The Perfect Lemon-Blueberry Coffee Cake | Soft and Buttery with an Irresistible Crumb Topping

There’s something about the aroma of a freshly baked coffee cake that just sets the tone for a slow, meaningful morning. And this Lemon-Blueberry Coffee Cake does exactly that—it fills the kitchen with warm, citrusy notes and that unmistakable smell of buttery crumb topping crisping in the oven. Whether it’s for a quiet weekend breakfast, a church gathering, or just a sweet snack to have on hand during the week, this coffee cake has become a staple in our home.

I’ve made a lot of breakfast bakes over the years, but this one checks every box: it’s easy to make, it holds up well for days (if it lasts that long), and every bite is loaded with juicy blueberries, bright lemon flavor, and a golden, buttery, crunchy topping.

Why This Lemon-Blueberry Coffee Cake?

This isn’t one of those dry, overly sweet coffee cakes that sits on the counter and gets picked at for a day or two. This one disappears fast. It’s moist and tender, thanks to Greek yogurt (or sour cream), and the lemon zest brings a fresh, springy flavor that cuts through the sweetness in the best way.

The blueberries bring their own natural sweetness and moisture, and whether you use fresh or frozen, they hold up beautifully in the batter. My favorite part? The crumb topping is thick, buttery, and just the right amount of crunch, made even better with a bit of Sugar in the Raw sprinkled in.

Lemon-Blueberry = Cake That Works for Any Occasion

One of the best things about this Lemon-Blueberry Coffee Cake is how versatile it is. It’s become a go-to for:
    •    Weekend breakfast with the kids
    •    Brunch with family and friends
    •    Make-ahead holiday mornings (it’s just as good the next day)
    •    Bringing to church or potlucks
    •    A little afternoon slice with coffee or tea

If you’re someone who likes to bake something once and enjoy it for a couple of days, this cake holds up really well. The crumb topping stays crisp, the blueberries don’t sink or get soggy, and the glaze (optional, but highly recommended) adds that extra touch of brightness.

Tips for the Best Lemon-Blueberry Coffee Cake

Here’s what I’ve found works best after testing a number of variations:

1. Use fresh lemon zest and juice.
   Bottled lemon juice won’t give you the same pop of flavor. The zest especially adds so much to both the batter and the glaze.
2. Fresh or frozen blueberries both work.
   If you’re using frozen, don’t thaw them, just toss in a little flour before folding them into the batter. This helps prevent them from sinking and keeps the batter from turning purple. I do prefer the juicy pop of fresh blueberries though!
3. All-purpose or whole wheat?
   If you like a more traditional bakery-style coffee cake, stick with all-purpose flour. If you want a slightly heartier texture with a hint of nuttiness, a 50/50 blend of freshly ground wheat and all-purpose flour is amazing. Increase the moisture slightly and let the batter rest before baking.
4. Let the cake cool slightly before glazing.
   This keeps the glaze from melting right into the crumb topping and helps it set beautifully across the top.

How to Store & Reheat

You can leave the Lemon-Blueberry Coffee Cake covered at room temperature for up to 2 days, or refrigerate it for up to 5. I usually slice what we don’t eat right away and store it in an airtight container in the fridge. You can also freeze individual slices, just wrap tightly and thaw overnight or warm them in the toaster oven for a few minutes.

Can I Make This Lemon-Blueberry Coffee Cake Ahead of Time?

Absolutely. This cake is ideal for baking ahead. You can prep the whole thing the night before and bake it in the morning, or bake it the day before and simply reheat it. If you’re bringing it to a gathering, wait to add the glaze until just before serving so it looks fresh and glossy.

This Recipe in our kitchen!

I started making this coffee cake on Saturday mornings when we wanted something a little more special than cereal or scrambled eggs. And the first time I pulled it from the oven, it became an instant favorite with the kids. The texture is soft but not flimsy, the blueberries burst just enough to leave little pockets of sweetness, and that crumb topping… well, you’ll see.

Now it’s one of those recipes I make when I want to bring something comforting to a friend, when I know the kids have a busy morning and need something they’ll actually eat, or when I just want the house to smell amazing.

There’s something about the lemon and blueberry combo it just feels fresh and familiar all at once. It reminds me of springtime, Early summer, breakfast around the table with sleepy kids and hot coffee, and of how the best recipes are the ones that bring people together without making you spend all day in the kitchen.

My favorite tweaks?

Here are a few ways to tweak the base recipe without losing what makes it special:
    •    Add a cream cheese swirl to the batter before baking for extra richness
    •    Swap blueberries for blackberries or raspberries for a fun twist
    •    Stir chopped toasted almonds or walnuts into the crumb topping for texture
    •    Make it gluten-free with a 1:1 baking flour blend
