What Ingredients You Will Need

This tender lemon blueberry coffee cake keeps things straightforward, relying on simple, wholesome ingredients that come together beautifully. Most of these you probably have on hand, except maybe fresh blueberries, which are totally worth grabbing when in season!

• For the Cake:
  • All-purpose flour – 2 cups (240g), sifted for a light texture
  • Baking powder – 2 teaspoons (8g), to help it rise just right
  • Salt – ½ teaspoon (3g), to balance the sweetness
  • Unsalted butter – ½ cup (113g), softened (I prefer Land O’ Lakes for creaminess)
  • Granulated sugar – ¾ cup (150g), for sweetness without overpowering
  • Large eggs – 2, room temperature
  • Whole milk – ½ cup (120ml), adds moisture and richness
  • Fresh lemon zest – 2 tablespoons (from about 2 medium lemons), finely grated for maximum zing
  • Pure vanilla extract – 1 teaspoon (5ml), enhances flavor depth
  • Fresh blueberries – 1 ½ cups (225g), washed and patted dry (frozen works too, just don’t thaw)
• For the Crunchy Crumb Topping:
  • All-purpose flour – ½ cup (60g)
  • Granulated sugar – ⅓ cup (65g)
  • Brown sugar – ⅓ cup packed (70g), adds that caramel note
  • Unsalted butter – ¼ cup (57g), cold and cubed for perfect crumbly texture
  • Ground cinnamon – ½ teaspoon (1g), optional but highly recommended
  • Pinch of salt, to balance sweetness

Substitution tips: For a gluten-free version, swap the all-purpose flour with a 1:1 gluten-free baking flour. You can replace whole milk with almond or oat milk for a dairy-free option, and use coconut oil instead of butter in the crumb topping if you like. When fresh blueberries aren’t available, frozen berries are the next best thing—just toss them in frozen to avoid too much color bleed.

Equipment Needed

Making this lemon blueberry coffee cake doesn’t demand fancy gadgets. Here’s what you’ll want on hand:

• 8-inch (20 cm) square or round baking pan – a classic size that bakes evenly
• Mixing bowls – one large for batter, one small for crumb topping
• Electric mixer or sturdy whisk – I usually grab my handheld mixer for speed, but a whisk works fine if you’re up for a little arm work
• Zester or fine grater – essential for getting that bright lemon zest (a microplane works wonders here)
• Measuring cups and spoons – precise measurements make a difference in baking
• Rubber spatula – for folding in blueberries gently without breaking them
• Cooling rack – to let the cake cool evenly

If you don’t have a zester, a sharp paring knife to carefully peel thin strips of lemon peel works too, just avoid the bitter white pith. For the pan, if you only have a loaf pan, that’s fine—just adjust baking time slightly and keep an eye on it. I once baked this in a cast iron skillet, which gave it a lovely crisp edge that was a happy accident!

Preparation Method

1. Preheat your oven to 350°F (175°C) and grease your baking pan with butter or nonstick spray. Line the bottom with parchment paper for easy removal.
2. Mix the dry ingredients: In a medium bowl, whisk together 2 cups (240g) flour, baking powder, and salt. Set aside.
3. Cream the butter and sugar: In a large bowl, beat the softened butter (½ cup/113g) with granulated sugar (¾ cup/150g) until pale and fluffy—about 3-4 minutes. This step is key for a tender crumb.
4. Add eggs and flavorings: Beat in the eggs one at a time, then stir in the lemon zest and vanilla extract (1 teaspoon/5ml). The batter will smell wonderfully fresh and bright here.
5. Combine wet and dry: Alternately add the dry flour mixture and milk (½ cup/120ml) to the butter mixture, starting and ending with the dry ingredients. Mix gently after each addition until just combined—don’t overmix or the cake will get tough.
6. Fold in the blueberries: Gently fold in 1 ½ cups (225g) fresh blueberries with a rubber spatula, careful not to break them up too much. This keeps bursts of juicy blueberry in the cake.
7. Prepare the crumb topping: In a small bowl, mix ½ cup (60g) flour, granulated sugar (⅓ cup/65g), brown sugar (⅓ cup/70g), cinnamon (½ teaspoon/1g), and a pinch of salt. Cut in cold cubed butter (¼ cup/57g) using a pastry cutter or your fingertips until the mixture resembles coarse crumbs.
8. Assemble and bake: Pour the batter into your prepared pan and spread evenly. Sprinkle the crumb topping generously over the surface. Pop it into the preheated oven and bake for 40-45 minutes or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
9. Cool and serve: Let the cake cool in the pan for about 15 minutes, then transfer to a cooling rack. This waiting game is tough, but it helps the cake set and the flavors meld.

Pro tip: If your crumb topping starts to brown too fast, tent the cake loosely with foil halfway through baking. Also, remember that ovens can vary, so start checking at 35 minutes if yours tends to run hot. The cake should be golden on top and springy but not wet in the center.

Cooking Tips & Techniques

Here’s what I’ve learned from making this tender lemon blueberry coffee cake more times than I can count (and yes, with a few flops along the way):

• Don’t overmix the batter. Once you add the flour, mix just until combined. Overmixing develops gluten, leading to a dense, tough cake instead of a tender one.
• Use fresh lemon zest. Pre-grated lemon zest from the store just doesn’t have the same zing or freshness. I keep a microplane handy and zest directly into the batter to catch all that fragrant oil.
• Keep the blueberries dry. Wash and thoroughly dry your blueberries before folding them in. Wet berries can cause the batter to get watery and the crumb to sink.
• Chill the butter for the topping. Cold butter cut into the sugar and flour creates that perfect crumbly texture. If the butter gets too soft, the topping won’t crisp up right.
• Timing matters. Try to get the cake into the oven soon after mixing to avoid the blueberries bleeding color and the batter settling.
• Multitask wisely. While the cake bakes, clean your bowls and prep your coffee—you’ll thank yourself later for the smooth morning flow.

One time, I forgot to set the timer and ended up with a slightly darker topping, which actually tasted like caramelized heaven. So, sometimes a little imperfection adds character!

Variations & Adaptations

This lemon blueberry coffee cake is versatile and easy to tweak depending on what you have or your taste preferences:

• Seasonal fruit swap: In fall, try diced apples with a sprinkle of nutmeg instead of blueberries. Summer? Fresh raspberries or blackberries work beautifully.
• Gluten-free option: Use a gluten-free baking blend instead of all-purpose flour. Make sure your baking powder is gluten-free too.
• Dairy-free version: Swap butter with coconut oil or vegan butter, and use almond or oat milk instead of dairy.
• Extra citrus kick: Add a tablespoon of fresh lemon juice to the batter for tangier flavor, or a light lemon glaze drizzle after baking.
• Nutty crumb topping: Toss in ¼ cup chopped pecans or walnuts for extra crunch and flavor.

I once tried swapping out lemon zest for orange zest—delicious, but not quite the same brightness. Still, it was a fun twist when I ran out of lemons!

Serving & Storage Suggestions

This coffee cake is best served slightly warm or at room temperature, letting that crumb topping stay perfectly crisp. I like slicing it into generous squares and pairing it with a cup of freshly brewed coffee or a creamy latte.

For a little extra indulgence, a dollop of whipped cream or a smear of cream cheese frosting complements the lemon and blueberry flavors beautifully without overpowering them.

To store, cover the cake tightly with plastic wrap or keep it in an airtight container at room temperature for up to 2 days. For longer storage, wrap it well and freeze for up to 3 months. Thaw overnight in the fridge and warm gently in the oven to refresh that crumbly topping.

Fun fact: The flavors mellow and meld even more after a day, so if you can wait, the next day’s slice is sometimes even better!

FAQs

Can I use frozen blueberries in this coffee cake?

Yes! Use frozen blueberries straight from the freezer and fold them gently into the batter to avoid too much color bleed. Don’t thaw them first.

How do I keep the crumb topping crunchy after baking?

Make sure the butter in the topping is cold when mixing, and avoid covering the cake tightly while it’s warm. Store uncovered at room temperature or loosely tented with foil.

Can I make this cake ahead of time?

Absolutely. It tastes great the next day, and flavors develop even more. Store it covered at room temperature or refrigerate and warm gently before serving.

Is this recipe suitable for gluten-free diets?

It can be adapted by using a 1:1 gluten-free baking flour blend and ensuring all other ingredients are gluten-free.

What’s the best way to zest a lemon for this recipe?

Use a microplane zester to grate just the yellow outer layer without the bitter white pith. If you don’t have a zester, a vegetable peeler works—just finely mince the peel.
