This Blueberry Poppyseed Loaf Cake is the sister (or cousin) to a classic lemon poppyseed cake. Lemon poppyseed cakes are so common and it screams springtime. But what loafcakes can we enjoy in the fall with fruity flavors? Blueberries are popular in the spring + summer, but they are rich in flavor that they carry over into the fall + winter. This loaf cake will have you enjoying every bite,

On top of these robust flavors, we’ve combined sour cream + buttermilk into one loaf. On their own buttermilk + sour cream bring flavor and smooth textures to cakes. It’s moist, and heavy yet soft to the bite. For this recipe, if you don’t have sour cream, make it 1/2 a cup of buttermilk, and if you don’t have buttermilk then make it 1/2 cup of sour cream. Both of these ingredients combined elevate the rich flavors + brings out the moist thick layers of the loaf cake. Just take a look at the thick slices in the photos!

Loaf Cakes

Loaf cakes are easy to package, serve, require little to no icing, and can be done in about 2 hours. This seems like a long time, but the majority of this time is baking + cooling. The actual work is mixing and pouring a glaze. I use 9×13 loaf pans. Line your pans with parchment paper to easily pull out your loaf cakes. Although loaf cakes take a long time to bake, make sure you take it out exactly at the time it’s ready!

Bring these cakes to parties, take them on picnics, or add it to your lunch for a sneaky dessert! It requires no fork, no smushed icing, but still has all of the delightful flavors of a traditional cake.

Blueberry Almond Glaze

  • In a small pan over medium heat, pour in blueberries + sugar. Cook until blueberries start to soften (3-5 minutes). 
  • With a sieve, pour blueberry mix over a small bowl + pour the cranberry mixture into the sieve. Let cool for 10 minutes. 
  • Stir in powdered sugar + almond extract until completely dissolve. The glaze will be thick.

*Coating your blueberries in flour prevents too much leakage and your blueberries sinking to the bottom of the loaf.
