When the mixture is fluffy, add in the eggs one at a time, then stir in the buttermilk and vanilla extract. It’s at this point that I can almost taste the deliciousness coming together! In a separate bowl, mix the flour, baking powder, baking soda, and salt. Gradually add the dry mixture to the wet ingredients, mixing until just combined. Lastly, fold in both the pureed and whole blackberries—this not only adds flavor but also creates beautiful swirls of purple throughout the batter.
Divide the batter evenly between the two prepared pans and bake for about 25-30 minutes, or until a toothpick inserted in the center comes out clean. While the cakes are baking, my kitchen fills with the divine aroma of baking bread! Once they’re done, let them cool in the pans for about 10 minutes before transferring them to a cooling rack to cool completely. While they cool, I often start on my scrumptious cream cheese frosting, where I beat together the softened cream cheese, powdered sugar, and lemon juice until smooth and creamy.
Pro Tips for Best Results
When I first made this cake, I realized that the quality of the blackberries greatly impacts the flavor. I always opt for fresh, ripe berries, and if I’m in a pinch, frozen ones work too, but be cautious of excess moisture! I’ve tested this three ways—using just pureed berries or just whole berries, but finding a balance is what makes this cake so delightful.
Another tip is to let your cakes cool completely before frosting; it makes such a difference in achieving a smooth finish with the cream cheese frosting. Otherwise, I’ve had situations where the frosting just melts into a gooey mess. I also recommend placing the frosted cake in the fridge for a bit, as this helps set the frosting and makes slicing easier later on.
Lastly, I can’t stress enough how important it is to measure your ingredients accurately, especially the flour. I’ve made the mistake of packing my flour too tightly, which led to a dry cake. Now, I spoon the flour into my measuring cup and level it off, and it’s been a game changer!
Common Mistakes to Avoid
One of the biggest mistakes I made when first attempting this cake was not properly mixing the ingredients. I was so eager to finish that I didn’t take the time to fully blend the butter and sugar, which left my cake dense instead of light and fluffy. Make sure to mix until the butter-sugar mixture is pale and airy. (See the next page below to continue…)
