Ingredients Needed

Yellow Cake Mix-The perfect base for these amazing shortbread cookies.
Butter-Used in a softened state, the butter helps give the shortbread dough a wonderful buttery flavor.
Egg-Adding an egg to the cookie dough helps to bind the ingredients together and gives them wonderful texture.
Raspberry Jam-Use whatever you have on hand but a good quality raspberry jam works wonderful.

How to make Raspberry Crumble Cookies with a Cake Mix

Mix dry cake mix, softened butter and egg with either a wooden spoon or an electric mixer. The mixture will be crumbly and that is how it should be.
Add 2 tablespoons of shortbread dough into each muffin cup.
Use a small glass {or shot glass or tart shaper} to pack the dough into the cup.
Add 2 teaspoons of jam to the top of the shortbread dough and spread it out making sure to not take it out to the edges.
Crumble 1 tablespoon of shortbread dough over jam.
Bake for 22-25 minutes or until the jam is bubbling and the edges are turning golden brown. Remove from the oven and let them cool completely on a cooling rack. If you love glaze then combine the ingredients one the cookies are cooled and drizzle over the top of the cookies.

Tips for the perfect Crumble Cookies

Line the muffin pan with parchment squares or cupcake liners. This will ensure that the cookies don’t stick to the pan and allow you to remove them easily.
Don’t skip the step of pressing down the shortbread dough into the pan for the bottom layer. Pressing down the cookie dough will give you a nice sturdy base.
When you add the jam don’t spread it all of the way to the edges of the dough. This helps to keep the filling in the center of the cookie and also keeps the jam from sticking to the sides of the pan.
Allow the cookies to bake at the lower temperature for a bit longer. Most recipes don’t call for a 325 degree oven but to get shortbread cooked through well and a nice texture, this step is important.
Don’t add the glaze until the cookies are totally cooled. Otherwise, the glaze will melt.

Frequently Asked Questions:

How do they compare to Costco’s Raspberry Crumble Cookies?

There are definitely some good similarities between this Cake Mix Raspberry Crumble Cookie recipe and the ones you get at Costco. The flavor profile and texture are super close which is so wonderful.

The difference would be the size. Costco’s Raspberry Crumble Cookies are larger than the cookie in this recipe but I think this is a good copycat recipe.

Can I use a different sized muffin tin?

You could use a mini muffin or jumbo muffin pan for this recipe to get smaller or larger cookies. Everything about the recipe would work exactly the same, except the baking times would need to be modified.

Can I use another flavor of jam for these Easy Raspberry Crumble Cookies?

Any flavor of jam would work great in this Easy Raspberry Crumble Cookie recipe. In fact, I am thinking of making a strawberry version soon.

Blueberry, blackberry, apricot and even peach would all be wonderful flavors of jam to use in this recipe too!

Ingredients

Cookie

1 box yellow cake mix {15.25 ounces}
⅓ cup butter {softened}
1 egg
½ cup raspberry jam

Glaze

1 cup powdered sugar
½-2 Tablespoons milk
⅛ teaspoon corn syrup {optional}

Instructions

Preheat oven to 325 degrees. Grease a 12 count muffin pan {or line with cupcake liners} and set aside. Mix dry cake mix, softened butter and egg with either a wooden spoon or an electric mixer. The mixture will be crumbly and that is how it should be. Add 2 tablespoons of shortbread dough into each muffin cup. Use a small glass {shot glass or tart shaper} to pack the dough into the cup. Add 2 teaspoons of jam to the top of the shortbread dough and spread it out making sure to not take it out to the edges. Crumble 1 tablespoon of shortbread dough over jam. Bake for 22-25 minutes or until the jam is bubbling and the edges are turning golden brown. Remove from oven and let them cool completely on a cooling rack.
Once the cookies are cool, combine the glaze ingredients and whisk until smooth. The mixture should be thin enough to drizzle on the cookies but thick enough to stay on top. Sprinkle with powdered sugar {if desired} and enjoy. Store leftovers in an airtight container at room temperature for up to 3 days.

Notes

Use a different kind of jam in the middle of the cookies for a different but delicious flavor. Strawberry, blueberry, blackberry, apricot and peach would all be amazing.
