Ingredients

  • Unsalted butter: Half a cup at room temperature for rich flavor and soft texture
  • Granulated sugar: One cup for sweetness and structure
  • Eggs: Two large eggs at room temperature to help bind the dough and add moisture
  • Vanilla extract or vanilla bean paste: One teaspoon for warm, mellow flavor bean paste offers little flecks of vanilla seeds for added appeal
  • All-purpose flour: Two and a half cups plus two tablespoons for that tender but sturdy cookie base—spoon and level it for accuracy
  • Fine sea salt: Half a teaspoon to balance the sweetness and enhance flavors
  • Baking soda: Half a teaspoon for gentle leavening and a light crumb
  • Strawberry preserves: Two thirds cup to bring classic fruity sweetness reminiscent of poptarts—with room to swap in jams you love
  • Powdered sugar: One cup for the glaze to add sweetness and striking contrast
  • Whole milk: One and a half to two tablespoons to achieve the perfect glaze consistency
  • Vanilla extract (glaze): Half a teaspoon in the glaze echoes the dough’s flavor
  • Rainbow sprinkles: Rainbow sprinkles for an eye-catching, playful decoration

Step-by-Step Instructions

Prepare the Pan and Oven:
Line an 8 by 8 inch metal baking pan with parchment paper allowing the edges to hang over the sides for easy lifting of the bars later. Preheat your oven to 375 degrees Fahrenheit or 190 degrees Celsius.
Cream the Butter and Sugar:
Using a stand mixer or a hand mixer, beat the room temperature butter with granulated sugar for about three minutes until the mixture becomes light and fluffy. Scrape down the sides of the bowl to ensure everything blends evenly.
Add Eggs and Vanilla:
Add the eggs one at a time along with the vanilla extract or vanilla bean paste. Mix just until combined and scrape the bowl once more to incorporate everything evenly.
Combine Dry Ingredients:
In a separate bowl whisk together the flour, sea salt, and baking soda. Gradually add this dry mixture to the wet ingredients and mix until the dough just begins coming together. Do not overmix or the bars may become dense.
Chill the Dough:
Cover the dough and refrigerate it for 20 minutes. This firms up the dough making it much easier to handle and press evenly into the pan.
Press the First Layer into the Pan:
Remove half of your chilled dough (approximately 348 grams). Press this evenly into the bottom of the prepared baking pan.
Freeze the First Layer:
To keep the layers distinct, lift the parchment with the dough layer from the pan and place it on a baking sheet. Freeze this layer while preparing the rest.
Prepare Second Layer in Pan:
Replace the parchment paper strips inside the pan. Take the remaining dough and press it evenly into the pan again.
Add the Filling:
Spread the strawberry preserves evenly over this second layer of cookie dough.
Top with First Layer:
Peel the parchment paper off the frozen dough layer and carefully lay it on top of the preserves. Gently press to seal.
Bake:
Place the pan in the preheated oven and bake for 25 to 28 minutes or until the top turns a beautiful golden brown.
Cool Fully:
Remove the bars from the oven and let them cool completely on a wire rack.
Invert Bars:
Use the parchment edges to lift the bars out of the pan and flip them upside down so the cookie bottom becomes the top.
Make the Glaze:
Whisk powdered sugar with whole milk and vanilla extract until smooth and pourable but not too thin.
Glaze and Decorate:
Pour the glaze evenly over the cooled bars and sprinkle with rainbow sprinkles immediately so they stick.
Set and Serve:
Let the bars sit at room temperature for one to two hours to allow the icing to set. Cut into 15 bars and enjoy!

Storage Tips

Store these bars in an airtight container at room temperature for a few days. For freshness beyond that, refrigeration works well but bring to room temperature before serving to soften the glaze and cookie If freezing, wrap tightly and thaw completely before glazing.

Ingredient Substitutions

You can swap out strawberry preserves for raspberry, apricot, or any jam you prefer For dairy-free versions, use margarine or coconut oil instead of butter and a plant-based milk for the glaze Vanilla bean paste can be replaced with vanilla extract but the paste adds a lovely little speckled look.

Serving Suggestions

These bars pair wonderfully with a scoop of vanilla ice cream or a cup of hot tea or coffee. They make festive treats for birthdays, school parties, or just a fun weekend bake.
