Pale cake-flour sugar cookies with a fine fluffy crumb, pastel-blue buttercream and cheerful rainbow sprinkles.
The important detail in this recipe is the way the dough is shaped and finished. Scoop about 43 g, roughly 2½ tablespoons, and flatten into rounds about ⅓ inch thick and 2½ inches across. Space 3 inches apart. These are puffy frosted cookies, not thin cut-outs.
Before mixing, measure the flour without packing it and prepare the pans. Cake flour has lower protein and gives the fine, soft crumb. All-purpose flour produces a denser cookie; use cake flour and stop mixing once no dry patches remain.
Watch the first tray closely near the end of the baking range. Let the cookies cool completely before finishing: Beat frosting butter smooth, add confectioners’ sugar on low, then milk, vanilla and salt. Beat until creamy; tint with a tiny drop of optional blue gel color. Spread onto completely cooled cookies and add rainbow sprinkles.

Instructions
Mixing
- Make the doughBeat butter, full-fat margarine and dough confectioners’ sugar until airy and pale. Mix in egg and extracts. Whisk cake flour, cornstarch, leaveners, cream of tartar and salt; add on low just until combined.
Thermal management
- Manage the doughCover and refrigerate for 120 minutes.
Shaping
- Shape evenlyScoop about 43 g, roughly 2½ tablespoons, and flatten into rounds about ⅓ inch thick and 2½ inches across. Space 3 inches apart. These are puffy frosted cookies, not thin cut-outs.
Baking
- Bake one tray at a timePreheat to 375°F (190°C). Bake on the center rack for 8–9 minutes. Edges should be set and only lightly colored; centers must lose their wet sheen. Use cool pans for subsequent trays.
Cooling
- Let the crumb setRest on the pan for 5 minutes, then transfer to a rack and cool completely, about 30 minutes total, before frosting.

Chef’s Science & Pro Tips
Choose cake flour
Cake flour has lower protein and gives the fine, soft crumb. All-purpose flour produces a denser cookie; use cake flour and stop mixing once no dry patches remain.
Keep the portion consistent
Scoop about 43 g, roughly 2½ tablespoons, and flatten into rounds about ⅓ inch thick and 2½ inches across. Space 3 inches apart. These are puffy frosted cookies, not thin cut-outs. Different thicknesses need different baking times; bake comparable pieces together.
Use the finish as your cue
Look for a set surface and lightly colored edges rather than a dark golden top. Overbaking dries the center; let the cookies finish setting on the pan.
Storage & Make-Ahead
| Method | How long | What to do |
|---|---|---|
| Room temperature | Up to 1 day | Keep frosted cookies covered in a cool room. If the room is warm, refrigerate them promptly instead. |
| Refrigeration | Frosted cookies: up to 4 days | Refrigerate in a sealed container; bring out only the portion you will serve and let the frosting soften briefly. |
| Freeze raw | Up to 2 months | Freeze portioned dough balls on a tray, then seal in a freezer bag. Bake from frozen, allowing extra time and checking for a set center. |
| Freeze baked | Up to 2 months | Freeze unfrosted cookies for up to 2 months, then thaw sealed and frost. This preserves a neater finish. |
| Restore | 30–60 minutes | Thaw plain cookies in a closed container and frost after thawing. Do not heat frosted cookies in the oven. |
Notes
- Use the gram weights for the most consistent dough. Small leavener weights are approximate; measure teaspoons carefully. Egg weights exclude shells. Oven temperatures refer to a conventional oven.

Frequently Asked Questions
A few helpful answers before you bake.
What texture should these cookies have?
Pale cake-flour sugar cookies with a fine fluffy crumb, pastel-blue buttercream and cheerful rainbow sprinkles. Judge the final texture after cooling, not while the centers are warm.
Can I use all-purpose flour instead?
Cake flour has lower protein and gives the fine, soft crumb. All-purpose flour produces a denser cookie; use cake flour and stop mixing once no dry patches remain.
How do I get an even batch of lofthouse-style sugar cookies?
Scoop about 43 g, roughly 2½ tablespoons, and flatten into rounds about ⅓ inch thick and 2½ inches across. Space 3 inches apart. These are puffy frosted cookies, not thin cut-outs. Bake one test tray and check the stated doneness cues; thicker portions need more time than thinner ones.
