Instructions
- Prepare Your Workspace:
- Begin by organizing all ingredients measured and at room temperature especially the butter and eggs which incorporate much better when not cold. Preheat your oven to exactly 350°F using an oven thermometer for accuracy. Prepare your cake pans meticulously by greasing thoroughly then adding parchment circles to ensure perfect release.
- Mix Dry Ingredients:
- Whisk the flour baking powder baking soda and salt together with a light hand until completely combined about 30 seconds. This even distribution prevents pockets of leavening agents that could create uneven rising. The mixture should look uniform in color with no visible streaks.
- Cream Butter and Sugar:
- Beat butter and sugar together on medium high speed for a full 3 to 4 minutes until the mixture becomes noticeably lighter in both color and texture. This incorporates air that creates the cake's structure. You'll know it's ready when it's fluffy enough that the sugar granules are less noticeable.
- Add Eggs and Vanilla:
- Add each egg individually beating for 30 seconds between additions to properly emulsify. Scrape down the bowl thoroughly after each addition to ensure even mixing. When you add the vanilla extract mix just until incorporated about 10 seconds to preserve the flavor compounds.
- Combine Wet and Dry Ingredients:
- Starting and ending with the flour mixture add ingredients in this order flour milk flour milk flour. Mix on low speed just until combined after each addition about 5 to 10 seconds. Overmixing at this stage develops gluten and makes the cake tough so stop as soon as the flour disappears.
- Bake to Perfection:
- Divide batter evenly using a kitchen scale for precision about 450g per pan. Smooth tops with an offset spatula and tap pans gently on counter to release air bubbles. Bake in the center rack rotating pans halfway through baking. Test doneness at 25 minutes by inserting a toothpick in the center it should come out with a few moist crumbs but no wet batter.
- Create Pickle Buttercream:
- Beat butter on medium high speed until extremely light and fluffy about 3 minutes. Add powdered sugar one cup at a time mixing on low until incorporated then increasing speed to medium to integrate fully. Add pickle juice one tablespoon at a time tasting between additions to achieve your desired level of tanginess. Mix in minced pickles lemon zest and salt until just distributed. If needed add milk by the teaspoon until the frosting reaches a smooth spreadable consistency.
- Assemble Your Masterpiece:
- Place first cake layer on a cardboard round or serving plate. Apply a generous cup of buttercream spreading to an even layer using an offset spatula. Top with second cake layer pressing gently to secure and repeat frosting process. Add final layer and apply a thin crumb coat of frosting to the entire cake. Refrigerate for 15 minutes to set then apply final coat of frosting decorating as desired with additional pickles or sprinkles.
Save The pickle juice is truly the star ingredient in this recipe. I discovered its potential while making a traditional cake and accidentally spilled some pickle brine into my buttercream. Instead of starting over, I decided to taste it and was blown away by how the tangy notes actually enhanced the sweetness. Now I keep premium dill pickles on hand specifically for baking this cake.
Storage Tips
This cake maintains its moisture beautifully when stored properly. Keep leftovers in an airtight container at room temperature for up to 2 days or refrigerated for up to 5 days. Allow refrigerated cake to come to room temperature for about 30 minutes before serving for the best flavor and texture. The cold tends to dull the pickle flavor and firm the buttercream too much.
If you need to make this cake in advance, you can freeze unfrosted cake layers wrapped individually in plastic wrap and then aluminum foil for up to 3 months. The buttercream can also be frozen separately in an airtight container for up to 1 month. Thaw both completely before assembling.
Ingredient Substitutions
For a dairy free version, substitute plant based butter in equal amounts for both the cake and frosting. Oat milk works particularly well as a substitute for whole milk as it has a similar fat content. The texture may be slightly different but still delicious.
If you prefer a less intense pickle flavor, bread and butter pickle juice offers a milder, sweeter tang that some find more approachable. You can also replace half the pickle juice with lemon juice for a different type of tartness.
For those avoiding artificial colors, the green food coloring can be replaced with spirulina powder or matcha tea powder for a natural green hue, though the color will be more subtle and earthy.
Serving Suggestions
This unique cake deserves a special presentation. Serve slices alongside small glasses of milk infused with vanilla bean to cleanse the palate between bites. The contrasting flavors enhance each other beautifully.
For an adults only celebration, pair with a gin and tonic garnished with cucumber, which complements the pickle notes perfectly. A crisp sparkling wine also makes an excellent accompaniment, as the effervescence cuts through the richness of the buttercream.
Consider serving this cake as part of a larger dessert table that includes other unexpected flavor combinations to create a tasting adventure for your guests. Small slices allow everyone to sample without committing to a full piece if they're hesitant about the concept.
