How to Make Buttercream Rainbow Cookies
-
Prep Cookie Dough: In a medium bowl, whisk together all-purpose flour, baking powder, and fine sea salt until well combined. In a separate bowl, cream the unsalted butter and granulated sugar together until fluffy and light in color. Add the egg and vanilla bean paste, mixing until combined. Gradually add the dry ingredients, folding in the rainbow sprinkles to finish off the dough.
-
Chill Dough: Once your dough is ready, form it into discs, wrap them in plastic wrap, and place them in the fridge to chill for at least 1 hour. This will help the cookies retain their shape during baking.
-
Shape Cookies: After chilling, roll the dough out on a lightly floured surface to a thickness of about 1/8 to 1/4 inch. Use your heart-shaped cookie cutter to cut out the cookies, and don’t forget to create smaller heart cutouts for topping!
-
Freeze Cookies: Place the cut-out cookies onto a baking tray and pop them in the freezer for about 15 minutes. This step helps prevent spreading, ensuring your cookies hold their adorable shape.
-
Bake Cookies: Preheat your oven to 350°F (176°C). Bake the cookies for 12-15 minutes, or until they’re lightly golden around the edges. Allow them to cool completely on a wire rack before frosting them.
-
Prepare Buttercream: In a mixing bowl, whip the room-temperature unsalted butter until it’s light and fluffy. Gradually mix in the confectioner’s sugar, alternating with milk, until you reach your desired frosting consistency. Add vanilla extract and mix. Divide the buttercream into portions and color with gel food coloring to create the vibrant rainbow effect.
-
Assemble Cookies: Take a solid heart cookie and generously pipe the rainbow buttercream onto its top. Next, place the smaller heart cutout on top as a beautiful garnish. Enjoy right away or store in an airtight container.
Optional: Sprinkle extra rainbow sprinkles on top for an added touch of fun!

Expert Tips for Buttercream Rainbow Cookies
- Chill Dough Effectively: Make sure your cookie dough is well-chilled to prevent spreading during baking. A properly chilled dough holds its shape beautifully!
- Check Butter Temperature: Use softened unsalted butter for the buttercream, but not too melted. This creates the fluffy texture you want for the frosting.
- Frosting Consistency: If your buttercream is too thick, add a little more milk; if it’s too thin, mix in extra confectioner’s sugar. Aim for smooth spreadability!
- Sprinkle Selection: Choose your rainbow sprinkles thoughtfully. Some types may bleed color into the dough; opt for high-quality, colorfast sprinkles for the best results.
- Freeze for Better Shape: Don’t skip the freezing step after cutting out cookies; it’s essential for maintaining those cute heart shapes during baking.

Buttercream Rainbow Heart Cookies Recipe FAQs
How do I choose the best ingredients for my cookies?
Absolutely! For the best results, choose all-purpose flour that is fresh and has been properly stored away from humidity. When selecting your baking powder, make sure it’s recent, as expired powder won’t give your cookies the rise they need. Also, opt for unsalted butter at room temperature to ensure it creams evenly with the sugar, providing that tender texture.
How should I store my Buttercream Rainbow Cookies?
Very simple! Store your cookies in an airtight container at room temperature for up to 3 days to maintain their freshness. If you’re looking to keep them for a longer time, place them in the refrigerator, where they’ll stay good for up to a week. Remember to seal them well to avoid drying out!
Can I freeze Buttercream Rainbow Cookies?
Yes, you can! For freezing, I often recommend baking the cookies without frosting. Place the cooled cookies in a single layer on a baking sheet and freeze them for about 2 hours until solid. Then transfer them to a freezer-safe bag or container and freeze for up to 3 months. When you’re ready to enjoy them, just thaw at room temperature and frost to your heart’s content!
What if my buttercream is too thick or thin?
If you find that your buttercream is too thick, simply add a teaspoon of milk at a time to achieve the desired consistency. On the flip side, if it’s too thin, mix in more confectioner’s sugar until it thickens up. Aim for a smooth, spreadable texture, perfect for piping onto your delightful cookies!
Can I make these cookies vegan-friendly?
Absolutely! You can easily substitute the egg with a flax egg—just mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water and let it sit for about 5 minutes before using. Replace the unsalted butter with a vegan butter alternative and you’re set to whip up a batch of Buttercream Rainbow Cookies suitable for vegan diets. Enjoy baking without compromising on flavor!
What should I do if my cookies spread in the oven?
If your cookies spread more than you’d like during baking, it’s likely because the dough wasn’t chilled enough! Make sure to chill the dough thoroughly before rolling it out and cutting your shapes. If you find they spread anyway, you can also chill the cutouts on the baking tray for about 15 minutes before baking to help maintain their shape. Happy baking—these heart-shaped beauties are worth the extra care!
