Blueberry Pistachio Layer Cake

The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions, to ensure that you have all the ingredients and equipment required and understand the steps and timings involved.

Summertime is the perfect time for get-togethers with family and friends and this pretty blueberry pistachio layer cake is perfect for any summer party!

You’ll start by transforming a box of vanilla cake mix into a moist and flavorful cake by using butter, milk, and eggs (instead of the usual oil, water, and eggs).

Then, the layers are sandwiched with light and fluffy buttercream frosting made with blueberry preserves for added sweetness.

With the same blueberry frosting covering the whole cake, it is finished off with chopped pistachios and swirls of buttercream. You could add some fresh blueberries on top too if you like.

Don’t let the thought of making a layer cake scare you, they are not as hard as you may think!

And besides, what matters the most is the taste, and your guests (and you) will love this delicious cake!

A Recipe for Blueberry Pistachio Layer Cake

Ingredients & Equipment Used In This Recipe

While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients and equipment needed for this recipe have been linked to Amazon or other stores if available online. Staple ingredients such as oil, salt, sugar, etc., aren’t always included here as you’re likely to have those in your kitchen. The complete list of ALL ingredients with measurements is found on the recipe card.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. Please note, you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).

Recipe Tips

  • Place a blob of frosting in the center of the cake board to hold the first layer of cake in place.
  • After layering the cake with frosting, add a thin layer of frosting around the top and sides of the cake. This is called a crumb coat. Place the cake in the fridge for about an hour to firm up a little before completely frosting the cake.
  • Use a cake turntable and scraper for professional-looking frosting results. Take your time to slather on the frosting, and use the scraper (or spatula/palette knife) to smooth it out, removing any excess back to the bowl. It doesn’t have to be perfect!
  • If you are worried about piping swirls on top of the cake, practice on a piece of parchment paper first, and scoop the frosting back into the bag!
