Keto Funfetti Birthday Cake Bars

These Keto Funfetti Birthday Cake Bars are such a fun keto dessert.

They are gluten free, sugar free and taste DELICIOUS! You'd never know they were healthy..

They pretty much make the perfect excuse to eat a slice of cake for breakfast.

These keto cake bars are made using almond flour and coconut flour for the base, this combination provides the best texture and flavour in many keto desserts. I also add a tiny bit of arrow root starch and xanthan gum to improve the texture even more!

I really feel like I nailed it down with these bars!  The cake is so light and soft while also being super moist (ya I said it) and flavourful.

Plus, to top it off we add a layer of sugar free cream cheese frosting. Then both the base of the cake and the top gets plenty of sprinkles added to it (which obviously makes everything better).

And these are no ordinary sprinkles.. Stoka Nutrition makes these awesome sugar free sprinkles that you can use in keto baking! They have become my new obsession. So don't be confused when you start to notice sprinkles in all of my desserts…..

If you want to purchase your own sprinkles, they were kind enough to give me a discount code. I don't receive any commission from this so it's purely for you guys!

Alright, back to the recipe!

Ingredients You'll Need To Make Keto Funfetti Birthday Cake Bars

• • Almond Flour
  • Coconut Flour
  • Xanthan Gum
  • Powdered Monkfruit/Erythritol Sweetener 
  • Arrow Root Starch
  • Keto Friendly Sprinkles

Tools You'll Need To Make Keto Birthday Cake Bars

• Food Scale (optional but this is my favourite food scale, literally lasts a year on one set of batteries, I've had mine for ~4 years now and it's never once let me down, PLUS it will give you nutrition facts for tons of food items based on their weight and you can even add your own)
• Spatula
• Stand Mixer (optional, I use this for everything! Breads, muffins, cookies, definitely love my Kitchaid mixer!)
• Hand Held Beaters (These will be especially necessary if you do not have a stand mixer)
• 9×9 inch pan

Tips For Making Keto Funfetti Cake Bars

• When making these, you'll notice the cake browns more than a traditional cake. Don't freak out! You cake will not be dry. Keto desserts tend to brown a little more in terms of cakes and muffins. It's nothing to be alarmed about. The inside and even those slightly brown edges will be super soft still!
• When removing your cake from it's pan, I like to take a knife and gently run it along the sides, then kind of jiggle it around a bit until I know it's loose. Then I flip it on to a plate where I can frost the bottom (which, now becomes the top).
• When slicing these into bars, wipe your knife in between for clean cuts and no messy frosting.
• If you want, add a couple drops of food colouring to your frosting to make these bars pop even more!

Can I Still Make These Keto Funfetti Birthday Cake Bars If I Don't Have Almond Flour?

• You can try but just know that coconut flour alone has a slightly more pronounced flavour, the overall texture of the cake may also be slightly less soft as almond flour has a bit more fat in it for the amount we use.
• Use 1 cup (112g) total coconut flour for this recipe and an additional 1/2 a whisked egg if making without almond flour

Can I Still Make These Keto Funfetti Birthday Cake Bars If I Don't Have Coconut Flour?

• Again, you can try! But coconut flour adds a nice bit of “fluffiness” to the batter, the texture is really nice with both almond flour and coconut flour and helps to lower the overall calories BUT you can likely make these with almond flour alone if you wanted, they just may be a bit more dense and slightly higher in calories.
• Use 2 1/2 cups (280g) almond flour for this recipe if making it without coconut flour.

Why Do I Need Xanthan Gum And Arrow Root Starch For These Keto Cake Bars, Can I Just Make Them Without These Ingredients?

• Xanthan gum is essential to texture when it comes to gluten free and keto baking. It makes binds the flour with the liquid and prevents crumbliness..leading to more moist, soft and chewy baked goods. It's expensive but a very tiny amount goes a long way. Your one bag may last you a year or more!
• Technically you don't NEED  xanthan gum for this recipe but If you plan on doing any amount of keto baking (or even cooking as it's used in sauces as well) then I'd recommend purchasing a bag. You'll be glad you did!
• Arrowroot Starch is optional in this recipe. If you have cornstarch you can actually substitute that. But arrowroot starch simply adds a bit of a “melt in your mouth” texture to recipes. It helps things stay soft in the center and overall just creates a really nice mouth feel.

How To Store Low Carb Keto Funfetti Birthday Cake Bars

• To store these low carb cake bars, place them in an airtight container in the fridge for up to 6 days OR freeze them for a future snack.
• If you don't have a container large enough to put lay them all out flat, simply place them on a plate & put some toothpicks in the tops of some of the bars. Wrap with Saran Wrap. For freezing, just freeze them flat on a cookie sheet uncovered until the frosting is frozen, then your can place them in a ziplock with a layer or wax or parchment paper to keep them from getting freezer burnt and store them that way.
