How to Make Lemon Poppy Seed Cornmeal Cake

Step 1: Preheat

Preheat your oven to 325°F. Grease and flour a 6-cup fluted cake pan (or small Bundt pan).

Step 2: Cream Butter and Sugar

In a large bowl, beat the softened butter and sugar until light and fluffy (about 3–4 minutes).

Step 3: Add Eggs and Flavor

Add eggs one at a time, beating well after each addition. Mix in lemon zest, lemon juice, and vanilla extract.

Step 4: Mix Dry Ingredients

In a separate bowl, whisk together:

• Flour
• Cornmeal
• Poppy seeds
• Baking powder
• Salt

Step 5: Combine Wet and Dry

With mixer on low speed, gradually add the dry ingredients to the butter mixture, alternating with the buttermilk. Start and end with the flour mixture. Mix just until combined — do not overmix.

Step 6: Bake

Pour batter into prepared pan. Gently tap the pan on the counter to release air bubbles.

Bake for about 45 minutes, or until a toothpick inserted in the center comes out clean.

Let cool in the pan for 10 minutes, then invert onto a wire rack and cool completely.

Make the Lemon Glaze

In a small bowl, whisk powdered sugar and lemon juice until smooth.
Spoon over the cooled cake, letting it drip down the sides.

Allow glaze to set before slicing.

Tips for the Best Lemon Cornmeal Cake

• Use fresh lemon juice and zest for the brightest flavor.
• Make sure your butter is truly softened for a fluffy texture.
• Finely ground cornmeal works best — coarse cornmeal can make the cake gritty.
• Don’t overmix after adding flour. This keeps the cake tender.

Storage

• Store covered at room temperature for up to 3 days.
• Refrigerate for up to 5 days.
• Freeze (without glaze) for up to 2 months.
