Smart prep strategies before you begin
- Measure flour by spooning into the cup and leveling for accurate texture.
- Soften butter at room temperature so it creams smoothly with sugar.
- Line the baking pan with parchment to lift bars easily.
- Make the frosting while bars cool to save time.
Complete ingredient list
1 c. butter (softened at room temperature), 2 c. sugar, 4 eggs, 2 tsp. vanilla, 1 tsp. salt, 1/2 tsp. baking soda, 5 c. flour, 5 c. powdered sugar, 1 c. butter (softened at room temperature), 1/4 – 1/2 tsp. almond extract, 6 Tbsp milk, green food coloring, St. Patrick’s Day sprinkles
Helpful notes on ingredients and swaps
If you want to reduce refined sugar or try a different crumb, consider these swaps and quality tips:
- Swap half the all-purpose flour with whole wheat pastry flour for nuttier flavor and denser texture.
- For a lower-sugar option in other recipes you enjoy, try techniques used in sugar-free chocolate chip cookies.
- Use real vanilla extract for the best aroma; almond extract is optional but only a little goes a long way.
- Choose good-quality butter for richer flavor—European-style butter will make a softer, more tender bar.
Baking and frosting directions
Sugar Cookie Bars Instructions:
- Preheat the oven to 350°F (175°C). Line a 9×13-inch pan with parchment and set aside.
- In a large bowl, cream 1 c. butter (softened at room temperature) with 2 c. sugar until light and fluffy, about 2–3 minutes.
- Beat in 4 eggs, one at a time, then mix in 2 tsp. vanilla and 1 tsp. salt until combined.
- In a separate bowl, whisk together 1/2 tsp. baking soda and 5 c. flour. Gradually add dry ingredients to the wet mixture and mix until just combined—do not overmix.
- Press the dough evenly into the prepared pan, smoothing the top with an offset spatula.
- Bake 18–25 minutes, or until the edges are lightly golden and a toothpick inserted near the center comes out mostly clean. Remove from oven and cool completely in the pan.
Frosting Instructions:
- In a medium bowl, beat 1 c. butter (softened at room temperature) until creamy. Gradually add 5 c. powdered sugar, mixing on low until combined.
- Add 1/4 – 1/2 tsp. almond extract (optional) and 6 Tbsp milk, adjusting milk to reach a spreadable consistency.
- Tint frosting with green food coloring to desired hue. Spread evenly over cooled bars.
- Decorate with St. Patrick’s Day sprinkles, slice into bars once the frosting sets, and serve.
Oven times and visual cues to watch for
- Center doneness: bars should be set and only very slightly springy in the center when gently pressed.
- Edge color: look for just a hint of golden brown around the edges for a chewy interior and firmer rim.
- Frosting texture: if the frosting looks glossy and spreads smoothly, it’s the right consistency; add more powdered sugar to thicken or a teaspoon of milk at a time to thin.
Best ways to present and enjoy these bars
These bars work well on dessert platters, as classroom treats, or boxed for neighbors. For celebrations, add themed decorations like gold-foil candies or shamrock sprinkles.
Serving suggestions
- Serve with a hot cup of coffee or a cold glass of milk
- Pack into treat bags for school parties or bake sales
- Cut smaller squares for buffet-style serving at gatherings
- Use as a base for an ice cream sandwich with mint ice cream
Storing, freezing, and reheating guidance
Store these bars at room temperature covered for up to 3 days, or refrigerate for up to a week. Freeze uncut bars or frosting separately for up to 3 months.
Short storage reminders
- Wrap tightly with plastic or place in an airtight container to prevent drying
- Thaw frozen bars in the refrigerator overnight before serving
- To refresh chilled bars, warm briefly in a 300°F oven for 5–7 minutes
Helpful tools and time-saving techniques
A few tools make assembly easier: an electric mixer for creaming, an offset spatula for smoothing, and a bench scraper for cleaner cuts.
Extra technique tips
- Chill the dough briefly if it’s too soft to press evenly into the pan
- Use parchment overhang to lift bars from the pan cleanly
- Clean frosting edges with a warm knife for professional-looking slices
Flavor twists and dietary alternatives
You can make simple swaps for flavor or dietary needs without changing the overall method.
Quick swap ideas
- For gluten-free: substitute a 1:1 gluten-free flour blend for the all-purpose flour.
- Lower sugar: reduce granulated sugar slightly or experiment with natural sweeteners, keeping in mind texture changes.
- Dairy-free: use vegan butter and a non-dairy milk for the frosting.
- Add-ins: fold in 1 cup of mini chocolate chips or chopped nuts into the dough for variety.
Nutrition snapshot per serving
Estimated per serving (1 bar, assuming 24 bars from the pan): Calories ~420, Protein ~3–4 g, Fat ~20–25 g, Carbohydrates ~50–60 g. These values are approximate and will vary by portion size and brands used.
Nutrition adjustment notes
- To lower calories, cut bars into smaller portions or reduce added sugar in the dough by up to 25% and adjust frosting thickness.
- Swap half the butter in the frosting with a neutral oil-based spread to slightly reduce saturated fat (note: texture will change).
- Use lower-calorie milk alternatives to shave a few calories per serving.
Quick answers to common reader questions
Q: Can I make these bars ahead of time?
A: Yes. Bake and frost as directed, then store in an airtight container for up to 3 days at room temperature or freeze for up to 3 months.
Q: My frosting is too thin—how do I thicken it?
A: Gradually add more powdered sugar a quarter cup at a time until it reaches spreadable yet thick consistency; chilling briefly will also help.
Q: Can I bake these in a different size pan?
A: You can use a 9×13-inch pan for the stated bake time; for a smaller pan the bars will be thicker and need a bit longer to bake—monitor doneness and adjust time accordingly.
Q: How do I keep sprinkles from bleeding color?
A: Use decorations that are labeled “non-bleeding” or add sprinkles just before serving to minimize color transfer.
