Crumb Topping
In a separate bowl, combine:
- ½ cup flour
- ⅓ cup brown sugar
- 1½ teaspoons cinnamon
- Pinch of salt
Add the softened butter and mix until coarse crumbs form.
The texture should resemble damp sand with some larger crumb pieces.
Step 7: Fill the Centers
Gently press the crumb mixture into the indentation of each cookie.
Do not pack the crumbs too tightly. A loose topping creates better texture after baking.
Step 8: Bake
Bake for 9–12 minutes or until:
- The edges are lightly golden brown.
- The centers appear set but still slightly soft.
For most ovens, 10–11 minutes produces the best balance of softness and structure.
Step 9: Cool Completely
Allow the cookies to rest on the baking sheet for 5 minutes before transferring them to a cooling rack.
The cookies will continue cooking slightly from residual heat.
Step 10: Make the Glaze
Whisk together:
- 1 cup powdered sugar
- Cinnamon
- 1–2 tablespoons milk
Start with 1 tablespoon of milk and add more as needed.
Drizzle the glaze over completely cooled cookies.
Chef’s Tips for Success
Measure Flour Correctly
Spoon flour into your measuring cup and level it off. Scooping directly from the bag can add too much flour and result in dry cookies.
Don’t Overbake
The cookies should look slightly underdone in the center when removed from the oven. They will finish setting as they cool.
Use Room-Temperature Ingredients
Butter, eggs, and egg yolks mix more evenly and produce a smoother dough.
Make Larger Crumbs
For a bakery-style appearance, leave some larger crumb pieces when mixing the topping.
Let the Cookies Cool Before Glazing
Applying glaze to warm cookies will cause it to melt and disappear into the surface.
Storage Instructions
Store the cookies in an airtight container at room temperature for up to 4 days.
For longer storage, freeze the baked cookies without glaze for up to 2 months. Thaw and glaze before serving.
