This Lemon Poppy Seed Bundt Cake is pure sunshine in dessert form. Each slice is moist and bursting with bright citrus from fresh lemon zest, dotted with poppy seeds for a slight crunch, and topped with a glossy lemony glaze. Whether you are baking for a holiday, a brunch, or just to brighten up an ordinary afternoon, this cake brings a perfect balance of sweet and tangy flavors that everyone loves.
I first baked this for my mother’s birthday and she absolutely raved about how it tasted like a sunny day. It has since become a tradition for spring gatherings in my family.
Ingredients
- All purpose flour: helps give the cake structure for a perfect bundt that holds its beautiful shape. Choose a good quality flour that is not self rising.
- Baking powder: ensures a gentle lift for a light and fluffy crumb. Fresh baking powder makes a difference so check the date.
- Salt: balances sweetness and sharpens the lemony notes. Fine sea salt distributes well but any salt will work in a pinch.
- Poppy seeds: add subtle crunch and visual flair. Look for fresh poppy seeds with a slight sheen to ensure they are not stale.
- Granulated sugar: sweetens and gives tender texture. Pure cane sugar gives a clean flavor.
- Lemon zest: infuses the cake with real citrus punch. Choose firm heavy lemons and zest only the yellow part for best taste.
- Butter: unsalted and at room temp for maximum creaminess. European or high fat butter gives best results if available.
- Buttermilk: adds tang and moisture. If you do not have it combine milk with a splash of lemon juice and let sit a few minutes.
- Eggs: bind everything and create richness. Use large eggs at room temperature for easy mixing.
- Powdered sugar: forms the glaze. Sift if lumpy for a smooth finish.
- Vanilla extract: gives the glaze an extra layer of flavor. Pure vanilla is worth it.
- Lemon juice: freshly squeezed for zing in the glaze. Use the lemons you’ve zested for the freshest juice.
- Milk: thins the glaze as needed. Whole milk gives a lusher finish but any milk type works.
Step-by-Step Instructions
- Prepare the Pan and Oven:
- Preheat your oven to three hundred fifty degrees Fahrenheit. Grease your bundt pan very thoroughly with cooking spray or soft butter making sure to get into every curve and detail so the cake releases without sticking.
- Mix the Dry Ingredients:
- In a large bowl stir flour with baking powder salt and poppy seeds until evenly combined and set aside. This prevents clumps and ensures the poppy seeds are evenly distributed.
- Infuse the Sugar with Lemon:
- In your stand mixer bowl combine granulated sugar and lemon zest. Rub them together with your fingers or use the whisk attachment for about two minutes until the sugar smells strongly of lemon and looks slightly damp.
- Cream Butter into Lemon Sugar:
- Add room temperature butter to the lemon sugar and beat on medium speed for around four minutes until the mixture is pale and fluffy. Stop and scrape the bowl often so all the butter is incorporated.
- Add Wet Ingredients:
- Beat in eggs one at a time allowing each to fully blend. Add buttermilk and mix until the batter is smooth and glossy about two to three minutes.
- Combine Wet and Dry Mixtures:
- Add half the dry mixture and gently mix until just incorporated. Add the remaining flour blend on low until you see no more dry spots. Over mixing at this stage can make your cake tough so stop as soon as it all comes together.
- Pour and Bake:
- Spoon the batter into your prepared pan and smooth the top. Gently tap the pan on the counter to remove air bubbles. Bake for fifty five to sixty five minutes or until a toothpick comes out clean from the center of the cake.
- Make the Lemon Glaze:
- While the cake bakes whisk powdered sugar with lemon juice vanilla and enough milk to form a runny glaze. Aim for a consistency that drizzles but does not run straight off the spoon.
- Cool and Remove the Cake:
- Once baked let the cake rest in its pan for ten minutes to loosen. Slide a butter knife gently around the edges to help release. Invert onto your serving plate and let it finish cooling for another ten to twenty minutes.
- Glaze and Serve:
- Drizzle the slightly warm or fully cooled cake with lemon glaze so it trickles down the sides. Let it set a few minutes before slicing to enjoy.

I always look forward to zesting the lemons for this recipe. The fragrance fills my whole kitchen and instantly puts me in a good mood. My niece loves helping with the glaze and always insists on adding a little extra drizzle.
Storage Tips
Store leftover cake tightly wrapped at room temperature for up to three days. The glaze helps seal in moisture. If you plan to keep it longer refrigerate slices in an airtight container where they stay fresh for up to a week. Bring to room temperature before serving for the softest texture. You can also freeze slices for up to three months. Wrap well and let thaw uncovered so the glaze does not get sticky.
Ingredient Substitutions
If you do not have buttermilk you can make your own by stirring a tablespoon of lemon juice into a cup of regular milk and letting it rest for five minutes. Plain Greek yogurt thinned with a splash of water is another great stand in. Orange zest works if you want a different citrus profile. Vegan butter and flax eggs can substitute for a dairy free version.

Serving Suggestions
This cake is gorgeous for brunch birthdays showers or tea parties. Try adding thin lemon slices or edible flowers for a pretty finish. Serve with fresh raspberries or blueberries for an extra burst of color and tartness. Whipped cream pairs well or keep it simple with just the glaze.

Bringing this cake to a gathering always sparks conversation and nostalgia.
Frequently Asked Questions
- → What can I use instead of buttermilk?
If you don't have buttermilk, mix 1 cup of milk with 1 tablespoon of lemon juice or vinegar and let it sit for a few minutes before using. This creates a tang similar to traditional buttermilk.
- → How do I prevent the cake from sticking to the pan?
Thoroughly grease the bundt pan with butter or nonstick spray, making sure to get into all the grooves. Use a pastry brush for thorough coverage and let the cake cool before unmolding.
- → Can I freeze this cake?
Yes, bake and cool the cake fully. Wrap slices or the whole cake tightly in plastic wrap, then foil, and freeze for up to three months. Thaw at room temperature before serving.
- → Why is my glaze translucent?
Fresh lemon juice and milk create a runny glaze that looks translucent at first. As it dries and soaks into the cake, it becomes opaque and beautifully glossy.
- → How do I achieve the perfect crumb?
Mix your batter just until the ingredients combine to avoid overmixing, which can make the cake dense. Use room temperature butter for even blending and a tender texture.
