Healthy Chocolate Avocado Yule Log – No Refined Sugar
Christmas yule logs! It was during a Christmas Eve at our friends’ place in Alsace that we discovered their family tradition: making a homemade yule log together on the morning of the 24th. The kids were excited, the kitchen smelled amazing with chocolate and cinnamon… But after eating the traditional super-sugary yule log, we were all crashed on the couch with a terrible sugar slump! The next year, we created our healthy version, and guess what? Nobody could tell the difference! Even grandma asked for the recipe.
So, ready for a yule log that won’t make you feel guilty? Get out your whisks—let’s show you how!

How Long Does It Take to Make This Recipe?
This recipe takes 30 minutes to prepare and 12 minutes to bake, plus 2 hours refrigeration, for a total of 2h45. But the result is absolutely worth it!
Step-by-Step Instructions:
Step 1: Prepare the Cake
Preheat your oven to 180°C (350°F). Line a 30x40cm baking sheet with parchment paper—this is essential for rolling the cake without it cracking! In a large bowl, separate the egg whites from the yolks. Beat the yolks with 60g coconut sugar until the mixture becomes pale and fluffy (about 3 minutes with an electric mixer). Add the vanilla extract. In another bowl, sift together the almond flour and cocoa powder, then gently fold them into the yolk mixture.
Step 2: Whip the Egg Whites
In a perfectly clean and dry bowl (this is crucial!), beat the egg whites with a pinch of salt. Start at medium speed, then gradually increase. When the whites start to foam, add the remaining 20g coconut sugar little by little. Continue beating until you get stiff, glossy peaks—when you turn the bowl upside down, they shouldn’t move! This step is what makes the cake light and fluffy.
Step 3: Fold and Bake
Gently fold the whipped egg whites into the chocolate mixture in three additions. Use a spatula and make upward motions to avoid deflating the whites—we want to keep all that air! Don’t overmix; a few small white streaks are OK. Pour the batter onto the prepared baking sheet and spread evenly with a spatula. Bake for 10-12 minutes—the cake should be cooked but still soft. It shouldn’t crack when you press gently on it.
Step 4: Roll the Cake
This is the tricky step! As soon as it comes out of the oven, place a clean, slightly damp kitchen towel over the cake. Quickly flip the baking sheet to unmold the cake onto the towel. Gently remove the parchment paper. Roll the cake with the towel inside while it’s still warm—start from the short side. Let it cool completely in the rolled position (about 30 minutes). This step “teaches” the cake to stay rolled without cracking!
Step 5: Prepare the Magic Ganache
While the cake is cooling, prepare your secret ganache! Cut the avocados in half, remove the pit, and scoop out the flesh. In a blender or food processor, blend the avocados with the warm melted chocolate, maple syrup, cocoa powder, vanilla, and almond milk. Blend until you get a perfectly smooth, uniform cream—it should look like chocolate mousse! Taste and adjust sweetness if needed. Set aside one-third of the ganache for the outer frosting. Refrigerate for 15 minutes so it firms up slightly.
Step 6: Assemble the Yule Log
Gently unroll the cooled cake. Spread two-thirds of the ganache over the entire surface of the cake, leaving a 2cm border. Don’t put too much ganache or it will overflow when you roll! Roll the cake again, this time without the towel, rolling tightly. Place the yule log on a serving platter, seam side down. Spread the remaining ganache on the outside of the log with a spatula.
Step 7: Create the Bark Effect
With a fork, create ridges in the ganache to mimic tree bark—make irregular horizontal lines. For an even more realistic effect, you can cut a small diagonal slice from one end and stick it on the side with ganache to make a wood “knot.” Refrigerate for at least 2 hours, ideally 4 hours or overnight.
Step 8: Decorate and Serve
Just before serving, decorate your yule log with fresh raspberries, cranberries, a few fresh mint leaves, and crushed pistachios. If you want the snowy effect, very lightly dust with powdered sugar (but it’s optional). Remove the log from the fridge 15 minutes before serving so the ganache is creamy. Cut into slices with a sharp knife. And there you have it, your healthy yule log is ready to impress!
Pro Tip: Make-Ahead
You can prepare this yule log up to 2 days ahead! Store it in the refrigerator well covered. Only decorate at the last minute so the fruit stays beautiful. It also freezes very well (up to 1 month)—thaw in the fridge the night before. Perfect for stress-free holidays!
Key Ingredients & Substitutions
Avocado
Avocado is the secret to this ultra-creamy ganache without cream! It brings a silky texture and healthy fats, and trust us, you absolutely can’t taste it. If you really don’t have any, replace with coconut cream (the thick part of a can of refrigerated coconut milk), but the texture will be different.
Almond Flour
Almond flour makes the cake moist and adds protein. You can replace it with hazelnut flour for a stronger flavor, or with half whole wheat flour, half cornstarch (but the cake will be less protein-rich).
Coconut Sugar
Coconut sugar has a lower glycemic index than white sugar. You can replace it with cane sugar, xylitol (reduce the amount by 20%), or even maple syrup (but reduce the liquid elsewhere). For a keto version, use erythritol.
Dark Chocolate 70%
Choose good dark chocolate at 70% minimum—it’s the flavor base! The darker it is, the less sweet. You can go up to 85% if you like bitterness. For a no-chocolate version (why?!), try a berry purée ganache.
Almond Milk
Any plant-based milk works—almond, oat, soy, coconut. Even cow’s milk if you’re not vegan. It’s just to adjust the ganache consistency.
VARIATIONS & CUSTOMIZATIONS
Black Forest Version
Add 200g pitted cherries (fresh or thawed frozen) between the cake and ganache. Chop them roughly and drain well. Add 1 tablespoon kirsch (optional) to the ganache. Decorate with fresh cherries and chocolate shavings. This is our favorite version for adults!
Praline-Hazelnut Yule Log
Replace the almond flour with hazelnut flour in the cake. Add 3 tablespoons hazelnut butter (100%) to the ganache. Decorate with caramelized crushed hazelnuts. For Nutella fans, this is heaven in healthy version!
Strict Gluten-Free Version
Replace the almond flour with 40g rice flour + 20g cornstarch. The cake will be slightly less moist but still delicious. Make sure all your ingredients (cocoa, chocolate) are certified gluten-free.
Coffee-Chocolate Yule Log
Add 2 tablespoons instant coffee dissolved in 1 tablespoon hot water to the ganache. Lightly brush the cake with a coffee-maple syrup mixture before filling. Decorate with chocolate-covered coffee beans. For tiramisu lovers, it’s a delight!
FREQUENTLY ASKED QUESTIONS
Why Does My Cake Crack When I Roll It?
Several reasons: either it’s overcooked (it should stay soft), or you let it cool flat instead of rolling it warm, or you overmixed the batter and deflated the whites. The trick: always roll the cake while it’s still warm with the towel, and unroll it only when completely cool.
Can You Really Not Taste the Avocado?
Promise! The chocolate and cocoa completely mask the avocado taste. What it brings is just an incredibly creamy texture and healthy fats. We’ve served this yule log dozens of times and nobody has ever guessed there was avocado in it. Even kids love it!
How Long Does This Yule Log Keep?
In the refrigerator, it keeps for 3-4 days in an airtight container or well covered. The avocado ganache doesn’t turn brown thanks to the chocolate protecting it from oxidation. In the freezer, it lasts 1 month—perfect for preparing ahead! Thaw in the fridge 6-8 hours before serving.
Is It Really Healthier Than a Traditional Yule Log?
Yes! A traditional yule log contains about 400-500 calories per serving with lots of refined sugar and cream. Our version is about 250-300 calories, with natural sugars with lower glycemic index, healthy fats from avocado and almonds, and antioxidants from dark chocolate. Plus, it’s high in fiber!
My Egg Whites Won’t Whip, Why?
That’s frustrating! Common reasons: a bit of yolk in the whites, a greasy or wet bowl, or eggs that aren’t fresh enough. Make sure your bowl and whisk are perfectly clean and dry. A drop of white vinegar or lemon juice can help the whites whip. And beat, beat, beat—it takes a good 5-7 minutes!
