High-Protein Lemon Poppy Seed Bundt Cake

Description

Bright, lemony, moist, and lightly sweet, this High-Protein Lemon Poppy Seed Bundt Cake gives you classic bakery-style flavor with a protein-friendly twist. Greek yogurt and vanilla protein powder help create a soft, tender crumb, while fresh lemon zest and poppy seeds add plenty of fresh flavor. It’s a delicious option when you want a lighter dessert without giving up that irresistible lemon cake texture.

Can This Lemon Poppy Seed Bundt Cake Support Weight Loss Goals?

This cake can fit into a balanced weight-conscious eating pattern because it provides protein and satisfying texture while using less added sugar than a traditional bundt cake. Greek yogurt, eggs, egg whites, and protein powder increase the protein content, which can make a dessert more filling. Portion size and your overall daily nutrition still matter.

Does Lemon Poppy Seed Bundt Cake Fit a High-Protein Lifestyle?

Yes! Each serving provides approximately 11–13g of protein, making it more protein-rich than a traditional lemon cake. It contains moderate carbohydrates and can work well as a balanced snack or dessert. The fresh lemon flavor keeps it tasting light and refreshing rather than overly rich. For a lower-carb variation, use a suitable low-carb flour blend.

Using too much protein powder: Excess protein powder can make the cake dry and dense, so measure carefully.
Skipping the lemon zest: Juice alone won’t provide the same intense lemon aroma.
Removing the cake too early: Let it cool properly before turning it out of the bundt pan.

Ingredients

For the Cake

1½ cups all-purpose flour
¾ cup vanilla protein powder
1½ teaspoons baking powder
½ teaspoon baking soda
¼ teaspoon salt
2 tablespoons poppy seeds
2 large eggs
½ cup liquid egg whites
1 cup plain nonfat or low-fat Greek yogurt
⅓ cup granulated monk-fruit sweetener or preferred sweetener
¼ cup light olive oil or avocado oil
2 tablespoons fresh lemon juice
1 tablespoon finely grated lemon zest
⅓ cup unsweetened almond milk
1 teaspoon vanilla extract

For the Lemon Glaze

½ cup powdered monk-fruit sweetener
1–2 tablespoons fresh lemon juice
1 tablespoon Greek yogurt, optional, for a creamier glaze
Directions
Preheat the oven to 350°F (175°C). Thoroughly grease a 10–12 cup bundt pan, making sure to coat all the grooves.
Mix the dry ingredients. In a large bowl, whisk together flour, protein powder, baking powder, baking soda, salt, and poppy seeds.
Prepare the wet mixture. In another bowl, whisk eggs, egg whites, Greek yogurt, sweetener, oil, lemon juice, lemon zest, almond milk, and vanilla until smooth.
Combine gently. Slowly add the dry ingredients to the wet mixture. Fold until just combined. Do not overmix, as this can make a protein cake dense.
Check the batter texture. It should be thick but pourable. If it feels unusually thick because of your protein powder, add 1 tablespoon almond milk at a time until the batter reaches the correct consistency.
Fill the bundt pan. Pour the batter evenly into the prepared pan and gently tap the pan on the counter once or twice to remove large air pockets.
Bake for 35–45 minutes, or until the top is lightly golden and a toothpick inserted into the thickest part comes out mostly clean with a few moist crumbs.
Cool properly. Let the cake rest in the pan for about 15 minutes, then carefully invert it onto a cooling rack. Allow it to cool completely before glazing.
Make the glaze. Whisk powdered sweetener with lemon juice until smooth. Add Greek yogurt if you want a slightly creamier glaze.
Finish the cake. Drizzle the lemon glaze over the cooled bundt cake, then sprinkle a few extra poppy seeds and lemon zest over the top if desired.
High-Protein Tips
Use a whey/casein blend or a protein powder that performs well in baking for a softer crumb.
Don’t replace all the flour with protein powder; too much can make the cake rubbery.
Greek yogurt adds moisture while increasing protein.
Allow the cake to cool fully before slicing for the cleanest pieces.
