If you are a regular to my blog, it's no secret that I love citrus bakes. This blueberry lemon thyme loaf cake is one of my favorites and is MUST bake. This lemon cake is tender, fluffy and velvety, packed with lemon flavor with hints of herby fresh thyme, filled with juicy, fresh blueberries and drizzled with a sweet and tangy lemon glaze. It's so delicious, and so addictive - it's hard to eat just one slice.
How to make blueberry lemon thyme loaf cake
It's important to toss and coat the blueberries with a small amount of flour. This keeps them suspended in the cake so that they don't sink to the bottom of the cake during baking.
Butter is beaten with sugar, lemon zest and thyme to get maximum flavor from the aromatics until light and fluffy. Beat for the full 5 minutes so that the texture has lightened color and appears lighter and fluffier in texture. Vanilla and eggs are beaten in, followed by adding in and alternating dry ingredients and milk.
The blueberry/flour mixture is folded into the better to keep them the berries intact and also to not deflate the batter. I baked this cake in an 8 ½" by 4 ½" loaf pan but you can use a 9 x 5 loaf pan if you have that on hand. Bake until the loaf comes out clean or with a few remaining dry crumbs and the top is golden brown.
While the cake is cooling, prepare the glaze. Simply whisk together the confectioner's sugar, fresh lemon juice, and heavy cream until thickened and thoroughly mixed. The heavy cream helps to thickened the glaze and give it more of a creamy texture. This glaze is creamy and tangy, packing in even more lemon flavor. Pour or drizzle the glaze over the cake while it is still warm.
