This moist and fluffy Lemon Blueberry Coffee Cake is the perfect spring breakfast or dessert for the whole family. It’s light and fluffy and has a fresh taste of tangy lemons and juicy blueberries.
This lemon blueberry coffee cake recipe is also Paleo, Gluten-Free, Grain-Free, and can be made Keto as well.
You might have noticed that I have been loving the lemon and blueberry flavor combination lately as spring is in full force and summer is just right around the corner.
Don’t worry, I’ll probably go back to everything peanut butter and chocolate soon. But right now, so many of you requested a lemon blueberry combo!
I actually made another gluten-free coffee cake recipe a few months ago and I got asked so many times “where is the coffee?”
And believe it or not, coffee cake doesn’t have to have any coffee in it! It just simply got its name because it pairs well with a cup of coffee.
However, what is important for a coffee cake is the crumbly streusel on top.
Lemon Blueberry Coffee Cake that is good for you
Yes! This gluten-free lemon blueberry cake is a healthier version of the original coffee cake. I have made some substitutions to be able to make this cake a little healthier.
Coconut oil contains healthier fats than regular butter, and it’s the easiest way to make baked goods dairy-free.
I also love baking with coconut oil because it helps to keep the cake moist while not adding much flavor.
Not only does almond flour provide a delicious nutty flavor, but it also has way more fiber and nutrients compared to white wheat flour.
Using almond flour and tapioca flour also makes this healthy dessert gluten-free, paleo, and keto-compliant.
Blueberries are known for being a super-food! They are packed with vitamin C and Antioxidants. You can read more about blueberries’ health benefits here.
Ingredients for a perfect crumble topping
A must for any type of coffee cake is the crumbly streusel on top.
And let me tell you, I am addicted! This crumble topping is SO good and you can probably add it to any cake to make it extra special.
Crumble topping ingredients
Adds a nutty flavor and extra protein and nutrients
The good kind of fat, with a mildly sweet flavor
Coconut sugar (or keto-friendly granular sweetener)
I love baking with coconut sugar. The flavor reminds me of regular light brown sugar, but it’s better for you
Make sure you get organic lemons since you are using the skin. And always wash and dry your lemons, even when you get organic once
Ingredients for the best Lemon Blueberry Coffee Cake recipe
To make this soft and moist healthy lemon blueberry cake you will need these wholesome ingredients:
Use room temperature eggs to make sure that the batter will blend evenly.
It will also allow the cake to get fluffier and rise evenly.
I love the rich almost caramel flavor that the brown sugar adds to this lemon blueberry coffee cake.
I am using a Keto-friendly brown sugar, but if you would like you can use regular brown sugar or coconut sugar.
You know I love baking with coconut oil.
It keeps the cake moist and the neutral flavor is perfect when you don’t want to over-power the lemon and blueberry flavor.
Using oil when baking also makes the cake dairy-free. Make sure you melt and cool the coconut oil before mixing it with the other ingredients.
Always freshly squeezed!
You don’t need much juice to give this cake a fresh and tangy flavor, but whatever you do, don’t skip it! It complements the blueberries so well!
Vanilla is kind of like the salt of baking.
You might not notice it when it’s there but you will know something is missing if you forget to put it in.
It also enhances all the other flavors and makes everything more delicious.
Almond flour might be my favorite flour to bake with. It adds extra moisture, protein, and healthy fats.
It also has a delicious nutty flavor, perfect for this healthy lemon blueberry cake!
Almond flour is also perfect if you want to make your baked goods gluten-free, Paleo and Keto-friendly.
Tapioca flour has become one of my most used ingredients over the past few years.
I love it as a thickening agent for soups and sauces and when used in baking, it adds a slightly chewy texture, perfect for this coffee cake!
For this recipe, I’m using baking soda as my rising agent.
Baking soda needs acid to become activated, which – you guessed it – the lemon provides.
I love using the zest when making anything with citrus. It’s so fragrant and flavorful without adding too much sour juice.
Also, zest before you squeeze the juice out! Believe me, I have done it the other way around more than once. It’s way more difficult than it has to be…
Fresh or frozen doesn’t matter, whatever you got on hand.
Blueberries are a favorite in my kitchen, so juicy and flavorful, and packed with nutrients such as antioxidants and vitamin C.
A note on sugar substitution:
You can use other types of sugar to fit your diet and what you have on hand.
If you are using anything besides the Keto-friendly brown sugar I’m using, the color might be different from my coffee cake in the pictures.
- Coconut sugar – a great Paleo option; however, it’s not Keto-friendly
- Maple sugar – a great Paleo option
- Monk Fruit Sweetener – Keto and Paleo-friendly
How to make a Gluten-free Lemon Blueberry Coffee Cake
Start with making the crumble topping for the Lemon Blueberry Coffee Cake so it can chill in the fridge while preparing the rest of the cake.
Also, here is your reminder to take out your eggs from the fridge if you haven’t already.
First, wash and dry the lemons. Zest. Be careful not to get any of the white bitter parts of the peal.
Then, in a small bowl, mix together almond flour, coconut oil, coconut sugar, and lemon zest for the crumble topping.
Store the crumble mixture in the fridge while you’re preparing the cake batter.
Now, juice the already zested lemons. You will need one or two lemons depending on size.
Then, in a large mixing bowl, whisk together the wet ingredients: eggs, brown sugar, melted and cooled coconut oil, lemon juice, and vanilla extract.
In a separate bowl, whisk together the dry ingredients: almond flour, tapioca flour, and baking soda.
Whisk until there are no clumps left and everything is evenly distributed.
Then, gently add the dry ingredients to the wet mixture and carefully combine with a spatula.
In a separate small bowl, toss the blueberries in tapioca flour.
Then, fold in the blueberries and lemon zest into the cake batter. Be careful not to over-work the mixture.
Pour the cake batter into an 8×8 parchment-paper-lined baking dish.
Spread an even layer of the lemon sugar crumble on top.
The crumble mixture should have hardened slightly while in the fridge. Use your hands to combine smaller crumbles together to create larger pieces.
Bake in the middle of the oven at 350 F for about 35 minutes until a toothpick comes out clean.
Let the lemon blueberry coffee cake completely cook before glazing with Maple Coconut Butter.
Tips for perfecting this gluten-free lemon blueberry cake
- Toss blueberries in 1 – 2 tsp tapioca flour before folding into the batter to prevent sinking to the bottom. Believe me, I have made so many batches of the blueberry muffins and learned this trick!
- Make sure your oven temperature is right using an oven thermometer! You would be surprised to know how often the actual temperature differs from what is displayed.
- Always use room-temperature eggs when baking to make sure they blend evenly. It also will allow the cake to rise more evenly.
- Check the lemon blueberry coffee cake with a toothpick around 30 – 32 minutes or once the top/edges start to brown. You don’t want to risk over-baking since it could result in a hard outside and a dry inside.
This is how I love serving my healthy lemon blueberry coffee cake
- I love serving my coffee cake with a Maple Coconut Butter Glaze! Just melt 3 tablespoons of coconut butter and stir it together with 1 tablespoon of maple syrup. Drizzle on top!
- Ice cream!! This Lemon Blueberry Coffee Cake would be amazing with vanilla ice cream.
- For a yummy breakfast treat, serve with some thick yogurt and your favorite nut butter.
- And of course, it’s a Coffee Cake, let’s serve it with coffee! Most of the time I drink my coffee with just a little bit of foamy oat milk. But here are two of my coffee drink recipes that you might want to try out: Whole30 Mocka Latte and Vegan Pumpkin Spiced Latte.
How to store this healthy lemon blueberry coffee cake
If you, for some reason, won’t finish the whole Lemon Blueberry Coffee Cake in one sitting, don’t worry! It keeps well for a while.
You can actually keep it on the countertop, wrapped in plastic or in an airtight container, for 2-3 days. Or keep it in the fridge for up to 5 days.
And yes, it freezes very well as well!
I would recommend slicing and wrapping each piece individually before freezing. This will allow you to grab one piece at a time from the freezer, instead of having to defrost the whole thing.
This is an awesome hack for a quick and easy breakfast or late-night dessert. To reheat, warm in the microwave for 15 seconds.
