Ingredients
- 1 package (16.5 ounces) refrigerated sugar cookie dough
- 1 container (16 ounces) prepared vanilla frosting
- 3 tablespoons rainbow sprinkles
These three ingredients create a colorful, frosted sugar cookie dessert without making dough or frosting from scratch.
Instructions
Step 1: Prepare the Baking Pan
Preheat your oven to 350°F (175°C).
Line a 9-by-13-inch baking pan with parchment paper, leaving some overhang along the sides. Lightly grease the parchment if needed.
Step 2: Press the Cookie Dough
Remove the refrigerated sugar cookie dough from its package.
Break it into smaller pieces and distribute them evenly across the prepared pan. Press the dough firmly with clean hands or the bottom of a measuring cup until it forms an even layer.
Make sure the dough reaches the corners of the pan.
Step 3: Bake the Cookie Bars
Place the pan in the preheated oven and bake for approximately 15–20 minutes.
The edges should be lightly golden, and the center should look set. Avoid overbaking because the bars will continue to firm up as they cool.
Remove from the oven and allow the cookie base to cool completely in the pan.
Step 4: Add the Frosting
Once the cookie base is completely cool, spread the prepared vanilla frosting evenly over the surface.
Use an offset spatula or the back of a spoon to create a smooth layer.
Step 5: Decorate and Slice
Sprinkle rainbow sprinkles generously over the frosting.
Allow the frosting to set slightly before lifting the cookie slab from the pan using the parchment paper.
Cut into squares or rectangles and serve.
Helpful Tips for the Best Sugar Cookie Bars
Use chilled dough: Refrigerated dough is easier to handle and helps the bars maintain their shape.
Press evenly: A level cookie layer ensures that the edges and center bake at the same rate.
Do not overbake: The cookie base should remain soft and tender. Remove it once the center is set.
Cool completely before frosting: Warm cookie bars will melt the frosting and make decorating difficult.
Use a sharp knife: Wipe the knife between cuts for neat bakery-style squares.
Easy Variations
These optional decorating ideas make the recipe easy to customize:
- Birthday cookie bars: Use colorful rainbow sprinkles and vanilla frosting.
- Christmas version: Choose red and green sprinkles.
- Valentine’s Day bars: Use pink frosting and heart-shaped sprinkles.
- Chocolate frosting: Replace vanilla frosting with prepared chocolate frosting.
- Pastel cookie bars: Use pastel sprinkles for baby showers or spring celebrations.
These are optional substitutions and decorating ideas; the basic recipe remains three ingredients.
What to Serve with Lofthouse Sugar Cookie Bars
These sweet cookie bars pair beautifully with:
- A cold glass of milk
- Hot chocolate
- Coffee or tea
- Vanilla ice cream
- Fresh strawberries
- A dessert platter of brownies and mini cookies
They are especially lovely served as part of a birthday or holiday dessert table.
Storage Instructions
Room temperature: If your frosting is shelf-stable and the package directions allow it, store the bars in an airtight container for up to 2 days in a cool place.
Refrigerator: For longer storage, refrigerate in an airtight container for up to 5 days. Let the bars sit at room temperature briefly before serving for a softer texture.
Freezer: Freeze unfrosted cookie bars for up to 2 months. Thaw completely before adding frosting and sprinkles. Frosted bars can also be frozen in a single layer until firm, then stored in a freezer-safe container.
Frequently Asked Questions
Are these exactly like traditional Lofthouse cookies?
They are inspired by the soft, frosted bakery cookies, but they are a shortcut bar version. They have a similar sweet flavor and tender texture without requiring homemade cookie dough.
Can I use homemade sugar cookie dough?
Yes. You can use your favorite sugar cookie dough, but baking time may vary depending on the recipe and thickness.
Can I use cream cheese frosting?
Yes. Prepared cream cheese frosting makes a delicious alternative, although the flavor will be slightly tangier.
Why should the cookie base cool completely?
Frosting a warm cookie base can cause the frosting to melt, become runny, and absorb into the cookies. Cooling helps keep the frosting smooth and distinct.
Can I make these cookie bars ahead of time?
Absolutely. Bake the cookie base a day ahead, let it cool, and store it covered. Frost and decorate before serving or prepare the finished bars and refrigerate them.
How do I get clean slices?
Chill the frosted bars briefly until the frosting is firm, then use a sharp knife. Wipe the blade clean between cuts.
