How to Make This Recipe?

Step 1: Preheat the Oven

First things first, preheat that oven to 350°F (177°C). We want it nice and warm for our cake.

Step 2: Get the Pans Ready

Grease and line two 8-inch round cake pans with parchment paper. This will help that cake slide out like a charm later on.

Step 3: Whisk the Dry Ingredients

In a medium bowl, whisk together 3 cups of flour, 4 tsp of baking powder, 1 Tbsp of crushed lavender, and ¾ tsp of salt. You want that lavender smell to hit you—it’s gonna be SO GOOD.

Step 4: Cream Butter and Sugar

In a large bowl, use an electric mixer to cream together 1½ sticks of softened butter and 1½ cups of sugar until it’s light and fluffy. Seriously, keep mixing until it’s dreamy! Then, beat in the eggs, one at a time, along with 4 egg yolks and 2 tsp of vanilla extract.

Step 5: Mix it Up

Now, here comes the fun part. Alternate adding the dry ingredients and 1¼ cups of buttermilk into that buttery goodness. Start and end with the dry ingredients. Mix just until combined—we ain’t looking to overmix!

Step 6: Bake the Cakes

Divide the batter evenly between those pans and toss them in the oven. Bake for 25-30 minutes, or until a toothpick comes out clean. Let ‘em cool in the pans for 10 minutes, then invert onto a wire rack and let ‘em cool completely.

Step 7: Make Your Lavender Simple Syrup

While those cakes are baking, let’s whip up the syrup! Combine ⅓ cup of sugar, ⅓ cup of water, and 2 Tbsp of dried lavender in a small saucepan. Simmer over medium heat, stirring until the sugar dissolves. Once it’s done, let it steep for about 15-20 minutes before straining out the buds. Cool completely.

Step 8: Prepare the Buttercream

Beat ½ cup of softened butter until it’s creamy. Gradually add in 2⅓ cups of sifted powdered sugar until smooth. Mix in 2 Tbsp of cooled lavender simple syrup and 1 tsp of vanilla extract, beating it until light and fluffy. This frosting is going to take your breath away!

Step 9: Assemble

Now for the grand finale! Layer the cakes with that dreamy lavender frosting in between, then frost the top and sides. Go wild with it—make it as fancy or as homely as your heart desires!

How to Store It & Expert Tips

How to Store It

Keep your lavender cake in the fridge where it’ll last for about a week. You can also freeze slices for a rainy day—just wrap them in some plastic wrap and toss them in a freezer bag. They’ll be good for up to three months! When you’re ready to enjoy, just thaw overnight in the fridge.

Expert Tips

  • If you want to kick up the lavender flavor, add a tiny pinch more into your cake batter or frosting.
  • Don’t skip the resting time for your butter before beating it; a soft butter gives the best cream.
  • If you don’t have buttermilk, no sweat! Just add a tablespoon of vinegar or lemon juice into a cup of milk and let it sit for a few minutes.

FAQ Section

Can I use fresh lavender instead of dried?

Here’s the deal: Fresh lavender can work, but you gotta make sure it’s culinary-grade. Just remember to use less since it’s more potent!

What if I can’t find lavender?

Real talk, you can substitute with a bit of almond extract or even lemon zest for a fragrant twist!

Can I make this cake ahead of time?

Sure thing! You can bake the cakes and freeze them. Just frost it the day you plan to serve, and it’ll taste fresh!
