Recipe Ingredient Notes

Gluten Free Flour: The recipe for this gluten free funfetti cookie cake is highly adaptable. I have tried it with my own blend of gluten-free flour, as well as Bob's Red Mill 1-1 and King Arthur Measure for Measure, all of which contain xanthan gum and produce excellent results. While I have not yet experimented with other blends like Cup4Cup, it's possible that they could work equally well in this recipe.

Dry Milk Powder: This is an optional ingredient. Adding dry milk powder to cookie dough is a simple way to improve your cookies' flavor, texture, and appearance. Non-fat milk powder is located in the baking section or near the canned milk in your local grocery store.

White Chocolate Chips: Look for white chocolate that is made with real cocoa butter, rather than vegetable oil, and has a high percentage of cocoa butter (at least 30%). Some popular brands of white chocolate include Valrhona, Callebaut and Ghirardelli.

Sprinkles: There are many brands of Jimmie Sprinkles that are gluten-free. But it's important to check the label before purchasing to ensure that they are certified gluten-free. I don't recommend using nonpareils since they tend to bleed into the funfetti cookie dough.

• Wilton Jimmie Sprinkles - Wilton offers a variety of gluten-free jimmie sprinkles in a range of colors.
• Fancy Sprinkles - In addition to a wide variety of sprinkle blends, Fancy Sprinkles offers individual sprinkle types, including jimmies, in a range of colors. Their jimmies are made from high-quality ingredients and are free from artificial colors and flavors. They are also gluten-free and certified kosher. (Personal Favorite)
• Sweetapolita Sprinkles - Sweetapolita offers a range of gluten-free jimmie sprinkles that are also free from artificial colors and flavors.
• India Tree Sprinkles - India Tree offers a range of gluten-free decorating sugars, sanding sugars, and sprinkles, including jimmies, made with natural colors.

How to make a Gluten Free Funfetti Cookie Cake

Making the dough for this gluten free funfetti cookie cake is very straightforward. Make sure the butter and the eggs are at room temperature. Detailed instructions how I line a 9" cake pan for cookie cakes can be found here: How to line a cake pan

Step 1: Prepare a 9" cake pan by lining it with parchment paper and set it aside. Preheat the oven to 325F. In a separate bowl sift together the gluten-free flour, cornstarch, baking powder, baking soda, kosher salt, and dry milk powder (if using).

Step 2: In a stand mixer bowl fitted with a paddle attachment or a large mixing bowl, combine room-temperature unsalted butter, light brown sugar, and granulated white sugar. Cream the mixture together at a medium speed for 2-3 minutes until it becomes light and fluffy. Halfway through the creaming process, remember to pause and scrape down the sides of the bowl.

Step 3: Add the egg, egg yolk, vanilla extract, and almond extract (if using) and mix until fully incorporated.

Step 4: Add the dry ingredients to the wet ingredients. Mix until just blended in. Add the chocolate chips and rainbow sprinkles at a low speed just to combine.

Step 5: Transfer the gluten free funfetti cookie cake batter to the prepared cake pan and press into an even layer. The easiest way to do this is using clean hands. If you like, top the dough with some additional white chocolate chips. At this point the unbaked gluten free funfetti cookie cake can be stored in the fridge up to 48hrs or frozen up to 2 months.

Step 6: Bake the cookie at 325F for 28-30 minutes until the top is golden brown and feels firm. Personally, I prefer a slightly underbaked than overbaked cookie so it will have a chewy texture. This cookie cake will deflate slightly while cooling.

Step 7: Remove the gluten-free cookie from the oven and place it on a wire rack. Allow to cool completely in the pan before frosting.

Small Batch Cream Cheese Frosting

The classic frosting for a funfetti cake is vanilla buttercream frosting but to be honest, I love a good cream cheese frosting. It has a delicious, creamy and tangy flavor that complements the sweetness of the Funfetti Cookie Cake.

Make sure the unsalted butter and the cream cheese are at room temperature. Especially the cream cheese or you will end up with lumps of cream cheese in the frosting.

Step 1: In the bowl of the stand mixer or a medium bowl combine the unsalted butter, powdered sugar and a pinch of kosher salt. Mix for 2 minutes until light and fluffy. Make sure to start the mixer at a low speed or there will be powdered sugar coating your kitchen counter.

Step 2: Add the room-temperature cream cheese and vanilla extract and beat until you have a smooth, creamy thick cream cheese frosting. Remember to use a flexible spatula to scrape the sides of the bowl, ensuring that no pockets of sugar or butter remain on the bottom of the bowl.

Step 3: Transfer the cream cheese frosting to a piping bag fitted with a standard piping tip and decorate the fully cooled Gluten Free Funfetti Cookie Cake. Top with additional Sprinkles and White Chocolate Chips. Store any leftover cream cheese frosting in the fridge in an airtight container up to 10 days (this buttercream makes a delicious topping for my Gluten Free Oreo Cookie Cake or my Gluten Free Cookie Cake Recipe)

Storage & Freezing

To keep the Gluten Free Funfetti Sugar Cookie Cake fresh, place it in an airtight container and store it for a maximum of three days. Although cream cheese frosting has sugar that acts as a preservative, it is advisable to refrigerate the cake if your kitchen is warm to prevent spoilage. It's better to be safe than sorry, so I recommend storing the cake in the fridge. If you opt-out of cream cheese frosting, you can keep the cookie cake at room temperature.

When freezing the gluten free funfetti cookie cake with frosting, use a freezer-safe container and freeze it for a maximum of one month. Thaw at room temperature when ready to eat.

To freeze the gluten-free funfetti cookie cake without frosting, take it out of the cake pan and wrap it with plastic wrap. Place it in a ziplock bag and freeze for a maximum of two months. Defrost the cake at room temperature before decorating and serving.

Note about Salt in my Recipes

I use Diamond Kosher Crystal Salt in all of my recipes unless otherwise stated. If use use a different brand or kind of salt in your kitchen please adjust accordingly since some salts can be saltier. If you use Morton’s Kosher Salt please be aware that their salt granules are smaller in size, denser, and crunchier and twice as salty.

Baking in grams

I share my recipes in grams and by weight since baking by weight is the most accurate way to bake. Digital Scales are very affordable and easy to use. You can purchase them on Amazon for less than a set of measuring cups. For small amounts under 10 grams, I like to use this Precision Pocket Scale. Measuring cups are very inaccurate which can cause significant errors when it comes to gluten-free baking or baking in general. Especially since I bake with gluten-free flours which weigh differently than “regular” flours. I do provide some ingredients like spices and leavening agents in measuring spoons. To learn more about Baking with a digital scale, make sure to check out my post about Baking by weight.

Note about Ovens and Oven Temperatures

All my recipes are tested and developed with a conventional oven. I always bake my baked goods on the rack placed in the MIDDLE of my oven. This way the heat coming from the bottom will not burn my baked goods.

If you are baking with convection (fan-forced), please adjust the recipes accordingly. Convection oven can cause baked goods to dry out quickly and still be raw inside. Since takes at least 15-20 minutes for a standard American Oven to be fully preheated. I highly recommend investing in an Oven Thermometer.

Substitutions and Modifications

Any dietary or ingredient modifications/substitutions to this recipe may alter the end result in appearance and taste. I test my recipes several times as published in this post and The Gluten Free Austrian Blog is not responsible for the outcome of any recipe you find on our website.
