Lucky Charms Loaf Cake

This is the cutest, most colorful little loaf cake! It is made with limes, Lucky Charms cereal, and a little bit of Irish whisky (which you can totally leave out if you’re making this for kiddos). The cake is fluffy, and super yummy to have with tea, milk, or a cup of coffee. The glaze has a refreshing lime flavor that just adds some awesome tanginess to every bite! 

When I set out to make this cake, I realized I don’t bake many green desserts! At first I thought I would make the whole cake green, but something about that just didn’t feel like it would be right unless I was going to use matcha, which I wasn’t for this cake. So instead, I decided to keep the cake naturally colored – there are bursts of different colors within the cake due to the Lucky Charms marshmallows swirled in though! I decided to go with just a drop of green food coloring for the glaze, to make this a festive St. Patrick’s Day dessert. If you prefer to leave out the food coloring, that’s fine too! 

What you’ll need. . . 

• unsalted butter
• eggs
• granulated sugar
• brown sugar
• sour cream
• lime juice
• lime zest
• vanilla extract
• Irish Whiskey
• flour
• cinnamon
• baking powder
• baking soda
• salt
• Lucky Charms cereal
• powdered sugar
• green gel food coloring

Making the batter

1. Lately I’ve been into minimizing whenever I can, just to save time on clean up! So everything is pretty much made in one large mixing bowl, except for the glaze, which I’ll explain next. For the batter, melt 1/2 cup butter in a microwave safe glass. Add that to your large mixing bowl. Let cool about five minutes. Add in the eggs and whisk together. Next whisk in both sugars. Now add in the rest of the wet ingredients and whisk until combined. 
2. Switch to your silicone spatula. Add in the dry ingredients ( not the cereal) and fold in until combined. Preheat your oven to 350F. 

How to Assemble the Loaf Cake

1. Butter a 9 inch loaf pan. Next use a rectangular parchment sheet to line the pan. I like to cut the corners with scissors to help it fold into place. Then add a little extra butter behind the parchment to make sure it sticks to the pan and doesn’t lean too much into the batter. 
2. Spread 1/3 of the batter in the bottom of the pan. Next add a layer of Lucky Charms cereal, making sure to get a nice mix of marshmallows and some of the regular pieces. Add another 1/3 layer of batter. Add another cereal layer. Add your last layer of the batter and use a knife to swirl the cereal around a bit. 
3. Bake for 40-45 minutes, or until a toothpick comes out clean. Remove and let cool completely while you make your glaze. 

Making the Green Glaze

1. Mix melted butter, fresh squeezed lime juice, powdered sugar, and vanilla together until smooth. I use a fork to mix them in a small bowl. Next add in a small drop of the green food color and mix until uniform.
2. Push the glaze through a strainer to get any lumpy sugar out. Now add some lime zest. Pour glaze over cake and arrange cereal on top. 

Some Notes. . .

1. Whiskey can be left out if you choose!
2. Green gel color can be left out as well!
3. Loaf can be stored in an airtight container for 1-2 days.
