These nostalgic dessert bars combine a soft, buttery sugar cookie base with sweet strawberry jam filling and a simple vanilla glaze. The crumble topping creates that classic poptart texture everyone loves.

Perfect for gatherings, lunchboxes, or afternoon treats, these bars come together quickly with just 20 minutes of prep. The homemade cookie dough is pressed into the pan, topped with jam, then dotted with remaining dough before baking until golden.

Once cooled, a quick powdered sugar glaze gets drizzled over the top and finished with plenty of colorful sprinkles for that fun, festive look. Cut into squares and enjoy this childhood favorite in bar form.

Last summer my niece grabbed a frosted pop tart from my pantry and said these should be bigger. That tiny complaint sparked a weekend experiment that turned into these bars. Now they are the most requested treat at every family gathering.

I brought these to a potluck last fall and watched three adults argue over the last corner piece. Something about that combination of buttery cookie and sweet jam takes people back to simpler moments.

Ingredients

  • Unsalted butter: Room temperature butter creates the tenderest crumb I have found
  • Granulated sugar: Cream this thoroughly with the butter for that light texture
  • Eggs: Add them one at a time to prevent the mixture from separating
  • Vanilla extract: Do not skip this, it is what makes it taste homemade
  • All-purpose flour: Measure by spooning into your cup, not scooping directly
  • Baking powder: This gives the bars just enough lift without becoming cakey
  • Salt: Even a small amount balances all that sugar beautifully
  • Strawberry jam: A seedless variety spreads more evenly across the dough
  • Powdered sugar: Sift this first to avoid any lumps in your glaze
  • Milk: Start with two tablespoons and add more to reach your desired consistency
  • Sprinkles: Add these immediately after glazing or they will not stick

Instructions

Prep your pan:
Lining with parchment paper makes cleanup effortless and helps you lift the whole batch out later.
Cream the butter and sugar:
Beat these together until the mixture looks pale and fluffy, about three minutes.
Add eggs and vanilla:
Crack each egg separately before adding to catch any shell pieces.
Mix the dry ingredients:
Whisk the flour, baking powder, and salt in a separate bowl so everything distributes evenly.
Combine the dough:
Mix on low speed until just combined, some dry streaks are better than overmixed.
Press in the base:
Use lightly floured hands to press two-thirds of the dough into the pan without sticking.
Spread the jam:
Warm the jam for 15 seconds in the microwave to make it easier to spread evenly.
Add the topping:
Crumble the remaining dough over the jam, some jam should peek through.
Bake until golden:
The edges should start turning golden while the center looks set.
Cool completely:
This step is crucial, warm bars will melt the glaze right off.
Make the glaze:
Whisk until smooth, it should pour easily but still coat a spoon.
Finish with sprinkles:
Work quickly once the glaze is on, it starts setting fast.

My brother ate three of these standing at the counter, barely pausing between bites. That is when I knew this recipe was a keeper worth making again and again.

Making Ahead

The unglazed bars keep well in an airtight container for up to three days. I usually glaze them the morning of serving for the freshest appearance.

Flavor Variations

Raspberry and apricot jams work beautifully here. My personal favorite is mixing half strawberry with half raspberry for a deeper berry flavor.

Storage Tips

Store these between layers of wax paper to prevent them from sticking together. The glaze stays fresh longer that way.

  • Room temperature is fine for two days
  • Refrigerate after that for up to a week
  • Freeze unglazed bars for up to three months
