Lemon-Blueberry Bundt® Cake

Preheat the oven to 350 degrees F (175 degrees C).

Grease and flour a fluted tube pan (such as Bundt®).

Pat blueberries dry and place into a plastic bag.

Toss with 1 1/2 teaspoons flour until all berries are dusted.

Combine 2 1/2 cups flour, almond flour, baking powder, and salt in a medium bowl; stir with a fork until well blended.

Combine sugar and butter in the bowl of a stand mixer.

Cream together on high speed until light and fluffy, about 4 minutes.

Reduce speed to low; add eggs, 1 at a time, beating after each addition and scraping the bowl as needed.

Mix in about 1/3 of the flour mixture, followed by 1/2 of the buttermilk, beating after each addition.

Repeat, ending with the final 1/3 of the flour mixture.

Add lemon curd, lemon zest, and vanilla extract; beat until just combined.

Turn off the mixer and fold in blueberries.

Pour batter into the prepared pan, cleaning the mixer bowl and beater with a scraper.

Tap the tube pan lightly to remove any pockets of air.

Bake in the preheated oven until a toothpick inserted into the center of the cake comes out clean, 55 to 65 minutes.

Allow the cake to cool completely in the pan on a wire rack, about 30 minutes.

Turn out onto a decorative plate.

Stir powdered sugar, lemon juice, lemon zest, and salt together in a microwave-safe glass bowl for the glaze.

Place butter on top of the glaze and microwave until the mixture bubbles and the butter is melted, about 1 minute.

Whisk until smooth.

Allow glaze to cool for about 15 minutes; pour over cake.

Garnish with blueberries, if desired.
