I seem to have mostly Japanese sweets in my house these days.
It looks like I have more Japanese sweets at my house these days.
日本語の「〜めいてくる」というぴったりの言い方が英語にはないように思えますが、have mostly ... these day や have more ... these days を使って「最近〜めいてきている」のニュアンスが出せるかなと思います。
1) I seem to have mostly Japanese sweets in my house these days.
2) It looks like I have more Japanese sweets at my house these days.
参考になれば幸いです！
