Everyone knows that peanut butter and carrots are always a great pairing… so why not update the classic carrot layer cake by adding sweet Mighty Maple peanut butter to the traditional cream cheese frosting?

The end result is both delicious and impressive – three towering layers of moist, spicy carrot cake with plump golden raisins, all enclosed in swirls of tangy, maply frosting. The only downside is that you’ll be tempted to eat it all on your own, which is probably not a very good idea!

While layer cakes might seem a little intimidating, they’re actually much easier than you’d think. This one in particular is a great one for beginners – the sturdy layers of cake stack beautifully, and I’ve added a decorative garnish of chopped honey roasted peanuts that do wonders for disguising even the most imperfect of frosting jobs.

Make the Cake

4. Divide the batter between the prepared pans, smoothing out the top into an even layer. Bake in preheated oven for 30 minutes, or until cakes are golden brown and a toothpick inserted into the centers comes out clean. Set the pans on a wire rack to cool for 15 minutes, then remove from the pan and peel away the parchment. Let cool completely on the wire rack.

Prepare the Frosting

1. In the bowl of a stand mixer, whip together cream cheese and peanut butter until smooth.

2. Add vanilla and powdered sugar, 1 cup at a time, and continue beating until smooth. Add cream, 1 tablespoon at a time, until the icing reaches a spreadable consistency.

Frost and Decorate

1. Using a serrated knife, trim away any roundness from the top of two of the cakes to create perfectly flat discs. (The third can be left as is.)

2. Place the first trimmed cake layer cut-side up on a serving platter, and spread with 3/4 cup frosting. Top with the second trimmed cake layer, and spread with another 3/4 cup frosting. Gently place the final cake layer on top. Spread the remaining frosting over sides and top of cake in decorative swirls, and finish with a garnish of chopped peanuts.

    For example, the charging stand also works
    as a cleaner with several automatic programs based on the length
    of time. Other impressive product highlights include smart foil design (smart hair trimming), self-cleansing ability (clean and renew
    system), rechargeable battery (one hour fast charge and five-minute
    quick charge), and water-resistant shaving head (washable razor).
    Here are the main things anyone who wants to get a good
    electric shaver should look for.

    They cannot be large or they would bind and stall from contact with
    the wood. Chainsaws are a powerful and potentially dangerous
    piece of gardening equipment, and if you do not spend a little time choosing the appropriate machine for your needs they
    could also turn out pretty costly. So when those branches are on the verge of being intrusive the electric
    chainsaw provide the solution many gardeners are looking for to keep their
    gardens in tip top condition.
