• Fast prep: mix everything by hand in one bowl—no fancy stand mixer needed because melted butter does the job.
• Delicious texture: quick oats and Greek yogurt combine for a hearty yet soft crumb that feels like a perfect cross between cake and muffin.

This breakfast cake is all about big flavor with minimal work: about 15 minutes of mixing in just one bowl, then an hour in the oven. Here’s why you’ll want to make it again and again.

Ingredients You’ll Need

• flour
• quick oats
• baking powder
• baking soda
• salt
• 1/2 cup sugar
• zest of 2 lemons, grated finely (rubbed into the sugar)
• Greek yogurt
• melted butter
• an egg
• 1 tablespoon fresh lemon juice (about half a lemon)
• fresh or frozen blueberries
• 1 tablespoon sugar (for sprinkling on top)

Step-by-Step Method

1. Gather and measure all ingredients and have them ready to go.
2. Preheat oven to 350°F (175°C) and grease and flour an 8.5-inch springform pan.
3. In a medium bowl, whisk together the flour, quick oats, baking powder, baking soda, and salt.

4. Place ½ cup sugar in a separate bowl; grate the zest of 2 lemons finely and rub the zest into the sugar.

   
5. Let melted butter cool slightly before combining with cold ingredients.
6. To the lemony sugar, stir in Greek yogurt, cooled melted butter, and 1 egg; add 1 tablespoon fresh lemon juice and whisk until smooth.
7. Add the flour-and-oats mixture to the wet ingredients and gently fold until no flour streaks remain.

8. If using frozen blueberries, toss them lightly in 1 teaspoon flour (do not thaw) to help prevent sinking.

   

9. Spoon half the batter into the prepared pan, spread it evenly, and sprinkle half the blueberries over the top.
10. Dollop the remaining batter over the blueberries, gently spread to cover, scatter the remaining blueberries on top, press them down gently to nestle, and sprinkle the last tablespoon of sugar over the surface.
11. Bake in the preheated oven 40–50 minutes for fresh blueberries or 50–60 minutes for frozen berries, until the top is golden and a skewer inserted in the center comes out with a few moist crumbs (not wet batter).

12. Let the cake cool in the pan for about 10 minutes, then carefully remove it from the springform pan.

    

Smart Baking Tips

• Rub that lemon zest right into the sugar as directed—this step really pulls out those lemon oils to punch up the flavor.
• Allow your melted butter to cool a bit before mixing it with the yogurt and egg to avoid accidentally cooking the egg.
• When combining dry into wet ingredients, fold gently and just until no flour streaks remain to keep the crumb light and airy.
• If you’re using frozen blueberries, skip thawing—fold them in frozen and plan for an extra 10-15 minutes of bake time. For a visual guide to folding in frozen berries without streaking, see these step-by-step lemon blueberry scones.
• To keep berries from sinking or turning your batter purple, toss them lightly in a teaspoon of flour before folding.
• Make sure to grease and flour your pan well, and after baking let the cake rest in the pan for 10 minutes before removing so it holds together beautifully.
• Always check doneness by inserting a skewer—you’re aiming for a few moist crumbs on the skewer, not wet batter.

Flavor Swaps and Add-Ins

• Berry switch-up: swap in raspberries, chopped strawberries, or a mix of berries. If you love the strawberry-lemon pairing, try this Strawberry Lemon Cake recipe. Just keep an eye on baking time if your fruit is extra juicy.
• Different citrus vibes: try orange zest and a tablespoon of orange juice instead of lemon for a softer, sweeter twist.
• Yogurt swap: if you don’t have Greek yogurt, full-fat sour cream or regular plain yogurt will work great too, keeping the texture tender.
• Butter alternative: swap melted butter for a neutral oil like canola or vegetable oil for a dairy-free option. Your crumb will be slightly softer but still delicious.
• Toppings to try: mix up a simple streusel with butter, flour, sugar, and oats to sprinkle on top before baking, or drizzle a lemon glaze once the cake cools down.
• Turn it into muffins: scoop batter into muffin tins, filling about two-thirds full, and bake for 18-22 minutes for quick, grab-and-go treats. For more muffin pointers, see the Lemon Poppy Seed Muffins recipe.

Storage and Make-Ahead Tips

If you have leftovers, keep them covered at room temperature for a few days—that’s perfect for a quick breakfast snack. For longer freshness, store in an airtight container in the fridge for up to 3-4 days. To freeze, wrap the fully cooled cake or individual slices tightly in plastic wrap, then pop them in a freezer bag. They’ll keep well for 2-3 months. If you’re stocking the freezer for later, lemon bars with a shortbread crust also freeze well. When ready, thaw slices at room temp and warm them up quickly.

To reheat, zap a single slice in the microwave for 15-30 seconds until warm, or place it in a 300°F oven for about 8-12 minutes (add a few more minutes if frozen) to bring back that lightly crisp sugared top.

Answers to Common Questions

• Can I use frozen blueberries? — Absolutely! Just keep them frozen when folding into the batter. The bake time will be a bit longer, about 50-60 minutes instead of 40-50.
• Can I bake this in a different pan? — Yes, you can use a 9-inch round pan or even a loaf pan. Just watch the bake time carefully: a 9-inch round might finish faster (start checking at around 35 minutes), while a loaf pan might need extra time.
• Do I have to use quick-cooking oats? Can I use instant? — Quick oats work best here because they add to the texture without breaking down too much. Instant oats break down more, which can change the crumb. Old-fashioned rolled oats would also work but will give you a chewier texture. For a quick comparison of how oat types affect chew, see our Easy Oatmeal Chocolate Chip Cookies recipe.
• Can I substitute Greek yogurt? — For sure! Full-fat sour cream or plain yogurt are great swaps—they keep the batter moist and tender.
• Why rub lemon zest into the sugar? — Rubbing zest into sugar releases the oils and spreads the lemon flavor evenly throughout the cake, making every bite lively and fresh. You can see this technique in action in our Lemon Blueberry Layer Cake.
• How do I know when it’s done baking? — The top should be golden, and a skewer poked into the center should come out with a few moist crumbs, not wet batter.
